摘　　要：量规函数是用来校准补偿地震波随距离的衰减的,本文对上海区域台网的量规函数进行重新计算,同时和全国通用的量规函数加以对比,观察是否需要对上海区域量规函数进行修正。并使用统计平均震级和ML震级定义两种方法来计算量规函数。The calibration function is used to calibrate and compensate the attenuation of seismic waves with distance.We calculate the calibration function of the Shanghai regional network,and then compare it with the national calibration function.We use two methods to calculate the calibration function,one with the statistical average magnitude and the other with the ML magnitude definition.
