摘　　要：为研究Be/X射线双星的光度变化,正利用北京天文台60cm望远镜进行UBV光电测光。本文叙述一年来的观测。并结合观测结果对观测和归算方法作了若干讨论,我们主要采用较差测光附加标准星观测以便转换到标准系统。消光计算时考虑零点漂移和可能与大气质量平方的线性关系:m-m_0=k′X+k″c+k_2X^2+k_tt+q。标准系统与观测系统的星等和色指数采用线性关系转换。The observations for studing the Be/X-ray binaries light variation were made with the UBV photoelectric photometry system at the 60cm reflector of Beijing Astronomical Observatory. in 1990. In this paper, the preliminary results are described with emphasis on the discussion of the method of observation and data reduction. Differential photometry and standard star observation are used to transform the data to the standard system. In the extinction calculation, the zero shifting and the probable linear relation with the square of the air mass were also considered: m-m_0=k′X+k″c+k_2~″X^2+k_1t+q. The linear relation was assumed between the standard and observation system.
