教学目标 Course Objectives
本课程为地球物理学等相关专业研究生的选修课。地球物理学以对地球介质中的各种物理场特征的研究为
基础，其中电磁场是地球物理中广泛应用的方法之一。本课程主要讲述电磁场在地球介质中传播和分布的
理论基础以及电磁方法在地球物理学中的主要应用。通过本课程，学生将掌握以下内容：
（1） 地球电磁场基本理论及地球介质中的电磁场分布；
（2） 全球电磁感应模型及应用电磁感应推断全球电导率分布；
（3） 地磁起源理论及全球地磁参考模型；
（4） 电磁方法在地震机理研究及地震监测中的应用。
This is a specialized course for graduate students in Geophysics and other related areas. Geophysics is based on
studying different physical fields within the Earth’s interior. One of the widely used fields in Geophysics is the
electromagnetic field. This course aims to introduce essential principles of the propagation of electromagnetic
fields within the Earth’s interior and major applications of the electromagnetic methods in Geophysics. Upon
completing this course, students should be able to grasp the following contents:
(1) Fundamental theory of geo-electromagnetic field in the Earth;
(2) Global EM induction model and global electric conductivity model;
(3) Origin of the Earth’s magnetic field and reference models of geomagnetic fields;
(4) EM methods in earthquake studies.
