新丰江水库6.1级主震前后(1961年2月—1975年3月)十四年间地震波速比的变化特点,冯锐曾作了分析研究,尔后尚未继续此工作。为此,紧接上述终止时间,从1975年4月至1983年12月九年间对该库地震波速比演变过程再予分析,以探索后期较强余震(M_s>4)发生前与主震前后期间,波速比变化是否存在着异同,并作进一步讨论。
Before and after the 6.1 magnitude Xinzangjiang Reservoir (February 1961 - March 1975) before and after the earthquake wave velocity ratio changes in the characteristics of Feng Rui had made an analysis and research, but has not continued this work. To this end, immediately following the above termination time, the seismic wave velocity ratio evolution of the reservoir was analyzed again from April 1975 to December 1983 to explore the correlation between the strong aftershock (M_s> 4) before and after the mainshock During this period, whether there is any similarities and differences in wave speed ratio changes is discussed further.
