| 摘 要： | 本文提出不稳定导热问题的一种新的有限差分格式。这种格式根据所取时间、空间步长及边界条件确定相应的温度加权因子。这样给出的差分格式与C-N格式计算量相同,但准确性却明显提高,并且是无条件稳定的。

| Abstract: | This paper presents a new finite difference scheme for unsteady heat conduction in which the weighted factor for temperature should be determined according to the size of the time step,the spatial mesh size and the boundary conditions. This difference scheme has high accuracy and is unconditionally stable. |
