Designing General Economical Anticorrosion Pump

This article explores the corrosion mechanism of pumps and based on its analysis. research and experiment the tenability of the economical anticorrosion pump is explored farther, then designing general economical anticorrosion is put forward hereafter.

The iteration complexity is O(nL) , and the number of arithmetic operations per iteration is bounded by O(n 3) ,where n denotes the number of variables,and L is the import length.
