摘要
本文运用数值分析方法，探讨了在粘弹性介质中的剪切产热不稳定性的详细动力学过程，并结合实际俯冲板块情况，分析了深源地震的形成机制，结果表明，由于粘滞损耗产热而形成的剪切产热不稳定性是深源地震可能的发生机理之一。
In this paper, we study the dynamic process of the shear heating instability occured in a Maxwell body using the finite difference method and discuss the implication for the origin of deep focus earthquakes. The result shows that the shear instability due to the viscous hearing during subduction of plates is probablely one of the mechanism of deep focus earthquakes which mainly occur in subducted zones.
