| 摘 要： | 以遥测地震台网大量的观测资料为基础，拟合了限幅时间t的对数与近震震级ML的线性回归关系，结果显示二者有很好的相关性，相关系数为0．967，标准误差为0．2121。检验证实结果是可靠的。得出当台网记录限幅时，采用这种方法快速估算震级进行速报是可行的结论。

| Abstract: | Based on a large number of observation data from the telemetric seismic network, the linear regression of the lasting time t of truncated amplitude with local earthquake magnitude M L was made. The result shows that both t and M L correlate to each other quite well.The coefficient of correlation is 0.967 and the standard error is 0.2121. The test with the data of many earthquakes shows that the result was reliable. The conclusion is that this method used in quick report for estimating truncated magnitude of the telemetric seismic network records is effective |
