| 摘 要： | 引入不变嵌入概念求解移动边界问题，并以冰的熔化过程为例进行计算。用不变嵌入法求解，既将是复杂的移动的边值问题转变为初值问题，用简单的数值方法方便地处理熔化过程中自然对流的边界条件和初期凝固，并减少了计算时间，本文将计算结果与冰球熔化的实验作了比较。

| Abstract: | Invariant imbedding method is applied to solve moving boundary problem. It converts a complicated movingboundary problem into an initial value problem. In the paper ice melting processing has been calculated. Free convection boundary condition and initial solidificationin in the ice melting processing have been treated conviniently by numerical technique,and calculating time decreases. The results of calculation are compared with those of melting experiment of a ice-ball. |
