In the early days of People’s Republic of China, Mao Zedong attached great importance to dealing with the relationship with the masses. He put forward numerous new viewpoints: Addressing the relationship between the Party and the masses is of great significance to the Party and the country; the focus is to emphasize and rely on the masses; the key point is to contact the masses; the fundamental point is to benefit the masses; In dealing with the relationship between the Party and the masses, we should do a good job in publicity and education to the masses, make good use of the methods of criticism and self-criticism, and build a good team of Party members and cadres. The study of these thoughts can provide enlightenment and reference for the Party’s work with the masses under the new situation and building a harmonious relationship between the Party and the masses in the new period.

Through combing the quotation and evaluation of Mao Shi Chuan Jian Tong Shi by the academic works in late Qing Dynasty, it is found that Ma Ruichen’s interpretation of characters by borrowing method not only was the inheritance of Qianlong and Jiaqing academic heritage, but also left scholars in late Qing dynasty with sufficient academic references. He proved Maoshi with three versions of Book of Songs, which laid a solid foundation for the scholars’ research on three versions of Book of Songs in the late Qing Dynasty. However, scholars in late Qing Dynasty did not pay enough attention to Ma Ruichen in their studies of Book of Songs. This paper analyzes the quotation and evaluation of Mao Shi Chuan Jian Tong Shi in the academic works of late Qing Dynasty, and discusses Ma Ruichen’s influence on the study of Book of Songs in late Qing Dynasty, so as to present a comprehensive understanding of the academic value of Ma’s Tong Shi in the history of studies on Book of Songs in Qing Dynasty, and supplement the academic research in this aspect.

Rapid detection of sulphonamide antibiotic contamination in the environment is important for water environment monitoring and management. To fabricate carbon quantum dots based fluorescent molecularly imprinted sensor（CQDs-MIP） with specific recognition ability for sulfamethazine, nitrogen-doped carbon quantum dots, 3-aminopropyltriethoxysilane, ethylene glycol dimethacrylate and sulfamethazine were used as the fluorescence source, functional monomer, cross-linker and template molecule respectively. The effects of functional monomer addition, solvent type and cross-linker type on the performance of CQDs-MIP were investigated by adsorption experiments. The experimental results showed that the adsorption process of CQDs-MIP on sulfamethazine was in accordance with the Langmuir adsorption isotherm model and the second-order kinetic equation, and showed high selectivity for sulfamethazine with the selectivity coefficients of 2.28 and 3.02 with respect to sulfadiazine and sulfadimethazine, respectively. The linear range of CQDs-MIP for sulfamethazine was 2~100 mg·L^-1 with a linear correlation coefficient of R² = 0.9972; CQDs-MIP has the ability to detect sulfamethazine rapidly and sensitively.

This paper analyzes the impact of digital economy on the integration of traditional cultural industry and tourism in Chaohu Lake area from 2012 to 2019 based on coupling coordination degree model, and introduces social network analysis method to explore the moderating effect of economic network centrality. The results show that the integration degree of traditional cultural industry and tourism is increasing in recent years; Hefei enjoys the best performance, followed by Chaohu city, Feidong county, Changfeng county, Feixi county and Lujiang county. The development of digital economy significantly promotes the integration of traditional cultural industries and tourism; the digital economy network, tourism economy network and traditional culture economy network all present "core-edge" structure, but the density is low. The Hefei municipal district is in the core position in the three networks. The centrality of the three networks positively regulates the impact of digital economy on the integration of traditional cultural industry and tourism. Finally, policy suggestions are put forward on promoting the development of digital economy, strengthening the penetration of digital technology in traditional cultural industry and tourism, and strengthening the economic ties between regions.

A lot of meticulous clothing-writing is used in Madame Bovary, which embodies Flaubert's cognition and reflection on the fashion of French society in the early 19th century, and it is also a new perspective to analyze the fate of Emma. As a literary representation of fashion, clothing-writing is the key to interpreting the modernity connotation of the novel. The transformation of French society in the period of modernization is manifested in the change of people's aesthetic concepts and consumption behavior. Emma is in the process of modernization that has never happened before, so her tragic fate has the special reason of the times. Flaubert, in Madame Bovary, vividly shows the modernity connotation driven by material fashion behind the character's fate, and presents the dimension of fashion showing people's internal desire of "unification" and "differentiation".

The Young Companion was engaged in the mental construction of the provisional capital and envisioned the urban Chongqing from the perspective of a third party. The Chongqing bombing was not the focus of the report, or rather the report was a strategic narrative based on the setting of the agenda. Due to the coexistence of the big bombing and the Chongqing landscape, "two Chongqings" appeared to be separated from each other. However, to the readers of Shanghai as an "Isolated Islet", the two were not contradictory. The scenic Chongqing and the bombed Chongqing were behind the "visor effect" mentioned by Jacques Derrida, and they both conveyed similar implications, i.e., the big bombing would not affect Chongqing's status as the provisional capital nor could it have any impact on the overall situation of the Chinese People's War of Resistance against Japanese Aggression. What the readers, represented by the "Isolated Islet" people, had to do was to follow the values conveyed behind the "visor effect", i.e., absolute confidence in the victory of the war of resistance, and more importantly, they must approve of the deployment of the Chongqing National Government for material and spiritual resources to ensure winning the war of resistance. This orientation was not only the commonality of some anti-Japanese newspapers and periodicals, but also the result of the special perspective of The Young Companion as one of the "Isolated Islet" anti-Japanese newspapers and periodicals.

The Zhongzong Dynasty first began to regard Wang Bo, Yang Jiong, Lu Zhaolin and Luo Binwang as a literary group, and called them "four outstanding men" or "four talented men". Although people including the four outstanding men discussed the issue of ranking, those discussions were scattered and inconclusive. Since the Song Dynasty, "Wang Yang" and "Lu Luo" frequently appeared as pairs. Later, maybe because of the pronunciation habit of "flat front and narrow back", they were identified as "Wang Yang Lu Luo". Influenced by Zhang Shuo and Liu Su's "Pei Xingjian's comments on the four outstanding men", there were many cases in Tang and Song Dynasties where the official selection criteria of "valuing morality but belittling literature and art" was used to belittle the "four outstanding men". Du Fu was the first to rectify the fame of the "four outstanding men" from the standpoint of poetry criticism, and regarded them as a key link in the development of literature in the Tang Dynasty. With the deepening of the people's understanding of the development stage of poetry and prose, Wang, Yang, Lu and Luo's literary ideas and writing practice of inheriting Qi and Liang traditions and ushering in Tang literature got recognition. Finally, the four talents became the representatives, side by side with Shen, Song and Chen Zi'ang, of the literary circle of the early Tang Dynasty.

It is of necessity to explore the four notions of Ji (寄), Xiang (象), Didi (狄鞮) and Yi (译) in Book of Rites. No systematic and profound research has been conducted on the four notions. The present research on the four notions can help shed light on the connotation of "language of Yidi (夷狄)" used by Kong Yingda, the respective origins of Ji (寄) and Yi (译), the correspondence among Di (狄), Di (的) and Di (敌), and the far-fetchedness of "the popularity of Yi (译) on account of Han (汉)". All these serve to deepen the understanding of the four notions and offer a new approach to some related notions of modern translation studies.

In Dai Zhen's ethics study, Fen Li means the distinction and integration among human beings, the core of which is the general "desires". In order to clarify the Fen Li, he adopted the way of Yi Qing Xie Qing. However, there is a possibility that this method may ignore others' "desire" claims in practice, so we still need to optimize it. Later scholars added Xin Zhi, an intellectual concept, to Xie Qing and this paper introduces the concepts of "don't do to others what they don't want" and dialogue. On the one hand, it elevates the other to the level of non-assimilation; on the other hand, it presents others' "desires" through dialogue, which can further advance the Xie Qing on the path of clarifying Fen Li.

This article draws on Bourdieu's theory of field of literary production and discusses the concept and practice of drama during the New Culture Movement, so as to read the historical scene comprehensively and avoid the ignorance of facts due to limited vision. By combing through the interaction between drama debates and reality before and after the New Culture Movement, this article can help understand the interpretation logic of the secondary field of drama production during the period: struggling and occupying positions in the field based on political ideals, which involves resistance against economic capital. The surrender of the old drama and the civilized new drama to economic capital is no longer suitable for the social responsibility that the secondary field of drama production is required to shoulder. Therefore, the drama dispute and the generation of modern drama show a different feature, which stems from the tense relationship in the social field and the consensus on the social function of drama.

In ancient Chinese art criticism, there were such artistic creation methods as Shi Xin (follow heart), Shi Gu (follow the ancient) and Shi Zaohua(follow creation), which provide reference for artistic creation in the process of art evaluation in past dynasties. In different times and schools, the objects of Shi Fa(follow the law) in artistic creation were different, which reflected the value and aesthetic orientation of art and artists at that time and became the benchmark and reference for artistic creation in the same period. By combing the art criticism literature on Shi Fa through ancient dynasties, this paper analyzes the changes of the object of Shi Fa with the background of specific historical periods, analyzes the artistic category of Yi(freedom) produced in the deviation from and return to Fa(law), studies the "two-way" interaction between the subject and object in the aesthetic connotation of Shi Fa, and summarizes the evolution of Shi Fa in the art criticism thought in ancient dynasties in China and the deviation from and return to Fa.

[Objective] Succinic acid and lactic acid are the main products when Corynebacterium crenatum were cultured under anaerobic conditions. The knockout of lactate dehydrogenase gene(LdhA), a key enzyme for lactic acid production, can decrease the production of lactic acid and increase the flux of the metabolic pathway for succinic acid production. [Methods] In order to obtain the C. crenatum ?LdhA mutant strain, the upstream and downstream homologous recombination genes of LdhA and kanamycin resistance gene (Kn) were obtained by PCR. Afterwards, the targeting homologue recombination DNA and plasmid were constructed by fusion PCR. [Results] The targeting homologue recombination DNA of ?LdhA::Kn, targeting plasmid of pCVD442-?LdhA::Kn and donor bacteria of E.coli β2155/pCVD442-?LdhA::Kn were constructed, and the mutant strain of C. crenatum which had resistance to kanamycin was screened. [Conclusion] The results of PCR and lactate dehydrogenase activity analysis indicated that the LdhA in genome of C. crenatum was knockout and replaced by Kn. This study provides a foundation for producing succinic acid efficiently using C. crenatum.

During the Ming and Qing Dynasties, epidemic diseases in Chaohu Lake basin lasted for 36 years. The formation of epidemic diseases was the result of the comprehensive effects of natural environment and climate characteristics, natural disasters, and social changes. In terms of natural environment, the general climate during the Ming and Qing Dynasties and the unique environmental characteristics in Chaohu Lake basin contributed to the epidemic diseases. In terms of natural disasters, the disaster system formed by the association of disaster elements formed the environment of epidemic diseases. Among them, the disaster elements of water, drought and locust were related to the formation of epidemic diseases most directly. In terms of social factors, epidemic diseases reflected the comprehensive effects of national epidemic prevention efforts, population changes, economic development, wars, and famines. The combination of multiple factors constituted the ecological field of epidemic diseases.

The revolutionary base areas of Western Hunan and Hubei is one of the three Soviet areas led by the Communist Party of China in the period of the New Democratic Revolution. In the harsh revolutionary struggle environment, there were problems in the number, quality and production of cadres in the base areas, such as shortage of numbers, prominent ideological and political problems and dependence on the appointment system. It was urgent to carry out cadre education. Under the leadership of the Party, the revolutionary base actively carried out cadre education practice, such as improving the comprehensive quality of cadres with military academies, Party schools and training classes; innovating cadre inspection methods, promoting outstanding cadres from practical work; carrying out ideological and political education for the whole party. Through the above practice, the Party's cadre education in the revolutionary base areas of Western Hunan and Hubei achieved remarkable results: it enhanced the military skills and combat ability of cadres, forged a large number of local revolutionary talents, improved the ideological and political theory level of cadres, optimized the class status of the cadre team, and strengthened the discipline of cadres within the party.

The belief in Jiao Mu has a history of eighteen hundred years, and it has become an important local belief in Chaohu region. The text of Jiao Mu legend has dozens of versions from the "Annals of Three Kingdoms" to its interpretation in modern times. Behind the accumulation of texts is the tension between foreign beliefs and Jiao Mu belief, which constantly adapts to the change of times. And the constant of Jiao Mu belief is reflected in its characteristic of being limited to the local region. After thousands of years of spreading, the Jiao Mu belief has stayed in Chaohu region. This characteristic of being local is closely related to the Jiao Mu belief itself, the degree of official acknowledgement and the folk customs of Chaohu region. The locality of Jiao Mu belief dissemination is not in contradiction with the universal value of Jiao Mu. Making full use of Jiao Mu belief and its cultural connotation will be beneficial to the discourse power of Chaohu regional culture.

The "literati in the Tingzijian" (which means literati in the pavilion) was originally proposed by Mao Zedong, but the definition of its concept wandered between generalization and unidirectionalization. The space oppression of the "Tingzijian" mirrors the literati's perception of the "proximal order" and the "remote order". The former makes the literati appear heterogeneous in getting along with the bottom workers in shanty towns and the ordinary citizens of Shanghai, so it is also far from the "popular literature and art", while the latter reflects the marginal dilemma of the "literati in the Tingzijian" in the vertical form through the comparison of cultural capital, social capital and the center of the literary field. At the same time, the enclave characteristics of the "Tingzijian" have further shaped the habitation ecology of young literati, and strengthened the power of the Left League. The two generations of "literati in the Tingzijian" moved from the margin to the center along the ascending path of the literary production mechanism, but the differentiation among the "literati in the Tingzijian" also has more room for interpretation.

In April 1912, a criminal case of a Japanese murdering a Chinese occurred in Shanghai concession, which aroused heated public discussion and concern. At that time, the Republic of China was in its infancy. With the regime change, the internal and external situations were complicated. After China's efforts, the case was finally won by China, and the Japanese were sentenced to life imprisonment and compensation. To a certain extent, the result safeguarded national and civil rights, and provided a reference for the future handling of similar cases. Through this case, we can see the efforts of modern Chinese people to maximize their rights and interests under the restriction of consular jurisdiction. It provides a new perspective for the study of consular jurisdiction.

As a type of unearthed documents, inscriptions are important materials for the study of ancient languages, history, and culture. Characters of popular forms are the supplement and reserve force of the orthographic system. Following the trend of the Han, Wei and Six Dynasties, the characters of popular forms in the Northern Zhou and Sui dynasties are still complex, which is a valuable material for the study of Chinese character history. It is the variety of styles and strange shapes that make it difficult to interpret the stele inscriptions during this period, and the collections of the inscriptions often misinterpret the characters of popular forms. This paper selects twelve characters of popular forms among them and corrects with evidence their faulty interpretation, providing reference for the study of modern Chinese characters and the history of Chinese characters.

Since the founding of the Communist Party of China (CPC) one hundred years ago, it has always attached great importance to the issue of inner-party supervision. The party constitution is not only the fundamental law of the party, but also the fundamental principle to adhere to in strengthening the supervision within the party.An important aspect of the party's attention to inner-party supervision is reflected in the provisions and amendments of the party constitution to inner-party supervision. From the first CPC National Congress program to the 19th National Congress constitution, the provisions on party supervision, has experienced four stages: initial formation,promotion and retrogression, development and perfection, and the latest deployment. Through the historical investigation of the relevant contents of the party constitution on the supervision within the party, this paper summarizes and studies its experience and enlightenment, which is of great significance to further strengthening the supervision within the party and promoting the comprehensive and strict governance of the party under the new situation.

The ecological status of Chaohu Lake Basin is particularly important in Anhui province and even in the whole country. In recent years, the environment of Chaohu Lake Basin has been significantly improved by the government, but there are still some environmental problems. Combing the current relevant laws and regulations for Chaohu Lake Basin, summarizing the current legislative situation, we find that there are problems such as unbalanced legislative structure and scattered system, insufficient ecological legislation, imperfect legislative content and so on. According to our country' s ecological civilization concept and practical experience of comprehensive legislation in the basin, we should make comprehensive legislation in Chaohu Lake Basin, formulate the Regulations on Protection of Chaohu Lake Basin, improve the ecological concept of legislation, and construct and improve the legal system from the aspects of improving the overall environmental protection planning system, environmental impact assessment system, ecological protection compensation system and government environmental responsibility investigation mechanism, so as to provide institution guarantee for ecological protection in Chaohu Lake Basin.

Following the educational philosophy of outcome -oriented approach and sustainable development, this paper puts forward and practices an applied course group teaching system to cultivate students' professional behavior and ability, which integrates teaching, learning and practicing. For the teaching, the coverage or close connection of knowledge points among different professional courses in software development direction result in repeated teaching and isolation of course content in the course teaching process. To deal with this problem, this paper proposes project-oriented applied course group collaborative teaching mode. The framework of software development course group is first introduced; then this paper expounds this cooperative teaching mode in three aspects: designing comprehensive teaching cases, collaborative teaching method for the same ability stage and smooth course transfer among different ability stages. For the learning and practicing, this paper proposes taking curriculum design as the starting point to form cooperative practice platform for solving the problems of limited class hours, outdated teaching content and simplistic teaching mode and gives detailed explanations from content design in curriculum design, implementation route, multi-level and multi-dimensional assessment mechanism. For the comprehensive ability training, considering that it is difficult to improve students' ability of "solving complex engineering problems" resulting from the discontinuity of ability cultivation caused by isolated teaching, this paper discusses how to construct a comprehensive training system oriented around professional behavior and ability in line with the software development cycle.

According to the national standards of tourism classification, the Analytic Hierarchy Process （AHP）is used to establish the evaluation index system to determine the weight value of each indicator and comprehensively evaluate the rural tourism resources around Chaohu Lake. The nearest neighbor index, standard deviation ellipse and buffer analysis are used to carry out spatial distribution characteristics research from the aspects of distribution type, direction, and distance. The results show that the diversified types of rural tourism resources around Chaohu Lake have obvious effects, and the combination is in good condition, but most of the resources are of low grade,with average appearance, low visibility and influence, and lacking market attractiveness; rural tourism resources are unevenly agglomerated. The spatial distribution of rural tourism resources is unbalanced and concentrated along the northeast-southwest direction, and clusters along the main roads, with significant traffic dependence. At present, the development of rural tourism around Chaohu Lake is in its infancy, lacking a "connotative" development plan, and no tourism synergy has been formed. From the perspective of global tourism, combined with the current development of rural tourism around Chaohu Lake, we propose a new rural tourism space pattern of "one lake, one corridor, three cities and four districts", and strive to create a rural tourism circle around Chaohu Lake. The purpose is to promote the establishment of the tourism destination and realize the strategic goal of Rural Revitalization.

Mobile short video has become an important way for users to obtain information and relax. The presentation of mobile short video cover is the direct entrance for users. High quality of short video cover's presentation can help attract more attention. Based on the information adoption model, combined with situational learning theory and schema learning theory, this paper studies the effect and mechanism of mobile short video cover presentation on users' intention. It is found that perceived usefulness plays a mediating role between the presentation of short video and users' intention. The type of short video plays a moderating role in the influence of its presentation mode on users' perceived usefulness.

During the reign of Qianlong and Jiaqing, calligraphy was faced with the increasing popularity of the new aesthetic trend of Stele Study, coupled with the wide use of new tools and materials such as raw paper and wool brush. A new technique system, especially the ink method, had yet to be established. Deng Shiru, who has gained the momentum of this era, diligently made full use of the characteristics of raw paper and wool brush, and formed a distinctive style of ink painting, which is elegant, ancient and thick, and has the spirit of epigraphy. By analyzing the internal aesthetic mechanism of the formation of Deng Shiru's ink style, starting from the theoretical analysis of the relationship between his ink style and spirit of epigraphy, brushwork and space, and combining with the image analysis examples of his works, this paper makes an in-depth interpretation of the performance skills and aesthetic connotation of his ink style, in order to help readers understand Deng Shiru's influence in the history of calligraphy and gain some insights.

The version origin and compilation process of Annotations to the Plants and Animals in Mao Poetry written by Jiao Xun can be clarified by comparing the 20-volume manuscript collected in Fu Si-nian Library of Taipei Academia Sinica, the one volume manuscript, the 30-volume manuscript and the 11-volume manuscript kept in Shanghai Library. The 11-volume manuscript was revised mainly based on the 30-volume manuscript, referring to the 20-volume and the one volume and other early manuscripts at the same time. The 30-volume manuscript laid the foundation for the compilation of the 11-volume manuscript in terms of content and style. After that, Jiao Xun took the 30-volume manuscript as the base and made a series of adjustments, including adjusting the compilation style, correcting errors, changing the arguments and so on. He finished the definitive edition in 1799. Investigating the compilation process and edition source of this book is conducive to the study of Jiao Xun's academic achievements.

Children's cartoons imported from the Western countries are often dubbed into Chinese. The Chinese version of Peppa Pig is a successful example, but its Chinese language is over-Europeanized in the English to Chinese translation. The study, based on the comments on over-Europeanization by Yu Kwang-chung and Xie Yaoji, analyzes and classifies the over-Europeanization in the Chinese version of Peppa Pig. It is found that there are unnecessary structural words and personal pronouns at the lexical level; long subjects, long pre-modifiers and over-used passive voice marker bei at the syntactic level; and improper diction in the context of children's cartoon. Such over-Europeanized language lost the authentic Chinese language's advantages of flexibility and concision and is not good for children's Chinese learning. Suggestions for language improvement are put forward from the four aspects of government, producer, translator and proofreader.

Public security admonition is an admonition measure similar to criticism and education, which is carried out for minor offences that are not serious enough to be punished according to the Public Security Administration Punishment Law. Its function and purpose are similar to the "warning" in administrative punishment, but there is no relief channel. These realistic contradictions provide space for abusing public security admonition. Whether the admonition is an administrative punishment depends not only on its external manifestation, but also on its content, legal basis and purpose. In addition, whether the public security admonition is an administrative punishment measure and whether it belongs to the scope of administrative cases should be analyzed through case study. One important factor is whether the contents in the admonition have actual influence on the rights and obligations of the administrative counterpart.

Objective: To clarify the relations among the English words semantically associated with moon, including their etymologies, cultural implications and usages. Method: Adopting Indo -European philological study to investigate the related etymological issues, especially in sound change. Conclusion: Some related words are of IndoEuropean origin while others are otherwise derived; some related words function in word-formation while others do not. Significance: A systematic study of semantically related words concerning moon within the framework of IndoEuropean philology is new research, beneficial for both theoretical study and English lexical teaching practice.

Since modern times, the Chinese view of Japan is evolving with the increasing frequency of exchanges and confrontations, especially the reversal of the comparison of national strength. Xu Zhaowei, a gentleman frombsouth of the Yangtze River, lived in a period of great changes in modern Sino-Japanese relations. Xu Zhaowei wroteba diary for nearly half a century. The diary contained many contents related to Japan, which provide important historical data for scholars to study Xu's view of Japan. The failure of the Sino-Japanese War of 1894-1895 had a great impact on Xu Zhaowei. Consequently, he analyzed Japan's successful experience in order to seek a strategy to save China. More and more people demanded to learn from Japan with the victory of Japan in the Russo-Japanese War and the promotion of the New Deal in the late Qing Dynasty. Therefore, Xu Zhaowei went to Japan to study the advanced civilization. Since then, Japan's ambition to invade China has been continuously highlighted, especially after the outbreak of the overall anti-Japanese war. Xu Zhaowei recorded the Japanese atrocities in south of the Yangtze River. The evolution of Xu Zhaowei's view of Japan in his personal life history is also the epitome of SinoJapanese relations during this period.

As an independent relief measure, the establishment of personal safety protection order system enriches the legal connotation of anti-domestic violence work and makes up for the lack of legal regulation of domestic violence in China's judicial practice for a long time. After four years of exploration and practice in the implementation of China's Anti-Domestic Violence Law, the basic application process has been formed and the basic quality effect has shown. However, due to the late start of the system in China, there are still some problems in the process from the written law to the specific implementation, such as low application rate, difficulty in proof, difficulty in identification, and difficulty in implementation. This paper mainly uses the methods of comparative research, literature research and empirical analysis, starts from the case study of Anhui Province personal safety protection order issued by China judicial document network, deeply analyzes the implementation difficulties of personal safety protection order in practice, and puts forward suggestions on how to stimulate the vitality of the system from the aspects of top-level design, evidence rules, working mechanism and disciplinary measures.

Novecento is one of the masterpieces of the Italian writer Alexandro Barrico. The protagonist Novecento's rejection of disembarkation has aroused wide discussion. Many researchers have paid attention to the passive side of Novecento's behavior, which led the researches to slide into childhood determinism. This paper intends to explore the relationship between heterotopia and authoritative space in this play, and attempts to explain that Novecento's rejection of disembarkation is motivated by the power of heterotopia. When authoritative space attempts to invade and control the Other in heterotopia, the Other also endeavored to resist it.

Firstly, a 3-DoF hybrid vibration screening mechanism is designed, and the degree of freedom of the mechanism and the motion characteristics of the screening surface are analyzed. Through the analysis, the motion of the screening surface can be obtained. Secondly, the vector closed form method is used to analyze the positive and negative solutions of the mechanism, and the corresponding position equations are obtained, and the mathematical expressions of the positive and negative solutions of the velocity and acceleration of the mechanism are obtained by derivation. Finally, ADAMS is used to simulate and prove that the 3-DoF hybrid vibration screening mechanism can realize two translations and one rotation, which provides a theoretical basis for the dynamic modeling and practical application of the 3-DoF hybrid vibration screening mechanism.

Large-scale public buildings are dense with crowds, and building noise is easily affected by crowds and other dynamic and complex factors. As the numerical simulation of building noise pollution is time-varying, complex, and nonlinear, a numerical simulation method of assessing building noise pollution based on adaptive transfer function is proposed. A building noise pollution monitoring system based on the Internet of Things is built to monitor the environmental elements of building noise in real time, analyze the frequency spectrum of building noise pollution sources by adaptive functions, and use the effective value of acceleration, vibration acceleration level and vibration level to measure building noise pollution according to urban environmental noise standards. Noise pollution intensity and level are determined to complete the building noise pollution numerical simulation calculation. The effectiveness of the proposed method is verified by experiments. The results show that the simulation calculation method designed this time is more accurate than the traditional method and is closer to the actual measured value. It has higher applicability and provides reference for numerical simulation of building noise pollution.

In the Qing Dynasty, Hanshan Qingshi, a typical family of imperial examination officials, rose in the local area. In the family, Zhang huanxin, Qing fengting, Qing fenghui and Qing peiyun were all well-known for composing poems, which made Qingshi family more famous. Along with the influence of geography, times and family traditions, it was their good family tradition that made their culture of talented ladies rise through time. The two aspects influenced promoted each other, forming a benign interaction. A case analysis of the family's tradition and culture of talented women can help understand the internal mechanism and reasons for the prosperity of the culture of talented ladies in the traditional family, and further deepen our understanding of the culture of talented ladies in the region around Chaohu Lake.

COVID-19 epidemic has brought severe challenges to China's national governance system. As an important "epidemic" front in the fight against COVID-19 epidemic, online public opinion management aims at balancing the free expression of the public and risk control. In the new media era, COVID-19 epidemic has formed a complex public opinion field in cyberspace, which has increased the difficulty of government governance and exposed the governance defects of traditional social governance model. Comprehensive governance can effectively make up for the shortcomings of the traditional social governance model. Scientific prevention and accurate measures should be carried out from the three dimensions of governance concept, governance principles and methods and governance system. We will improve the governance efficiency of online public opinions on public health emergencies, form a new pattern of social governance on public health emergencies, and modernize the country's governance system and capacity.

The Italian Wars of 1494—1559 demonstrated the multi-layered interaction between military technology, war and society in the transformational period of Europe from the 15th to the 18th century. The military and social outlook of Europe took on a new look during the interaction between the Italian Wars, the Renaissance, and Religious Reform and so on, which became a powerful momentum to promote the transformation of Europe from the Middle Ages to modern times. At present, scholars at home and abroad tend to explore the overall process of the Italian Wars, the issues of technology and society in the Wars and the mercenary issues during the war, and have made some achievements in exploring the European history in the political, military, diplomatic and social aspects during the transformational period. However, there are still some deficiencies in the current Italian Wars research, such as the tendency of homogeneity, the lack of interdisciplinary integration results and the lack of "humanistic care" in the social field. If we can correctly understand the importance of Italian Wars and introduce new research methods and perspectives, the research on Italian Wars in the transformational period will gain more remarkable achievements.

For the new coronavirus epidemic situation, our government decisively exercised the administrative emergency power and initially restrained the development of the epidemic situation. In order to ensure the safety of people's lives, the strict control measures adopted in this epidemic reached an unprecedented level. Many scholars pay attention to the problems in the exercise of administrative emergency power, especially the restrictions on civil rights. Some scholars dispute the legitimacy and rationality of the control measures. Based on the analysis of the basic principles of administrative law, it is found that the crux of the dispute lies in the imperfection of the legal system of emergency state, the lack of supervision of the normative documents of administrative emergency and the judicial incoordination in the regulation of administrative emergency power. These disputes can be resolved by improving the legal system of emergency, giving full play to the supervision role of the constitutional review system and clarifying the standards of judicial review after the event.

In the special era of the late Ming and early Qing dynasties, Gu Yanwu made a deep reflection on historical traditions and realistic issues, and put forward the famous distinction between "the state" and "the world".Gu Yanwu's "state view" summarized the historical commonality of "state" and believed that "state" is a political entity that integrates the three elements of the ancestral temple, community and territory. Gu Yanwu's "view of the world" is based on the history culture and language traditions of "the world"; "benevolence and righteousness" are the core connotations of "the world"; the construction of "customs and morals" is the practical strategy of "protecting the world"; "protecting civilization from barbarism" is the highest principle with national interests and civilized life as the top priority. Gu Yanwu determined the prerequisite importance of "the world" to "the state", clarified the division of responsibility within civilization, and established everyone's "subjectivity of responsibility" for the development of civilization and nation.Gu Yanwu completed the reconstruction of the meaning of "the world" through reflection on "history" and "reality". It constitutes an important content in the historical semantic change of the concept of "the world", and has played a huge role in Chinese history. It has also become an important cultural resource for the social construction and ideological development of modern China.

Based on the SBM-DEA and Malmquist models, the tourism efficiency and Malmquist productivity index of International Cultural Tourism Demonstration Area in Southern Anhui Province in 2009—2018 were measured, and with the ArcGIS analysis platform, the temporal-spatial evolution characteristics of urban tourism development efficiency were studied. The study found that in the time dimension, the annual average of tourism efficiency fluctuated, and the gap between cities was small and shrinking; most cities had the problem of "high input and low output". From the perspective of Malmquist after decomposition, technological progress has a certain effect on the improvement of total factor productivity. In the spatial dimension, tourism efficiency presents the inner circle structure with "Chizhou-Huangshan" as the core, and the central city has a certain space "spill effect"; the tourism efficiency and the center of gravity of the Malmquist index are alternately "east-west" . Based on this, suggestions for optimizing the efficiency of tourism resource allocation are put forward, providing reference for the continuous and intensive development of International Cultural Tourism Demonstration Area in Southern Anhui Province.

"Wuchang Taiping Lantern" is one of the main types of the national intangible cultural heritage "Dongzhi Lantern". It has a long history and rich meanings. It integrates the original cultural symbols such as folk songs and dances, original crafts and religious beliefs. It embodies the collective memory of the local people and reflects the spiritual outlook of the working people. The research on "Taiping Lantern" takes into account both diachronic and synchronic perspectives. On the one hand, through the description of "space", the research explores its historical origin and reveals its spatial state and regional structure of occurrence and development in "change" and "invariance"; on the other hand, its deductive form is interpreted to decipher the multicultural connotations contained therein, and identify the "idol" and "reality" according to the universality of the ritual, which is beneficial to the exploration of inheritance and the protection of the regional and minority intangible cultural heritage represented by the "Wuchang Taiping Lantern".

By constructing the model of industrial upgrading, real exchange rate and exchange rate system reform,the relationship between exchange rate system reform, real exchange rate and industrial upgrading is deeply studied by using EG two-step, ARCH and GARCH methods. The rise of the RMB exchange rate will help China忆s industrial upgrading, but the upgrading of different industries affected by the RMB exchange rate is asymmetry. The RMB exchange rate has greater impact on light industry upgrading and smaller impact on heavy industry upgrading. Relatively loose, flexible RMB exchange rate system has a positive impact on industrial upgrading. Finally, according to the research results, the corresponding policy recommendations are put forward

In the report of the 19th National Congress of the Communist Party of China, Xi Jin-ping first put forward the new proposition of "political construction of the Party". The pioneers of proletarian revolution,represented by Karl Marx, Lenin and Mao Ze-dong, carried out a lot of practical explorations, which laid an important theoretical foundation for the Communist Party of China to carry out the Party's political construction after the founding of new China. During the past 70 years, the Party's political construction has undergone four stages of development: initial exploration during the period of socialist transition, tortuous progress during the period of socialist construction, the beginning of a new period of reform and opening up, and the comprehensive strengthening in a new era of socialism with Chinese characteristics. The article studies the historical experience of the Party's political  construction over the past 70 years, in particular the effective measures and typical practices in the fields of ideological and theoretical support, political line formulation, study and education, and system building. It has important value to promoting the political construction of the Party in the new era.

The supply of basic public services in rural sports plays an important role in promoting the development of rural economy, society and culture. In the past 70 years, great progress has been made in the basic public service of rural sports. By using the methods of documentation, questionnaire and interview, this paper combs the development, evolution, actual situation and characteristics of the basic public service supply mechanism of rural sports in China from the historical and realistic perspectives, analyses its performance, explores the existing practical difficulties, and explains the urgency and conditions for the innovation of the supply mechanism of the rural sports public service in the new era.

The implementation of the rural revitalization strategy was proposed on the 19th National Congress of the Communist Party of China. The issuing of the rural revitalization strategic plan (2018-2022)is conducive to solving the stage contradiction in the development of rural economy and society. The entrepreneurial practice of college-graduates village officials is restricted by external factors such as regional environment, policy guarantee and support system, as well as internal factors such as entrepreneurial motivation, entrepreneurial ability and social resources. By establishing the mechanisms of guidance, guarantee, support, service, adjustment and incentive, efforts can be made to promote the long-term development of entrepreneurship of college-graduates village officials, which will enhance the implementation of rural revitalization strategy

Abstract: The Doctrine of the Mean is an important component of Confucianism, a doctrine of thought founded by Confucius. On the one hand, this thought has been inherited and spread, profoundly affecting the Chinese people;on the other hand, it is often misunderstood and even criticized. A close reading of the Analects of Confucius reveals that the Doctrine of "the Mean" is actually the unity of three connotations: doctrine of harmony, doctrine of viability and doctrine of contingency.

Authorial voice construction is an important part of academic English writing. The study, based on the Voice interactive model, proposes that understanding the characteristics of the authorial voice in academic English writing, analyzing its textual function and mastering the language resources of the authorial voice construction are the prerequisites for its construction. It finds that authorial voice in academic English writing has personal, social and interactive characteristics, which are interdependent and inseparable. Furthermore, In academic English writing, the authorial voice has the functions of highlighting the authorial academic contribution, realizing academic identity,promoting cross-academic exchanges and achieving the function of self-promotion. Lastly, the authenticity, originality and uniqueness of academic writing can be effectively shown by properly using the language resources ofthe authorial voice construction in academic English writing.

This paper uses the Moran index to test whether there is spatial correlation between micro-finance and regional economic development by combining the panel data of 30 provinces in China from 2009 to 2018. Combining the Spatial Doberman Model 渊SDM冤to infer the correlation between micro-finance and regional economic development, and decomposition of its effects and objectively and accurately reflect the specific relationship between micro-finance and regional economic development. The results show that there is significant spatial dependence between micro-finance and regional economic growth. Micro-financial efficiency has a positive effect on the economic development of the region. It also promotes neighboring regions under the geographic distance matrix and improves the level of social fixed investment. It can promote the development of the local economy. The financial scale has a certain degree of restraining effect on the economic development of the region. The government financial support has a strong negative spillover effect. If spatial factors are not taken into account, the relationship between microfinance and regional economic development will be miscalculated.

At present, the increasing use of land in cities and towns has led to a sharp increase in the number of land-expropriated farmers. The contradiction between land expropriation and resettlement caused by the problem of employment and resettlement of land-expropriated farmers is becoming increasingly fierce. Solving the employment problem of land-expropriated farmers is in line with the actual needs; it can better promote the rationalization of the occupational structure of the land-expropriated farmers. Based on the field investigation data, this paper finds that the "pyramid" occupational structure has changed after land expropriation, and the trend of the transformation to the "olive" occupational structure is obvious. The occupational flow of land-expropriated farmers is frequent, and the occupational flow tends to some industries with low vocational skill and low entry threshold, and the employment quality is not high. Therefore, this paper holds that in order to solve the employment problems of land-expropriated
farmers, it is necessary to improve the employment policy and employment information system, introduce higher vocational colleges to participate in skills training, encourage the special employment docking of market enterprises, establish the "Internet plus" entrepreneurial support mechanism and improve the employment investigation and evaluation mechanism of landxpropriated farmers.

Abstract:On April 30, 1919, Dr. Dewey was invited to visit and speak in China. He stayed in China for more than two years. Through his travels and speeches, he was deeply impressed by the land of China and Eastern civilization.After reviewing Dr. Dewey's researches in China, we find that the route was the defect of previous studies. On the one hand, the provinces through which Dr. Dewey traveled were not complete; on the other hand, the order of his trip was not appropriate. In order to remedy the shortcomings of previous researches, this study not only clarified the 12 provinces and Beijing visited by Dr. Dewey, but also supplemented some historical information accordingly.
