摘要
针对有限差分法在使用中的一些缺点,提出了一些有效的改进措施,并进行了必要的公式推导,得到了相应的便于应用数值计算的结果,使原来编程难以处理的边界线和内部媒质分界线有了较方便的处理方法,这将使有限差分法在工程计算和科学研究中发挥更大的作用。
In this paper, aiming at disadvantages of the Finite Difference Method, a new method of dealing the boundary is introduced. By deducing the necessary expressions, the useful results are gained that can be used conveniently. Since being easy to deal with interface and boundary of the solving region, the new way makes the FDM become useful again in the engineering calculation and research.
