针对二维三温耦合热传导差分方程组的特点，给出并比较了块G-S算法和ICCG算法.数值结果表明，ICCG算法的收敛速度比块G-S算法的收敛速度可以快数千倍.并且，在二维激光黑腔靶耦合的数值计算中，如果能够实现向量化计算，使用ICCG方法将会大大提高数值模拟的计算效率.

In view of the special needs for systems of difference equationsof 2-D heat conduction coupled three-temperature,the block G-S algorithm and the ICCG algorithm are presented and compared.Numerical results show that the ICCG algorithm is thousands times faster than the block G-S algorithm.Furthermore,in 2-D numerical simulation of laser hohlraum target coupling,the ICCG algorithm will raise greatly computational efficiency if it can realize vectorzation operation.
