| 英文摘要 | The observation data in the B band for BL Lacerate object PKS 0735+178 during 19701998 from twenty two publications have been compiled into a light curve. The light curve shows that PKS 0735+178 is very active and exhibits very complicated non-sinusoidal variations. Using both Jurkevich's method and Power spectrum method to analyze these data we have found two periods of 5.26+/-0.98 years and 1.24+/-0.05 years for the outbursts in PKS 0735+178. It is of interest to note that the results of the two methods axe the same (almost). In addition, these values are in good agreement with the results found by Smith et al.(47) and Webb et al.(61) We also apply the binary black hole model to explain the central structure of this object and obtain the masses of the primary and secondary black holes axe 1.7 x 10(9)M(circle dot) and 2.88 x 10(7) M-circle dot respectively. It should be monitored in future to obtain more data for further analysis to test the hypothesis. |
