摘　　要：利用云南天文台射电四频率 ( 1 .4 2 ,2 .1 3,2 .84和 4 .2 6GHz)同步观测系统于 1 989.1 2～ 1 994 .1和北京天文台射电频谱仪 ( 2 .6～ 3.8GHz)于 1 996.1 1～1 998.5的观测资料 ,仅对太阳和射电爆发中 4 0个事件作了一个初步的统计分析 ,就微波低频段的快速精细结构在耀斑中产生的相位作了一个探索 。The statistical analysis of 40 solar radio events which were obtained with Radio Synchronous Observation System at four frequencies(1.42, 2.13, 2.84, and 4.26 GHz) in Yunnan Observatory during December 1989 to January 1994 and the spectrometer(2.6～3.8GHz) in Beijing Observatory during November 1996 to May 1998 is made in this paper.The phase of the radio FFS occurred at low frequency band of microwave(long centimeter to short decimeter wavelengths)in flare is approached.The regularity of the phase of flare occurred radio FFS in this frequency range is found.
