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。
In this paper, the effects of two different interpolation methods, namely linear interpolation and Lagrange interpolation on the convergence rate of the model calculation, are discussed in the nonlinear multicomponent liquid chromatography rate model. The results show that the use of Lagrange interpolation method can greatly improve the computational efficiency, converge quickly in the case of low finite element number.
