摘要
x方向采用有限元法,t方向用拉普拉斯的数值逆,求解一个偏积分微分方程的数值解,简便易行,而且该方法选择适当的求导阶数n可以达到所要求的精度。
In this paper, we apply the Inversion Technique for the Laplace Transform to discuss nunlerical solution of partial differential equation. This new method has been effectively applied in changing a proper n. This article presents the finite element method in the direction of x, but applies the inversion technique for the Laplace transform in the direction of t.
