摘要
给出了微分方程M(x,y)dx+N(x,y)dy=0复合型积分因子的定义,得到了复合型积分因子存在的充要条件和计算公式.
The auther gived the definition of complex integrating factor about differential equation M(x, y)dx + N(x, y)dy = 0, then obtained the necessary and sufficient condition of the existence of complex integrating factor and its calculating formula.
