震源孕育模式中的应力-化学腐蚀过程和宇宙线的调制作用

THE STRESS-CHEMISTRY CORROSION IN THE DEVELOPING EARTHQUAKE MODEL AND THE MODULATING EFFECT OF THE COSMIC RAY ON EARTHQUAKE SOURCE

摘要:

在临近大地震前,震源过程和前兆现象存在着一定的时间关系。本文从组合模式出发,利用断裂力学的应力一化学腐蚀理论来讨论临近大震前的震源过程和外因时震源过程的调制作用。在诸外因当中,为了研究宇宙线对地震的影响,本文具体分析了1965-1979年宇宙线μ介子强度变化的功率谱,首次得到了在所有周期分量中,准九天周期占有优势的结果。最后列举了宇宙线调制地震前兆的几个实例,并讨论了宇宙线对地壳中不稳定物质如过热液体暴沸的触发作用。

Abstract:

It is necessary to study physicochemically process and its precursors because the crust media and the earthquake process are very complex. Before an impending earthquake there is time dependence between the earthquake source process and its procursors. That could be interpreted from the viewpoint of slow crack propagation by stress-chemistry corrosion in fracture mechanics.
