摘　　要：利用近似积分解法求解第二类边界条件下一维有限域内的熔化问题 ,得到满足精度要求的隐式解 .引入熔化系数 ,在一定参数范围内对隐式解进行数值求解 .所得结果与前人计算结果相比 ,具有更广泛的适用性 .Approximate integration is employed to solve the problem of heat transfer in melting of the boundary conditions of constant thermal current on one side and constant temperature on other side in the finite region. By taking the melting coefficient to analyze the approximate integration, the results presented can be used without any additional conditions.It's more suitable than the previous.
