| 摘 要： | 某些BL Lac天体的光变曲线显示的周期性通常被认为是天体中心存在的双黑洞模型的轨道运动所引起的,文章在这一假定模型的基础上,认为在BL Lac天体PKS 0735 178中心也可能存在着双黑洞并利用其光变时标及光变周期分析它的中心结构,通过计算得到主黑洞和次黑洞的质量分别为1.7109M⊙和2.88107M⊙以及它的轨道参数和双黑洞系统的寿命.

| Abstract: | Some BL Lacertae objects show a periodic behaviour in their light curves that is often attributed to the orbital motion of a central binary black hole systems. On this basis, it is consider there is a binary black hole system perhaps in the central of PKS 0735 178 and its central structure is analyzed by using its time-scale and periodicity of the light variability property of BL Lacertae object PKS 0735 178 in optical B-band. By calculating, the masses of the primary and secondary black holes are 91.710Meand 72.8810Me respectively. The distance between two black holes and their lifetime is measured. |
