Science popularization is an important way and form to transmit the innovative culture to society. This study first analyzes the connotation and characteristics of innovative culture，and then clarifies the logic of forming an innovative culture. It also explores the ways in which science popularization can help promote the construction of an innovative culture. The study sorts out the mechanisms for science popularization participating in the construction of an innovative culture at different stages，and constructs a planar mechanism framework by introducing social interaction theory and science communication models. Against the backdrop，three suggestions were thus put forward，i.e.，the construction of a narrative system for science popularization towards the goal of building a world leader in science and technology，the improvement of the effectiveness of a value identification-oriented communication system，and the enrichment of diversified media strategies with dialogue as the focus. These suggestions will provide references for the use of science popularization to promote the construction of an innovative culture.

The construction of standard system for science and technology museum underlies the implementation of the standardization work，which is of great significance for the high-quality development of science and technology museum. However，existing literature rarely explored the standard system of science and technology museum systematically and comprehensively. After a full consideration of the current development status，future development trend，and standardization needs of science and technology museum by employing the standardization theories and methods，we proposed the principles of building the standard system，i.e.，comprehensiveness，practicality and moderate foresight，and built a three-dimensional model of standard system，i.e.，distribution field，standard level，and binding force of standard. The chart and diagram of standard system are mainly constructed from 7 distribution areas：basic general standard，facility construction，exhibition and education resource construction，service，operation management，information technology，and evaluation. Finally，based on the diagram of standard system，we put forward the countermeasures and suggestions for setting standards from two aspects，i.e.，the priority of the development of basic standards and urgent standards，and the consideration of the coordination of different levels of standards，for the purpose of providing reference for implementing the standardization work of science and technology museum systematically and programmatically.

Through the online questionnaire survey of 338 science and technology museums that have received free opening subsidy funds by the end of 2021 and the field investigation of some science and technology museums，we have a comprehensive grasp of the allocation，use，system construction，performance evaluation and supervision，and the effect of the policy about the national free open science and technology museums. The research results show that all regions highlight the importance of the free opening of science and technology museums，constantly strengthening institutional construction，and providing different levels of financial support. At the same time，they suggest that the supervising department should clarify the scope of expenditure of subsidy funds，take the exhibition and education area of science and technology museums and the annual audience number as the basic allocation factors of free opening subsidy funds，and appropriately consider the regional financial difficulties and performance evaluation results when allocating funds. Based on the above research results，this article puts forward some relevant suggestions for the clarification of the scope of free opening subsidy funds expenditure，the adoption of factor method for fund allocation，the encouragement of the construction of distinctive exhibits and exhibitions，and the strengthening of performance evaluation and supervision and management，which provides strong support for the drafting and promulgation of the“Management Measures for Free Open Science and Technology Museum Subsidy Funds”.

With the trend of vigorously promoting the participation of scientists in science popularization activities，how to assist scientists in improving the efficiency and effectiveness of science popularization has become a challenge faced by various countries. This research argues to draw on the experience of European science museums in assisting scientists in conducting science popularization activities. Based on interviews with the heads of education departments at five science and technology museums in Europe，and an analysis of the exhibition materials at these venues，this research delves into how these five venues support effective participation of scientists in science popularization activities through interactive exhibitions and educational resources. The results show that the European Science and Technology Museum effectively enhances the participation and effectiveness of scientists in science popularization activities through diverse display methods and professional training. These findings provide reference for China’s science and technology museums to establish diverse platforms for interaction and communication between scientists and the public，emphasizing the provision of science popularization ability training for scientists，and collaborating with scientists to promote the spread of scientific spirit. In addition，it is recommended to conduct more basic research and utilize the technological advantages of science museums to innovate the forms of science popularization activities and promote the inheritance and development of science and culture.

Social media has become one of the primary channel for the public to obtain emergency science popularization information. In the social media context，emergency science popularization on mainstream media may reduce the cost of obtaining and identifying emergency science information for the public and promote the public to make sense of the risk and respond effectively. This study uses manual and computer-driven content analysis methods to examine the content of science popularization messages in People’s Daily microblog during the Covid-19 epidemic. The results show that emergency science popularization on People’s Daily microblog was situation-oriented to satisfy the public information needs and relied on authoritative sources to ensure the contents accuracy and reliability. It interpreted risks objectively and corrected misinformation continually to promote public understanding of the disease. In addition，sufficient efficacy information was transmitted to provide reliable guidance for the public. The study also indicates that knowledge about treatment and authoritative sources were significantly associated with greater public engagement. Accordingly，this study further illustrates the importance and mechanisms of situational factors and authoritative experts in mainstream media’s emergency science popularization，and explores the possibility of public participation in the collaborative network of emergency science popularization in social media context.

The scientific community，an integral part of Sci-Fi films featuring disaster narratives，has been constructed as multiple images. As a key element in science communication，the images of the scientific community in films exert a tremendous impact on how accurately scientists，the public and mass media interpret its connotations. This study explores the image construction of the scientific community in Sci-Fi films from the perspective of comparative narratology. It starts with a survey of Western film history，focusing on the shifting roles of the scientific community，including a loosely-bound organization in name only，an old school hindering the advancement of science and technology，and an almighty savior. It then analyzes The Wandering Earth II，a great representative of contemporary Chinese Sci-Fi films，unveiling its imprints of Oriental culture as well as Chinese features. Based on this comparative study，it further points out that the images of the scientific community in films can boost the communication of scientific spirit and scientific ethics，strengthen the confidence of the human race as the determinant of historical progression，and provide valuable materials for the reflection upon and reconstruction of this community in the future.

The spirit of craftsmanship is the secret weapon to propel Germany’s industrialization and modernization. With the rise of a power country，Germany has taken a series of measures to cultivate the spirit of craftsmanship. In the field of vocational education，Germany has established a“dualism”vocational education system. In the field of science investigation and application，it has has developed a research and innovation system dominated by research—education—industry that combine industry，academia，and research. In the field of history and culture，it has a cultural atmosphere and historical tradition that emphasize rationality and science. In the field of Politics，The German government pays attention to the cultivation of the spirit of science and craftsmanship，and provides sufficient institutional guarantees and policy support. Currently，it is of great practical significance，for the development strategies of China’s creation，the National Science Literacy Action Plan，the Science and Technology Innovation National Construction Development Goals，and the“Made in China 2025”Plan，to refer to the measures and experiences of Germany’s spirit of craftsmanship cultivation.
