摘　　要：用近似法分析了有耗媒质中非对称电偶极的激励场,得到一个场和焦耳热的简单的解析表达式。与传统的对称型半波振子公式相比较,其下端导体的电流分布表达式相同,当下端导体为四分之一波长时激励近场表达式相近。结合典型储油层给出一些计算结果,对电磁波采油技术有参考价值。An approximate method is used to analyse the excited fields with a non-symmetrical dipole in lossy media and simple analytical expressions about the fields and joule heat are obtained. These expressions are compared with the formulas of traditional symmetrical half-wave dipole. Some calculated results are given for a typical oil reservior, which will be useful for the electromagnetic wave oil recovery technique.
