摘　　要：回顾了中国用小望远镜进行的一些科研项目,如小行星的天体测量和测光观测,近地天体的观测和天然行星卫星的天体测量观测。介绍了小行星和近地天体轨道的测定,以及行星/月球历表的编制。简述了天体测量标准区的建立,从射电源光学对应体推算光学和射电参考架的联系,双星轨道的测定,以及星团成员星自行的测定。提出了改进GSC2.3的新项目,其中包括消除星等差和南天恒星自行的系统差,以及减小偶然误差,并建议加入新的观测作为POSS和SERC项目第三历元的观测资料。Several programs, such as astrometric and photometric observations of asteroids, observations of NEOs and astrometric observations of the natural planetary satellites, with small telescopes in China are reviewed. The orbital determinations for asteroids and NEOs as well as development of planets/lunar ephemeris are introduced. Studies on establishment of astrometric calibration regions, linkage between optical and radio reference frames from optical counterparts of radio sources, orbital determinations for binaries and determinations of the proper motion for membership of stellar cluster are briefly described. The new program on the improvements for GSC2.3 such as eliminating the magnitude equation and systematic error in proper motion in the southern hemisphere as well as decreasing the accident error, adding new observations as data at third epoch of POSS and SERC projects etc. is presented.
