Optimizing the supply and demand structure of rural science popularization is the key to the good development of rural science popularization practice. In the context of the comprehensive promotion of rural revitalization, modern agricultural industries are developing rapidly, and new agricultural organizations and new farmers have generated a lot of new demands for science popularization, which poses a strong challenge to the rural science popularization work system operating in the traditional supply mode at this stage. Based on the preliminary in-depth rural research and village-based interviews, this paper summarizes the four major new demand directions of rural science popularization：talent, platform, resource, and mechanism demand. From the supply and demand model of rural science popularization, we explore the current situation of its supply and demand matching and the main influencing factors and propose four optimization paths worthy of attention in the next step, such as deepening the science and technology commissioner system, establishing a socialized collaborative science popularization service platform, attaching importance to grassroots science and technology demonstration, and building a characteristic science popularization mechanism according to local conditions.

It is an inevitable choice for the modern science and technology museum system to provide high-quality science popularization services to the public through establishing socialized mechanisms for collaboration, as well as broad participation from social forces is to be mobilized, to effectively integrate science popularization resources. An examination of the socialized collaborative practices of different components in the science and technology museum system is conducted by utilizing systems theory, synergetics, and social capital theory as analytical tools. On the base of the formation mechanisms of multi-subjects coordination in the science and technology museum system, the development strategies can be drawn as follows：attracting multiple subjects in the construction of the science and technology museums, developing financing channels for the mobile science and technology facilities, improving the structure of the social collaborative platform in the digital science and technology museum, strengthening internal and external linkage mechanism, and building evaluation mechanisms for social collaboration, with the hope to provide a reference for the construction of the science and technology museum system and the path exploration of a widely socialized science popularization pattern.

A museum visit is a basic form of informal learning, while "fatigued visitors" or "fatigue of visitors" has always been a hotly debated topic in museum studies. As a well-known phenomenon, museum fatigue has attracted scholarly attention since the early 20th century. By systematically reviewing the literature on museum fatigue at home and abroad, this paper starts from the concept and causes, uncovers potential factors that may impact fatigue, and summarizes the methods, improvements, and limitations of the existing research in measurement and evaluation. On this basis, combined with the essential features of science and technology museums, several valid paths are provided to alleviate museum fatigue, including building healthy environments, optimizing cognitive mode, and establishing interactive dialogue. Research on museum fatigue is of positive significance for promoting the management and utilization of museum resources.

As the dual roles of educators and researchers, university teachers can play a unique position in popularizing scientific knowledge. This paper aims to explore the influencing factors of university teachers' willingness to popularize science to achieve the purpose of motivating them. Based on summarizing the path of college teachers' participation in science popularization and the incentive elements of science popularization willingness in the existing research, it puts forward the hypothesis that the working environment, science popularization resources, personal cost and satisfaction incentive will influence college teachers' willingness to popularize science. A questionnaire survey was conducted on 94 teachers from the state key laboratories of eight universities on Xueyuan Road through the mail survey and the accidental sampling survey. The hypothesis was verified using multiple linear regression analysis. The research results show that science popularization resources can have a positive significant impact, personal costs can have a negative significant impact, and working environment and satisfaction incentives do not significantly impact university teachers' willingness to popularize science education. This paper provides informative suggestions to enhance the willingness of university teachers to popularize science from increasing investment in science popularization, constructing incentive mechanisms for science popularization and developing resources for science popularization in universities.

Evaluation of science popularization professional title is the main symbol of the academic technical level and professional ability of science popularizers, which plays an important role in stabilizing the talent team and stimulating their enthusiasm. Taking the first batch of science popularizers who participated in the professional title evaluation of "Library Materials Series (Science Communication) " as the research objects, using questionnaires and semi-structured interviewing, this study analyzes the satisfaction of the participants and the hidden problems in this professional title evaluation from three aspects：evaluation index, evaluation process and evaluation service. The results show that there are still some problems. Although the professional title evaluation of science popularizers in the non-stated sector has been solved, the proportion of participants from these sectors is very small. And then, the propaganda channel is more traditional and does not fully conform to the current habit of obtaining information. Next, the participants' satisfaction with "evaluation standard" and "fair and justice sense" is not ideal. Once again, the evaluation method of representative works is not specified in detail, which is not conducive to the participants' grasp. Finally, there is room for improvement in the content and methods of expert questioning. In view of above problems, this study puts forward some countermeasures, such as increasing publicity to allow more science popularizers to participate in professional title evaluation, making evaluation standards closer to the reality of science popularization and reflecting differences, refining evaluation methods according to evaluation indexes, and optimizing defense process of "representative achievement", to ensure the diversification of participants, objectification and moderate transparency of indexes, diversification of evaluation methods, and realization of scientific scoring.
