教学目标 Course Objectives
通过本课程的学习，使得学生了解产生力电耦合现象的几种主要机制，包括动电效应、压电效应、压磁
效应以及感应电磁效应，明白这几种不同的力电耦合机制的基本原理，了解力电耦合在地震电磁学研究
中所起的重要作用。
Upon completing the course, students will obtain the basic knowledge on the fundamentals of several
mechanisms (including electrokinetic effect, piezoelectric effect, piezomagnetic effect, and motional induction
effect), which are responsible for the coupling between mechanical and electromagnetic wave-fields. Students
also will understand the important role of the mechanical-electromagnetic coupling in the study of earthquake-
related electromagnetic phenomena.
