Scientific paper

In this paper, the compiled long-term optical and infrared measurements of some blazars are used to analyze the variation properties, and the optical data are used to search for periodicity evidence in the lightcurve by means of the Jurkevich technique and the discrete correlation function (DCF) method. The periods are found in the range of 1.5 to 19 years. The short time scales are used to estimate the central black hole masses which are found in the range of (3.8 - 130)×107Msolar for the gamma-ray loud blazars. Some discussions are presented.
