摘要 运用热平衡积分法(HBIM)和改进的热平衡积分法(RIM)求解了一维两相融化问题,根据精确解比较了2种方法所得融化参数的相对误差.结果表明:在固定温度边界条件下选取二次函数近似时,热平衡积分融化参数的相对误差较小,且随着Stefan数的增加,2种积分结果的误差都在减小(Ste<1). The two - phase refined integral method （RIM）. melting problem is solved by using The obtained relative errors of the heat balance integral method （HBIM） and melting constant from the two methods are compared based on the analytical solution. It shows that the melting constant calculated using HBIM is more ac- curate than that of RIM, under the constant temperature boundary condition when using the quadratic function, and the errors of the two methods decrease with increase in the Stefan number（ Ste 〈 1 ）.
