| 摘 要： | 通过震级-频度关系资料和地震台站分布资料的分析,发现震级-频度关系曲线在震级较小的一端的分布特征反映了地震能量分形和地震台站状况交互作用的结果,从而在地震序列分析中,考虑不同历史时期地震台站的状况及其影响,是一项必不可少的工作.

| Abstract: | From the analysis of the-apparent magnitude-frequency relations for relativelysmall earthquakes in different periods and the distribution of seismological sta-tions,it is pointed out that the apparent magnitude-frequency relations for smallearthquakes are determined both by the fractal characteristics of the earthquakesand by the distribution and sensitivity of the seismological stations,and there-fore it is necessary to consider the distribution and sensitivity of the seismologi-cal network in the analysis of seismicity and historical seismological records. |
