| 摘 要： | 对１９９１年４月和５月ＢＨ Ｖｉｒ的ＢＶ两色光电测光资料进行了分析，利用Ｗｉｌｓｏｎ－Ｄｅｖｉｎｎｙ带黑子的解轨程序对其进行了轨参量和黑子参量求解，结果表明：利用在次子星上加一个圆形低温黑子活动区的模型很好地拟合了实测光变曲线，同时解出了黑子的特征参量，即：黑子的温度、面积和位置。

| Abstract: | Phtoelectric observation in B V system of BH Vir were made at Yunnan Observatory from Apil to May 1991. After having analyzed the observations by Wilson-Devinney aproaches,we obtian the photmetric solutions of BH Vir.The results demonstrate that the light curves in 1991 can be fitted very well by the assumption of a cool,circular spot for active region on the secondary star.The parameters including the positon,the area and the temperature of the spotted region have been evaluated. |
