摘要
提出了一族关于二维热传导方程的二层显式差分格式，当截断误差０（τ２＋ｈ４）（或０（τ＋ｈ２））时，稳定条件为（或ｒ≤１），它们都优于其它同精度的显式差分格式。
A class of two-level explicit difference schemes for solving two-dimensional heat conduction equation are presented.The stability condition is r(or r≤1) when the truncation error is 0(τ2+h4) (or 0(τ+h2)),they are all better than the other explicit difference schemes of the same accuracy.
