无限稀释活度系数 meaning in English

dilution activity coefficiet
infinite dilution activity coefficient

Abstract : the model parameters for uniquac and nrtl equations are obtained by using the infinite dilute activity coefficients of a component at several temperature and the nonlinear regressive technique . the vaporliquid equilibrium ( vle ) data calculated by using the parameters for uniquac or nrtl equation is agreement with that from vle experiment
文摘:通过一个组分在不同温度下的无限稀释活度系数，利用非线性回归确定了四氢呋喃1 , 4丁二醇、水1 , 4丁二醇二元体系的uniquac 、 nrtl溶液模型参数.用所获得的两溶液模型参数对三元气液平衡数据进行理论推算,并与实测的三元气液平衡数据进行比较,发现两结果比较吻合
