| 摘 要： | 本文讨论了非线性多组分液相色谱速率模型求解过程中两种不同的插值方式即线性插值和拉格朗日插值对模型计算结果收敛速度的影响。结果表明,使用拉格朗日插值方式能大大提高运算效率,在低有限元个数的情况下很快收敛。

| Abstract: | Two interpolation methods, which are linear interpolation method and the Lagrange interpolation method, are compared for calculating the rate model of multi-component nonlinear liquid chromatography. The results show that when the Lagrange interpolation is used the efficiency of calculation is elevated significantly. And the calculation converges quickly at low finite element number. |
