摘　　要：以南北地震带为例,通过对1920～2011年全国有记录的各种震级地震资料的整理统计,利用投影分析,计算出宏观震中与微观震中之间的偏移量,研究震级和偏移量之间存在的非线性衰减模型,并对模型拟合的有效性进行了分析。结合我国地震测震技术发展的阶段性特性,探索研究了时间对偏移量的影响。Illustrated by the North-South Seismic as an example,by sorting and statistic all kinds of the seismic data in different magnitude that have been recorded in China since 1920,we calculated the offset by using projection a—nalysis and studied the nonlinear damping model between magnitude and offset,and analyzed the validity of fitting by this model.Combined with the periodic characteristic of the development of the seismic technology in China,we studied the influence of time on offset.
