应用人工爆炸地震,农田抽水试验,地震地磁测量以及航磁△Ta资料反演成果,探索震磁关系。结果发现：（1）地磁场强度短周期变化数量不等;（2）实际观测的前兆磁异常比实验室测试的数据偏大。表明地震前兆异常不仅存在,而且这种地磁短周期变化是由多种物理效应叠加的结果。作者认为,在应力、应变等因素确定的条件下,温度的影响是构成震磁效应的重要因素,因此研究地壳磁性结构及磁性层底介面即居里等温面的空间分布特征,对潜在震源区的判定是有意义的。

Based on the explosion seismology,pumping test on farmland,seismomagnetic measurement and reversion results of ΔTa aeromagnetic data,the seismomagnetic correlation has been discussed in this paper.One of the results is that the short-period geomagnetic intensity varied differently;Another result is that the practical measured value of the precursor magnetic abnormal data is higher than in the laboratory.The results have showed that those earthquake precursor abnormalities indeed exist.And the magnetic short-period variation is the result of many physical effects superposition.The author considered that when the stress and strain are determined,temperature has been an important factor for causing seismomagnetic effect.Therefore,it is meaningful to do the research on the crust magnetic structure and the bottom interface of magnetosphere,which is the spatial distribution characteristics of curie isothermal surface.
