摘要
采用积分近似法对第三类边界条件下环形空腔内相变介质的凝固问题进行求解，得出计算凝固总时间的关系式，分析讨论内外管径比η＊和Ｂｉ数对凝固总时间的影响。
n this Paper, integral method was employed to obtain approximate solution for the solidification process in a concentric annulus with boundary conditions of the third kind. The equation for calculating the total time of solidification was obtained.The effect of radii ratio η*and Bi number on the total time of solidification was also analyzed and discussed.
