The effect of salt concentration in mobile phase on theretention of solute in RPC has been investigated by using stoi-chiometric displacement model of solute retention (SDM) and hasbeen concluded that this effect is due to the change of the molefraction of water in the mobile phase. These experimental resultsobtained in this study shows the expected one from the SDM. i. e.,there is a linear relationship between logk' and log1/[D_0]_(H_2O). Theseresults from the SDM are also Compared with that from Solvophobictheory...

The effect of salt concentration in mobile phase on theretention of solute in RPC has been investigated by using stoi-chiometric displacement model of solute retention (SDM) and hasbeen concluded that this effect is due to the change of the molefraction of water in the mobile phase. These experimental resultsobtained in this study shows the expected one from the SDM. i. e.,there is a linear relationship between logk' and log1/[D_0]_(H_2O). Theseresults from the SDM are also Compared with that from Solvophobictheory which explaines the linear relation of logk' to the saltconcentration, Cs, in mobile phase due to the linear relationshipsof both logk' and Csalt to the surface tension of the mobile phase.This study pointed out that the latter case may not be suitable.

本文以反相色谱中的溶质计量置换保留模型研究了流动相中盐浓度对溶质保留行为的影响,指出这种影响是由于盐的加入降低了水在流动相中的摩尔分数。实验证明了这一理论模型所预计的结果,即logk’与水的摩尔分数倒数的对数—log(1/[D_0]_水)有线性关系;同时与疏水溶剂化理论有关的“盐的浓度与logk’间的线性关系是由于前者与溶液中表面张力间的线性关系所致”的论点做了比较,证实后者的提法是欠妥的。

In this paper, based on the structure preserving model, the topological energy function and the method of the potential energy boundary surface of power system transient stability analysis which all have been developed in recent years, an effective algorithm for deriving the practical dynamic security regions (PDSR) of multimachine power systems is proposed. One hyperplane of the PDSR is approximated by least squares using the critical points selected with reference to orthogonal tables. Such PDSR not only can simulate the interested parts of dynamic security regions well, but also can be expressed and used easilly.

Based on the stoichiometric displacement model of adsorption (SDM-A) the stoichiometric displacement model of retention (SDM-R) in LSC has been derived directly. It was found that the equation derived by this model is identical to that in RPO and comparison was mode among equations of various models. It was shown that SDM-R may be used for both monolayer and multilayer adsorption. The parameter J, in this model, is a constant for PRC with which one can distinguish LSC from RPC.
