本文给出了12个X射线选BL Lac天体5年的光学（BVRI）监测数据。主要结果是：（1）IE 0317+178在约1.93天的时间尺度上显示出0.53mag的R带变率。(2)在H 0548-322的V带中记录到5分钟内0.58 mag的变异性。我们的研究结果将有助于理解XBL和RBL之间的关系。(C)1996年美国天文学会。
The optical (BVRI) monitoring data covering 5 years for 12 x-ray-selected BL Lac objects are presented in this paper. The main results are: (1) IE 0317+178 has shown a variability of 0.53 mag in R band on a time scale of about 1.93 days. (2) A variability of 0.58 mag within 5 min was recorded in the V band for H 0548-322. Our results would be valuable to understand the relation between XBLs and RBLs.
