Chinese ancient literary works contain a large number of scientific and technological factors, including the observation and recording of astronomy and geography at that time, the understanding and thinking of natural changes, the generalization and description of technological processes, and the imagination and prediction of the mysterious future. Through the study of ancient myths and legends, folk ballads, novels and operas of these four types of popular literary works, which contains the analysis of the specific technological content and function of science education, it helps to enhance the interest and effectiveness in the popularization of science and technology, and to gain a new understanding of the value of the ancient Chinese literary works.

Promoting the combination of scientific research and science popularization, encouraging and guiding scientists to participate in science popularization, especially in popular science writing, is one of the initiatives in the field of science communication in China. Based on questionnaire survey and panel interviews, this research tries to analyze the current situation of scientists' engagement in popular science writing, their problems and requirements. According to the investigation, Chinese scientists widely believe that it is their responsibilities to participate in popular science writing and they show strong willingness to that. However, they don't actively engage in popular science writing accordingly, and even if involved in it, the form is quite traditional. Interest and social responsibility act as the main motivation for them to participate in popular science writing. The lack of time and energy, imperfect assessment and incentive mechanism are the main obstacles. And on the demand side, the scientists expect a better policy environment and incentives, as well as the corresponding training and services. Based on the aforementioned research, the paper puts forward relevant countermeasures and suggestions on inspiring scientists to participate in popular science writing.

Low-carbon popular science education serves as an important way to build a low-carbon and sustainable society engaged by the public. The paper explores the current situation, the daily low-carbon behaviors and the expectations about the low-carbon popular science education of primary and middle school students in counties of Guangxi Zhuang Autonomous Region. The results found in the paper reveal that: Firstly, due to a lack of the low-carbon popular science education in counties, the students rarely take part in the low-carbon popular science education. The students in primary and middle schools don't understand most of the low-carbon vocabulary. The low-carbon popular science education is mostly carried out in schools and networks. The most popular ways of the low-carbon popular science education are teachers' lecturing and reference books reading, while the least popular way is visiting the low-carbon popular science education venues. The most impeding factors for low-carbon popular science education are that there no activities about popular science and that the students are burdened with busy and heavy study tasks and homework. Secondly, the judgment of the low-carbon behaviors of primary school students is not high. The low-carbon behavior of junior high school students is better than that of the primary school students. The low-carbon behavior of high school students is the best among them. Thirdly, the students in primary and middle schools expect that low-carbon popular science education should be conducted more frequently. The most expected ways are the popular science games and the visits to the popular science venues. The countermeasures and suggestions of low-carbon popular science education in counties have been proposed in the last part, which provides the empirical evidence and reference to the low-carbon popular science education conducted in the counties.

Featured with immersive experience, Dome theater is a multi-purposefacility for science education and has been becoming the main type theaters in the science museums in China. Through summarizing the origin and development of the dome theater, it is obvious that digital dome theater embodies the dual function of films releasing and science education on astronomy. The data of dome theaters in science museums between China and the United States are comparatively studied in the paper, including quantities, sizes, shows, educational activities and amount of audiences. The findings in the research reveal that albeit the scale of big dome theaters in China is largely the same as that of the U.S., the amount of audiences and popularity are less and lower. The main reasons contain three aspects. Firstly, the function and orientation of Chinese dome theater is oversimplified which results in lacking educational activities. Secondly, the production of films and shows is insufficient and the price of rent is high. Thirdly, the formats of dome system are not standardized which brings about the difficulty in film releasing on different dome theaters. In order to have the current situation changed, it calls for three aspects to be promoted accordingly. The advice to dome manager is that astronomy education and the real-time show is the key point for dome activity and film production. The suggestion to the related department is to formulate standardized guidance.

Biographies of scientists of modern China are encountering multiple dilemmas largely due to the conflicts between realities and dramas of biographical literature, the differences between natural science and humanities and social science, and the checks and balances of scientific popularization, historical research, ideological propaganda and the like. This paper analyzes the afore-mentioned multiple dilemmas. Biographies of scientists of modern China can combine science with drama, history and literature only when scientists and biography authors have good cooperation. Researchers of history of science and technology bear important responsibility in this process. Moreover, the development and improvement of biographies of scientists of modern China hinges on the enhancement of scientific literacy of all citizens in China.
