| 摘 要： | 本文发展了一套计算机自动证认、交叉比对的技术,应用于1989年9月至12月间北京天文台60/90cm施密特望远镜的CCD测光资料及GSC星表,由二个系统的V星等资料,在6个平方度内找到5颗变星;利用二个系统B颜色带宽的不同,进行发射线星系巡天,在3个平方度内找到15个致密核发射线星系.并讨论了本方法用于光变天体、包指数反常天体、位置移动天体、发射线天体巡天的可能性.

| Abstract: | A technique has been developed for computer automatic search for variable stars and emission line galaxies. The method applied to the COD photometric data taken with the BAO 60/90 cm Schmidt in September to December 1989. Combining with the GSC V mag. data, 5 variables were found. Using the defference in B-bandwidth in CCD and GSC, we found 15 emission line galaxies, most of which are compact and nuclear-dominated galaxies. The capabilities of using this technique to search for the variable stars, moving objects, unusual color index objects and emission line objects are discussed |
