Riccati方程化成变量可分离方程的几个条件及相应的通积分

Several Conditions Turning Riccati Equation into an Equation with Separable Variable and Corresponding General Integral

用不变量的概念给出一类Riccati方程化成变量可分离方程从而可积的几个条件及相应的通积分 。

By using the concept of invariant,this paper gives several conditions turning Riccati equation into an equation with separable variable,which is integrable,and corresponding general integral.As well the resufts in the relatives references are include into this paper.
