The Results of Radio Synchronous Observations at Four Wavelengths During the Solar Cycle 22 in Yunnan Observatory

In this present paper the observational results during December 1989 to April 1993 by using the synchronous observational system of solar radio emission with high temporal resolution at four wavelengths (1.42,2.13,2.84 and 4.26 GHz)are briefly presented. Total 102 radio bursts are primarily anlysed. The time profiles of several classes of typical events are reveaiad. It shows the importance of observations with the high temporal resolution.
