摘要
文中先提出一个恒等式，并在有关文献基础上给出了新的高阶微分方程组的求解法，进而论证了所给方程组的可积性，获得了一系列结论。
Firstly, this peper puts forth an inentical relation, then it applies for the method of solving solutions of newdifferential equation set of high-order based on relative references Moreover, it gives evidence of the integrability of givenequation set and draws a series of conclusions.
