| Abstract: | The long-term variabilities of PKS 0735+178 in UBV bands have been shown and discussed by means of the methods of period analysis and correlation analysis. The results show that there is a strong variation period of 14.42years in B band, the variations in optical UBV bands are closely correlated with no delay, and the spectral shape is associated with the brightness of the source. This revised version was published online in July 2006 with corrections to the Cover Date. |
