一、前言以短周期地磁异常研究为基础的地磁测深方法,近年来得到异乎寻常的发展和广泛应用,美国、加拿大、日本、澳大利亚和欧洲许多国家都进行了大规模地磁测深的研究,他们主要利用台阵和永久性地磁台的观测资料。观测结果的解释和应用是多方向的,不仅应用于大地构造和深部地球勘测方面,而且也有不少作者应用于地震活动性和地震予报的研究领域。特别是近年来,人们从深浅 I. INTRODUCTION The geomagnetic sounding method based on the study of short-period geomagnetic anomalies has been unusually developed and widely used in recent years. Many countries in the United States, Canada, Japan, Australia and Europe have carried out large-scale geomagnetic survey. They mainly make use of the observation data of the array and permanent geomagnetic stations. The interpretation and application of the observation results are multi-directional, which not only applies to the tectonics and deep earth exploration, but also has many authors applied to the field of seismic activity and earthquake prediction. Especially in recent years, people from different shades
