The Best Disturbed Iteration for Inverse Problem of the Dispersion Coefficient in Water Quality

摘要

The parameter identification inverse problem is a kind of important practical problem in many science fields. The method was established in this paper that on basis of function approach and Tikhonov regularization method, used operator identifies disturbed iteration method and linearization technology. The method called the best disturbed iteration method. The inverse problem of the dispersion coefficient in water quality was solved in the paper. The results of numerical simulation show that the method has a higher accuracy and a quicker convergent speed. And it is stability well, then worth of practical application.
