摘要
所讨论的一类重要的初、边值问题,其数值解利用传统方法效果不佳.通过特征差分和降低奇性的技巧给出一种有效解法,数值实验表明,其精确度很高.
In this paper,the authors deals with a kind of important inital boundary value problems which is not perfectively solved by some traditional processes.By the technique of decreasing the singnlarities and difference along the characteristic,the authors gets a efficentive numerical method.Numerical results show that method is a high accuracy algorithm.
