Scientific paper

In this paper, a new method - TDCF (Time Delay Correlation Function) method, is introduced to calculate the time delays of multi-band data in blazars. This method is adopted to analyze the time delays of the radio source 0316+413 and the correlation analysis of the other seven blazars. The results show that the light curve of 0316+413 at 4.8 GHz lags about 410 days behind that at 8 GHz, the light curve at 4.8 GHz lags 440 days behind that at 14.5 GHz and the light curve at 8 GHz lags about 30 days behind that at 14.5 GHz. It is very reasonable to use the TDCF method to carry out the correlation analysis of the time delays of the other seven blazars.
