This article has sorted out the data of indefinite integral concept in common use, and has analyzed the features of three methods of indefinite integral in common use: the first substitution method of integration, the second substitution method of integration, and integration by parts.

因为，(x2)′=2x，(x2+1)′=2x，(x2+2)′=2x，(x2+c)′=2x所以x2，x2+1，x2+2，x2+c均为2x的原函数。由此得出：一个函数若有原函数存在则有无数个原函数存在，且任意两个原函数之间相差一个常数。

So we need consider the effects of the earth curvature. In global integration, the requirement of the data coverage and the computation are comparative high. In this thesis, a moving coordinate system is used to overcome the effects of the earth curvature. And a differential calculation concept is proposed that assumes the difference of geoid calculated between the central point and its marginal point is constant when the integration area is far away from the central point.
