本文的目的,是力争应用有关震沅物理的知识,去逐步解决电、光短临前兆的机制问题,以及依此寻找各前兆的内在联系.进而将其应用到临震予报上去.超声波趋前于声波在地壳中,应力集中点往往在承受很大的单向应力时,产生扩容过程.水饱和及岩石的摩擦强度下降.在存在摩擦的条件下,岩石的蠕动与运动加速,导致岩体微破裂.在微破裂过程中,最初频率可能高些.按应力集中、微破裂至断裂的发展顺序,超声波趋前于声波(人的耳阀能产生共振的).并于临断裂
The purpose of this paper is to strive to apply the knowledge about shocking physics to gradually solve the mechanism problems of electricity and light and short-term impending signs, and to find the internal relations of the precursors. Then apply it to the Prosecution Report. Before the acoustic wave is in the crust, the stress concentration point often undergoes a process of expansion when it is subjected to large uniaxial stress. The water saturation and the frictional strength of the rock are reduced. Under the condition of friction, the peristaltic motion and acceleration of the rock cause the rock to accelerate. Body micro-rupture. In the micro-rupture process, the initial frequency may be higher. In the order of stress concentration, micro-rupture to fracture, ultrasonic waves tend to be acoustic waves (people’s ear valves can resonate).
