| 英文摘要 | We have analyzed the radio light curves of PKS 1510-089 at 37 and 22 GHz from 1990 to 2005 taken from the database of the Metsahovi Radio Observatory, and find evidence of quasi-periodic outbursts. The light curves show great activity with very complicated non-sinusoidal variations. Using Jurkervich's method, the power spectrum method, and the discrete autocorrelation function to analyze these data, we have found two periods of p(1) = 0.92 +/- 0.04 yr and p(2) = 1.82 +/- 0.12 yr for the outbursts in PKS 1510-089. It is interesting to note that the results for two frequencies and three methods are almost the same and p(2) approximate to 2p(1). In addition, these results are in good agreement with the periodic deep flux minima of 1.84 +/- 0.1 yr ( half period similar to 0.92 +/- 0.03 yr) observed by us and other authors in the optical band in 2002, 2004, and 2005. |
