压磁效应不一定是震磁关系的唯一可能机制.本文认为,从我国邢台地震区地震与地磁变化观测的事实出发,用压磁效应很难解释震磁之间的关系.因此就提出震源区由于岩石介质的微破裂、膨胀的液体扩散引起地磁场变化的设想,并称此种设想为“‘膨胀’磁效应”. 在简化了的假定条件下,初步计算表明,用此假设讨论地震区地磁场变化的空间分布与实际观测的结果较为符合.有一些检验震例.
The piezomagnetic effect is not necessarily the only possible mechanism of the relationship between magnetism and magnetism.This paper argues that it is difficult to explain the relationship between magnetism and magnetism by using the piezomagnetic effect based on the observation of the earthquakes and geomagnetic changes in Xingtai earthquake region in our country, Due to the micro-cracking of the rock media, the expansion of the expanding liquid causes the assumption of a change in the geomagnetic field and calls this assumption “an ’expanding’ magnetic effect.” Under simplified assumptions, preliminary calculations show that this assumption The spatial distribution of changes in geomagnetic field is in good agreement with the actual observation results.
