invariant plane meaning in Chinese

不变平面

First , we take the analysis of phase - plane on the invariant plane for the perturbed and unperturbed systems . next , we applied the singular perturbation theory to establish the persistence of invariant manifolds , as well as the " fiber represent at iones " of these manifolds . finally , by using the global integrable theory of the unperturbed system and melnikov measurement we obtai n the existence of homoclinic orbits for the cqs equation under the generalized parameters conditions
首先，我们在常值平面上对扰动和未扰动系统进行相平面分析；然后利用奇异扰动理论讨论不变流形的保持性，并给出不变流形的纤维表示；借助于未扰动系统的可积结构和melnikov测度，我们得到了三次?五次非线性schr (
