我们给出了一年多来对BVRI波段14个BLLac天体的监测结果。7个震源表现出短时间尺度变化，5个震源表现出大幅度的中时间尺度变化。讨论了10个BLLac天体存在相对论束流和吸积盘的证据。
We present the results of monitoring, over a period of 1 year, a sample of 14 BL Lac objects in BVRI bands. Seven sources exhibit short time-scale variability, and five sources exhibit medium time-scale variability with large amplitude. The evidence of relativistic beaming and accretion disks for 10 BL Lac objects is discussed.
