摘要
有限元法实质上是变分问题的一种数值解法,是物理问题的通用计算方法.本文从应用角度出发,讨论光纤问题中的有限元法.结合具体问题研究,得出可供编写计算机程序的数学模型.
Essentially,the finite element method is a numerical techni- que for the variational problems,which is a general approach to physical problems.This paper discusses the finite element method for the optical fibre problems starting from viewpoint of application.The study in conjunction with the concrete pro- blems will provide computer program with the mathematical models.
