摘　　要：采用函数迭代法,给出一个引理,提出三类新的高阶非线性常微分方程,反复利用函数的迭代使之转化为微分方程组的求解,再应用积分法,以获得原微分方程的通积分公式,从而论证了方程的可积性,直接运用通积分公式,使得求解相应方程的解的过程大为简化.In this paper, using the method of function iteration, a lemma was given, and three new types of higher degree nonlinear ordinary differential equations were presented. Using the method one and again the equations can be translated linear differential equation system and be solved. And then using the method of integral, general integral formula can be obtained, so that the integrability of original equations can be proved. Diretly using general integral formula, the proess of solving equations can be greatly simplified.
