受现代统计物理学研究进展的某些启发,作者以极大的热情投入了大震前非稳态过程的研究,结果是非常令人鼓舞的。这里仅作简要报导。1.大地震发生前介质的应力应变曲线的非线性阶段是大地震前各种非平衡态前兆现象出现的基础。非线性阶段可以从测震学指标中得到。例如蠕变曲线的加速,小震频次的加速, Inspired by the progress made in modern statistical physics, the author, with great enthusiasm, devoted himself to the study of unsteady processes before large earthquakes and the results are very encouraging. Here only for a brief report. 1. The nonlinear phase of the stress-strain curve of the medium prior to the great earthquake is the basis for the appearance of various non-equilibrium precursors before the earthquake. Non-linear phase can be obtained from seismological indicators. For example, the acceleration of creep curve, acceleration of small earthquakes frequency,
