本文由分析我国西北某些地区地壳上地幔电性结构特征出发,讨论了地震区地壳上地幔内的物理环境与地震活动关系方面的某些问题。並以1932年昌马大震震区深部热力学环境为例,结合前人某些岩石物理实验、固体破坏的实验和理论研究结果,讨论了在地震孕育过程中,在震源区内发生某些矿物脱水的可能性。 Based on the analysis of the electrical characteristics of the crust and upper mantle in some areas of Northwest China, this paper discussed some problems in the relationship between the physical environment and the seismic activity in the crust and upper mantle. Taking the deep thermodynamic environment in the earthquake area of ​​Chang-chang in 1932 as an example, and combining with the experimental and theoretical research results of some petrophysical experiments and solid-damage experiments of predecessors, we discuss some mineral dehydration in the seismic source area possibility.
