When we study the homoclinic orbits of the cqs equation, the quintic term is a perturbation
在討論cqs方程的同宿軌道時，五次非線性項被作為nls方程的擾動項。 -
In this case, we establish the persistence of invariant manifolds for certain perturbation of the cqs equation under even periodic boundary conditions
在這種情況下，我們對方程作了一些相平面分析，並得到了在擾動之後不變流行的保持性。 -
In chapter 2, we discuss the existence of homoclinic orbits for a perturbed cubic - quintic nonlinear schrodinger ( cqs ) equation with even periodic boundary conditions
第二章研究三次?五次非線性schr （ ? ） dinger （ cqs ）方程同宿軌道的不變性。 -
At the same time, cqs has the advantages such as excellent fame, powerful technical base and familiarity with the local humanity, geography and economy
而另一方面， cqs設計院擁有良好的聲譽，雄厚的技術力量，以及對本地人文，地理，經濟的熟悉等優勢。 -
The exterior envirement factors include politics, economy, society, culture and technology. then analysis focuses on cqs ' s competitive environment in local market with a five - forces model
在外部環境因素分析時，先從政治、經濟、社會、文化方面進行了宏觀環境分析，然後採用五力模型重點分析了cqs設計院的競爭環境。 -
Cqs is ongoing such a critic period. on the one hand it is facing the low - price competition from home rivals, on the other hand it has to fight against overseas eci companies with the advantages on capital, technology and management
Cqs設計院就處于這樣內外交困的關鍵時期。一方面，面對本土競爭對手的低價競爭，另一方面又面臨海外知名設計公司挾資金、技術、管理等優勢的強勢擠壓。 -
If the quintic term lies in the first terms, the unperturbed system is a quintic nonlinear schrodinger ( qnls ) equation and the cqs equation is not a near integrable systems, it only can be considered a perturbation of hamiltonian system
若五次項置於主項位置，即未擾動系統是一個五次非線性schr （ ? ） dinger （ qnls ）方程，此時的cqs方程不再是近可積系統，而僅是一個hamiltonian系統的擾動。 -
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，我們在常值平面上對擾動和未擾動系統進行相平面分析；然後利用奇異擾動理論討論不變流形的保持性，並給出不變流形的纖維表示；藉助于未擾動系統的可積結構和melnikov測度，我們得到了三次?五次非線性schr （
