Abstract:
The method of unitination of optimization technique and numericalanalysis method can efficiently be used to estimate the parameters in equa-tions without analytic solution in chemical engineering.A complex examp-le which was composed of partial differential equation,differential equati-on and algebraic equation was used to discuss this method.The resultsshowed that this method could be used to obtain the needed model para-metets accurately and rapidly,and could be widly used in chemical enginee-ring.
