摘　　要：根据对鬼星团中Ｊｏｈｎｓｏｎ测光标准星的观测，我们研究了北京天文台６０ｃｍ望远镜直流光电光度计ＵＢＶ测光系统的转换方程．应用该方程推算了对三颗变星观测得到的ＵＢＶ星等，讨论了所得光变曲线的精度。A study of transformation equations for photoelectric photometry was carried out,based on the observations of Johnson standard stars in Praesepe using the 60cm reflector equipped with the DC photoelectric photometer at Beijing Astronomical Observatory,Chinese Academy of Sciences. The transformation equations were applied to the reduction to the UBV photometry for three variable stars. The light curves we derived and their standard errors were compaired with the results from the differential observation.
