摘要

We present results derived from a monitoring program of a sample of FR-II type radio quasars. The variabilities detected in their densely covered light curves, which have being gathered over a period of more than 9 years, are analyzed with statistical methods (LSP and WWZ). We found no statistically significant, strictly coherent periodicities in our data.
