摘　　要：本文基于经典的牛顿冷却定律,采用微分方程、迭代法以及最小二乘法线性拟合分析等数学方法,建立了新的数学模型。该数学模型可以较好地分析自然冷却和循环冷却两种条件同时作用于氢同位素分离柱时的冷却曲线,预测冷却所需要的时间,进而指导冷却条件的选择。Based on the classic Newton’s law of cooling and combined with the mathematical methods such as differential equation, iterative method, least square method and linear fitting analysis, a new mathematical model is established. The mathematical model can be used to analyze the cooling curve of hydrogen isotope separation column which was cooled by both natural ventilation cooling and circulating cooling, predict the required cooling time and guide the selection of cooling conditions.
