| 摘 要： | 从位场理论的观点讨论了场和源的概念,建议将“场兆”改称为构造前兆,将“源兆”称为震源前兆。文中还分析了震源体与各种前兆观测方法探测的深度,并根据地磁与重力观测方法不同的物理基础和地质基础,指出震磁效应对于研究震源前兆的特殊意义,文中还介绍了１９７６唐山地震观测到震源前兆的部分实际地磁资料。

| Abstract: | In this paper, the conception of " field" and " source" was discussed from the viewpoint of potential field. It is suggested that the " field precursor" be replaced by the tectonic precursor and the "source precursor" be replaced by the precursor of earthquake source. The depth of earthquake source and exploratory depth from various precursory methods are analyzed. According to the different physical and geological foundation of gravitational and geomagnetic methods, it should be pointed out that the seismo-magnetic effect is of significant in study of precursor of earthquake source. A part of geomagnetic data of the earthquake source observed during Tangshan earthquake with M = 7.8. 1976 are introduced in this paper. |
