Chinahe having-been-used-for-50-year Boyd membrane diffusion Equation-In(1 - F) = R t can be deduced into F = kt through using Maclanrin expansion equation and the Lagerange remainders. The latter is a simple membrane diffusion equation;
which is available to judge if the exchanging course of the resin obeys the rules of membrane-diffusion mechanism more conveniently.;
