    Hu Xiaowen Tan Xingye Chen Riyan Wu Baoyu

    Abstract:This paper applies quantitative and qualitative content analysis methods to analyzing 134 university museums at home and abroad from five aspects: spatial distribution, visitor perception hot spots, integration of university/museum educational attributes, social functions of leisure/education, and influencing factors of emotional experience of educational learning. The result shows that the overall public evaluation of university museums at home and abroad is high. The positive affective factor in domestic university museums is the identity stimulating cultural self-confidence, while abroad ones are complete informatization, the improvement of peripheral services and perceived self-social status. The negative affective factors of Chinese university museums are inconvenience in visiting, improper management of exhibits, lack of safety management and low service standard. Meanwhile, low interpretation service quality and cost effectiveness are two main negative factors that affect the science popularization experience in abroad university museums.

    Ma Xi

It also makes consistent efforts to connect the museum’s collections to the history of science, the history of Tsinghua University, even the history of modern China. This paper makes an analysis and summary of origins and results of these researches, reflects the existing works, also makes preliminary exploration and prospect of the relevant methodology of scientific instruments history research in domestic science and technology museums.

    Wang Xiaolin

    Abstract:Paleontological Site Museum is a very important kind of natural history museum, which can truly record major life evolution events on the earth. Thus far, China has established many national geoparks focusing on paleontology, and built distinctive site museums in their important fossil sites, which has played a positive role in the protection of fossils and their sites. However, there are still some problems need to be solved,including natural weathering and effective protection of fossils. How to build a site museum that can display the glorious history of life on the earth, carry out popular science education, also effectively protect the fossil records of these major life events is a severe challenge we are facing now.

    Keywords:natural relics, paleontological site museum, fossil protection, popular science education

    RevisitingMuseumSocialFunctionsinthePerspectiveofMerton’sStructuralFunctionalismTheory

    Liu Sha

    Abstract:Robert King Merton, a structural functionalist sociologist, revised several popular hypotheses in early functional studies, namely, the hypothesis of integration of social functions, the hypothesis of universal functionalism, the hypothesis of necessity and the hypothesis of explicit functions. His researches provided important inspiration for the study of museum functions. According to his researches, each specific function is accomplished through different structural components of the social system; and it is necessary to consider the different functional influences of museums on different individuals, different subgroups and the broader social structure. The same function may be realized in various ways, and various factors related to each other in a social structure restrict the possible variation range of function substitution items and realization modes. The functional analysis of museums includes not only “positive function” and “explicit function”, but also “negative function” and “l(fā)atent function”.

    Keywords:museum, Robert King Merton, structural functionalism, functional analysis

    ThinkingandPracticeontheCharacteristicDesignofNaturalHistoryMuseums’ExhibitContent

    Jiang Hao Hu Sheng

    Abstract:The natural history museums often have some difficulties in the characteristic design of exhibit content. The scarcity of natural collections leads to the lack of the basis of the characteristic design. The lack of high-level planning talents with academic support ability, the lack of interdisciplinary talents and the huge natural knowledge system lead to the absence of depth and width of characteristic of content design. The deep-rooted traditional concept of exhibition leads to the lack of positive breakthrough in the educational function of exhibition content design. Measures to address these problems includes: analyzing collection characteristics and undertaking systematic supplementary collection, combining the regional natural geographical features, integrating interdisciplinary advantages and training the interdisciplinary talents, changing the traditional concept of exhibition, organically integrating educational functions to the exhibit content design, and etc..

    Keywords:natural history museum, exhibition, content design, characteristic, countermeasure

    TheDesignandDisplayValueoftheFourGreatArmillarySpheresinSongDynasty

    Tang Shenyu

    Abstract:The armillary sphere was the most important instrument of astronomical surveying, used for observing and distinguishing astronomical phenomena in ancient China. Now we can see exhibits of armillary spheres in many science and technology museums. However, the shape and structure of armillary sphere were not consistent; many transitions had been made during the long history. The armillary sphere in the Han and Tang Dynasties had more prominent function of demonstrating the structure of the universe. After the Song Dynasty, the observing function of the armillary sphere had begun to receive attention. The Four Great Armillary Spheres had been cast during the Northern Song Dynasty; each one was different from the others in many details. The four great armillary spheres in the Northern Song Dynasty focused on the simplification of structure and the improvement of measuring accuracy, and directly promoted the invention of the abridged armillary sphere made by Guo Shoujing in the Yuan Dynasty. Nowadays, the diversified display of the armillary spheres of the Song Dynasty not only reflects the latest research results, but also reflects the new perspective of modern people on the science and technology of the Song Dynasty.

    Keywords:armillary sphere, astronomical instrument, Song Dynasty
