The second surface integral calculation is a difficulty and key content of higher mathematics. The second curved surface integral, also known as sitting target surface integral, it said the physical significance of the steady flow of incompressible fluid flow to the surface side of the flow. The second kind of surface integral calculation problem is a comprehensive calculus problem, involves the surface side and the normal vector, partial derivative of function of many variables, double integral and triple integrals, the first kind of curved surface integral and gauss formula, and other knowledge.This article, we respectively from two traditional calculation method and an innovative method to calculate the direction of generalizations about the second type of surface integral calculation method, and combined with typical examples illustrate the use of different methods, easy to master by the techniques of.
