Space Materials Science in China:Ⅱ.Ground-based Researches and Academic Activities

Activities of space materials science research in China have been continuously supported by two main national programs.One is the China Space Station(CSS)program since 1992,and the other is the Strategic Priority Program(SPP)on Space Science since 2011.In CSS plan in 2019,eleven space materials science experimental projects were officially approved for execution during the construction of the space station.In the SPP Phase Ⅱ launched in 2018,seven pre-research projects are deployed as the first batch in 2018,and one concept study project in 2019.These pre-research projects will be cultivated as candidates for future selection as space experiment projects on the recovery of scientific experimental satellites in the future.A new apparatus of electrostatic levitation system for ground-based research of space materials science and rapid solidification research has been developed under the support of the National Natural Science Foundation of China.In order to promote domestic academic activities and to enhance the advancement of space materials science in China,the Space Materials Science and Technology Division belong to the Chinese Materials Research Society was established in 2019.We also organized scientists to write five review papers on space materials science as a special topic published in the journal Scientia Sinica to provide valuable scientific and technical references for Chinese researchers.

A causational analysis of scholars' years of active academic careers vis-à-vis their academic productivity and academic influence

Taking the scholarly activities of 73 doctoral program mentors working at the Chinese Academy of Medical Sciences & Peking Union Medical College(the CAMS &PUMC) as a sample of our investigative survey, we tried using such statistical methods as the analysis of variance(ANOVA), factor analysis and correlation analysis to compare the different characteristics of scholarship assessment of Chinese medical scholars as exhibited in their published papers in domestic and foreign journals. Our research findings show that citations per paper and A-index are more suitable for assessing the highly accomplished senior Chinese medical professionals(e.g. academicians) for their domestic and international scholarship attainment. In contrast, the m-quotient is not deemed appropriate to assess their academic influence both at home and abroad. Upon our further analysis of 6 evaluative indicators, we noticed that these indicators might be applied in two different aspects: One is from the viewpoint of Chinese scholars' academic influence at home, which has been evaluated mainly from the perspective of 'total' amount and 'average' amount of both publications and citations. The other is from their academic impact embodied by the means of documents retrieved from the Web of Science, which is mainly assessed from the two viewpoints of publications and citations. It is suggested that the accumulated time-length of a given scholar's active engagement in professional practice in a specific subject area be taken into consideration while assessing a researcher's performance at home and abroad.

FLOURISHING ACTIVITIES OF THE ACADEMIC DIVISIONS

In January 1984, the Academic Divisions of the CAS,which was established in 1955, held its fifth General Assembly after experiencing 30 years of trials and hardships, marking the beginning of a new period of flourishing development.Ten years passed between the fifth assembly and the seventh one,which was held in June 1994.It was in this decade that the Academic Divisions gradually assumed the practice of the international science community according to the domestic situation and international convention by making clear the nature and functions of the Academic Divisions and of their Members, renaming Division Mem-
