摘要
本文主要研究了a、b值的变化对震级特征图的影响。当a、b值的变化幅度不太大时,仍然可从震级特征图上识别出最小均匀震级等震级阈值;当a、b值的变化达到相当的幅度后,震级阈值点变模糊了。
This paper mainly studied the influence of the variation of a, b values on the magnitude characteristic chart. When the varied amplitude of a, b values is not too great, the isoseismal threshold value of the minimum uniform magnitude can still be recognized from the magnitude characteristic chart; after the variation of a, b values reached a certain amplitude, the threshold point of magnitude becomes obscure.
