本文分析了影响近震震级M_2精度的因素.用计算和多次迭代的办法,计算出了近震震级M_L的起算函数在辽宁地区的矫正以及辽宁台网16个台站的校正值.同时又对辽宁台网限幅震级进行了多亢回归分析,并对结果进行了数学检验.我们认为:在地震发生限幅的非正常情况下.可以参考本文给出的统计公式计算地震震级.
In this paper, the factors that affect the accuracy of near-Earthquake magnitude M_2 are analyzed. By means of calculation and multiple iterations, the corrections of the initial function of M_L in Liaoning Province and the correction of 16 stations in Liaoning Province are calculated. We have carried out a multi-regression analysis on the amplitude of amplitude of Liaoning station network and conducted mathematical tests on the results.We think that in the abnormal situation of amplitude limiting of earthquake, the magnitude of the earthquake can be calculated by reference to the statistical formula given in this paper.
