摘　　要：提出了一个解二维抛物型方程初边值问题的简单实用的显格式，证明了其截断误差阶是，稳定性条件是且，其中。In this paper, a simple practical explicit three-level differencing scheme for two-dimensional parabolic partial differential equation is considered. For the discussed scheme, the order of local truncation error is, and the stability condition is and max, where
