| 摘 要： | 对在1981-2000年世界上所发表的和中国学者所发表的有关恒星与恒星系统的论文作统计发现：此期间世界上这一领域的发展较平稳，而我国的发展快速．这反映了改革开放后，我国基础学科研究大有进展．从各分支所占的比重和发展来看，我国在恒星与恒星系统的研究与世界同期有几乎相同的分布，因此总体上我国在这一领域的发展基本正常．当然有些分支发展较快，如有关超新星及其遗迹、星际介质和恒星形成区、化学丰度的研究等，这和一些较强的研究团组形成有关；在双星研究方面，我国则与世界发展一致，双星研究始终是恒星研究领域的重点；而在世界范围内较突出的关于银河系的研究，在我国却相对较弱．恒星和恒星系统这一研究领域20年的论文数统计显示，我国学者所发表的论文只占世界总论文数的1．3％，虽然在最后5年有大幅上升，但也只占2．0％，这与我国IAU会员数所占比例相比是偏少的．就世界整体而言，恒星领域的研究进展与整个天文学领域相比是较慢的，显然这与一批能做深空探测和高能波段观测的设备投入有关．因此，除了对恒星及恒星系统领域作统计分析外，对整个天文学领域各大分支作分析可能对制定今后我国天文学发展计划更有利。

| Abstract: | Based on the statistics of the paper on stars and stellar systems published in domestic and international journals, it is found that between 1981 and 2000, the progress of these two fields developed more rapidly in Chinese astronomical community than those in abroad, which reflected the fast progress in Chinese scientific researches after the reformation. Some branch fields in stars and stellar systems had made more significant progress based on their active research groups, such as supernovae and their remnants, interstellar media and star formation regions as well as stellar chemical abundance. The binary systems, which is one of the key fields in stellar systems, had synchronously with international progress, while the research on the Galaxy was relatively poorer in China.
In these 20 years, the fraction of total number of the paper on stars and stellar systems published by Chinese astronomers was only 1.3% in the world, and it shows an obvious increasing in the recent 5 years with the fraction about 2.0%, which is still less than the fraction of international IAU members in China. Due to the development of deep-sky and high energy observing instruments, the progress in stellar research is relatively slowed down compared to the other fields in astronomy. Besides analyzing the field of stellar and stellar systems, we also need to analyze the other major branches in astronomy so that a feasible development plan can be made for Chinese astronomy in the future. |
