	在常微分方程课程学习中，积分因子的求解是一个难点问题，本文利用不变代数曲线法求解积分因子与逆积分因子，解决了两类微分方程的可积性问题。<br />
In the course of ordinary differential equations, finding integrating factor is a very difficult problem. In this paper, we will give a method to solve integrating factor or inverse integrating factor by invariant algebraic curves; the integrability of two differential systems is solved.
