任何解释地震发生过程的模式,必须要能说明各种与孕震有关的前兆观象。目前,膨胀—扩散模式在解释波速比的变化方面是比较成功的,但是对地壳的各种类型的形变、地温的变化、震源机制解中主压应力轴的转向或变化、发震构造型式等都不能在此模式中求得答案,因此,有必要提出更合理的模式来解释上述现象。 Any model that explains the process of earthquakes must explain the various precursory phenomena associated with seismology. At present, the expansion-diffusion model is quite successful in explaining the changes of the wave velocity ratio, but various types of deformation of the crust, such as the change of geothermal temperature, the steering or change of the principal compressive stress axis in the focal mechanism solution, the types of seismogenic structures Can not find the answer in this mode, therefore, it is necessary to put forward a more reasonable mode to explain the above phenomenon.
