通过岩石蠕变实验，得到用标准线性固体本构方程拟合蠕变曲线比较合理的结论。对溧阳、南黄海地震的数据处理，发现应变释放曲线和蠕变曲线有相似之处，进而用标准线性固体来拟合应变释放曲线，求得弛豫时间和有关参数，计算出了地壳岩石介质的黏度为1018Pa · s。考虑到地区差异以及岩石圈黏度存在有明显的分层，而所用的地震震源深度又相对较浅，但得到的黏度数量级还是和有关文献相一致的。

Based on the creep experiment, the creep curve was fitted by constitutive equation of standard linear model. In the data process of Li Yang and Nan Huanghai earthquake, there is a similarity between stain release curve and creep curve. Fitting stain release curve by standard linear model, relaxation time and other parameters are got. By calculation, crust’s viscosity is about 1018 Pa·s. Considering the regional difference and difference of layers in the lithosphere and the hypocenters in this article are relatively shallow, so the order of viscosity is con?sistent with related literatures.
