【摘要】：為了穩(wěn)定求解平衡擴散速率色譜模型,采用有限差分法建立了其迭代求解的隱式差分方程,討論了其穩(wěn)定性與方程誤差,通過仿真計算考察了該差分格式的計算誤差,并通過甘草苷與甘草素的分離實驗進行驗證。結果表明:該差分格式在線性及非線性體系下無條件穩(wěn)定,計算誤差小,準確度高;在非線性體系下,甘草苷與甘草素的計算色譜流出曲線與實驗流出曲線吻合良好。
[Abstract]:In order to solve the equilibrium diffusion rate chromatographic model stably, the iterative implicit difference equation is established by using the finite difference method. The stability and error of the equation are discussed. The calculation error of the difference scheme is investigated by simulation. The separation experiment of glycyrrhizin and glycyrrhizin was carried out. The results show that the difference scheme is unconditionally stable in linear and nonlinear systems, with small calculation error and high accuracy, and the calculated chromatographic efflux curves of glycyrrhizin and glycyrrhizin agree well with the experimental effluent curves in nonlinear systems.
