对二维三温热传导方程组提出一类分数步有限差分格式。
A kind of fractional steps finite difference scheme is introduced to solve two dimensional equations of heat conduction with three temperature.
由于二维三温热传导方程具有很强的非线性特性，因此采用全隐格式对该方程离散后，所得非线性代数方程组的求解将变得非常困难。
As 2-d 3-t heat conduct equations are discretized in a fully implicit method, it is very difficult to solve the nonlinear algebraic equations obtained due to strong nonlinearity.
