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。

不少学生对不定积分的计算总是掌握不好，究其原因，一是对不定积分的基本概念不清楚，二是对如何正确使用不定积分方法不清楚。1不定积分在计算中常用的概念1原函数的定义：若F′=f，则称F为f的一个原函数。

The indefinite integral formula of rational proper fraction function is worked out by utilizing the relation between derivation and indefinite integral, and indefinite integral is calculated by using derivative.

本文利用求导与不定积分的关系，得出了有理真分式函数不定积分公式，并利用导数计算其不定积分。

Firstly, the eigenvalue problem of a class of second order elliptic equation with critical potential and indefinite weights is considered. Then, using critical point theory, Trudinger-Moser inequality and the properties of the first eigenvalue, we prove the existence of a nontrivial solution for a class of nonlinear elliptic with critical potentialand indefinite weights in R~2. Secondly, we prove the existence of nontrivial solutions for a class of subcritical and critical elliptic systems with indefinite part in R~2 byusing a generalized linking theorem, Trudinger-Moser inequality and concentration-compactness principle.5. The existence of at least three weak solutions for discrete boundary value problem is established by using a three critical point theorem introduced by Ricceri.

首先，讨论了R~2中一类带不定权且含临界位势的二阶椭圆型方程的特征值问题，并借此特征值问题的第一特征值性质，利用山路引理及Trudinger-Moser不等式，证明了R~2中一类带不定权且含临界位势的非线性椭圆型方程非平凡解的存在性；其次，利用广义环绕定理，Trudinger-Moser不等式及集中列紧原理，得到了R~2上一类具有强不定部分的半线性椭圆型方程组在非线性项分别为次临界增长和临界增长情形下非平凡解的存在性。

In this paper, the linear indefinite equation , quadratic indefinite equation and the several special solution of indefinite equation are studied.

本文主要研究了一次不定方程、二次不定方程和不定方程的几种特殊解法。

For example, I speak to the students and the other another distinction, I have another first in the "an" and "other" Draw a vertical line. then inspire students under the Articles, The distinction between an ponder another and the other on the difference between through the analysis of two Articles 2 and indefinite pronouns between the common feature then from the indefinite article and the article migration between the different mentality out indefinite pronouns between two similar distinction.

例如，我在给学生们讲the other与another的区别时，我就先在another的&an&与&other&之间画一条竖线，然后启发学生根据冠词the、 an之间的区别去思考the other与 another之间的区别，即通过分析两个冠词与两个不定代词之间的共同特征，进而从不定冠词和定冠词之间的不同迁移思维出两个不定代词之间类似的区别。
