| 摘 要： | 利用青海省数字地震台网记录到的玉树地区2006年5级强震群地震和2010年7．1级地震的数字波形资料，计算了这2次地震序列应力降值，并进行了对比，发现应力降值在中强余震前都出现较明显的变化，同时随着地震的衰减，应力降值也逐渐减小。

| Abstract: | Using digital wave data to calculate stress drop of Yushu earthquake with Ms7.1 in 2010 and earthquake sequences with MsS. 0 in 2006 recorded by Qinghai seismic network. By making comparison of them, the stress drop has significantly change before moderately strong aftershock and dramatically changed after earthquake. |
