摘要
详尽阐述了寻找短周期变星的数据处理过程.所运用的搜索方法是计算其星等光变幅度是否大于其它同种亮度星的光变幅度,即若一颗星的光变幅度大于大多数正常的同种亮度星的相应的σ的一定倍数(>3σ),则认为该星是变星的最初候选者.
In this paper a method of the discovery of short variable stars is stated in detail. The procedure used to find candidate variables is based on the selection of stars with light curves showing large dispersion as compared with other stars of similar magnitude. That is , a star is selected as a variable candidate if it presents a larger deviation （〉3σ）in its light curve compared with that of other star of similar magnitude.
