常微分方程是现代数学的一个重要分支,是表达自然规律的一种自然的数学语言.常微分方程有很多种形式,但其大都不可求解.其中,全微分方程可以通过观察法,公式法等进行求解.如果微分方程不是全微分方程,这就需要积分因子,然而求积分因子无固定方法可循,因此,本文在介绍了全微分方程与积分因子的概念以及相关定理的基础上,归纳总结了求解微分方程的积分因子的方法.力图通过观察法,公式法等方法对全微分方程解法进行探索,进而讨论积分因子的存在的充分必要条件,提出利用观察法、公式法、分组求积分因子法求积分因子,以便顺利求微分方程的通解,从而使利用积分因子法解微分方程得到广泛的应用

只好用谷歌了Ordinary differential equations is an important branch of modern mathematics, a natural mathematical language to express the laws of nature. Ordinary differential equations in many forms, but its mostly non-Solving Among them, the differential equations can by observing the law, the formula methodsolved if the differential equation is not full-differential equations, which requires integrating factor, however, the quadrature factor fixed method to follow, therefore, this paper introduced on the basis of the full differential equation with integrating factor concepts and theorems, summarizedintegrating factor methods for solving differential equations. trying to observation, formula and other methods to explore the full-Differential Equation, and then discuss the necessary and sufficient conditions for the existence of the integral factor proposed by observing the law, the formula method, grouping the quadrature factorof quadrature factors, in order to smooth and differential equations the general solution, so that the integral factor method for solving differential equations has been widely used【求采纳,如果答案不尽如人意不能采纳 请看在回答的份上 点击一下右下角大拇指“赞同”送我1分 谢谢 =3=】
