- Creation and disappearance of limit cycles in quadratic system
0類二次系統(tǒng)極限環(huán)的產生與消失 - Limit cycle problem of quadratic system n
0的極限環(huán)問題 - The planar quadratic system with an invariant cubic curve has at most one limit cycle
類方程的極限環(huán)存在性的注記 - Sufficient and necessary conditions of existence of limit cycle for one kind quadratic system
一類二次系統(tǒng)極限環(huán)存在的充要條件 - On the reflective function and the periodic solution of the second order differential quadratic systems
二次微分系統(tǒng)的反射函數及其周期解 - The first 3 focus quantities and the first 3 saddle quantities are derived simply and quickly with the formulas for real planar quadratic systems
利用這一公式我們極其簡捷地推導出二次系統(tǒng)的前三個焦點量和鞍點量公式。 - At the end of this paper we talk about the question of the maximal number of limit cycles in quadratic system and some applied uses in ecological circumstances
在本文的最后略為涉及hilbert第十六問題中的極限環(huán)的個數問題及其在生態(tài)環(huán)境上的應用。 - The results prove that df could simplify the solve process and its shortcoming of restriction in approximately denotation , frequency unitary 1 and inapplicability in more commonly quadratic system are also shown at the same time
結果證明：使用描述函數法能夠簡化該問題的求解，但也暴露出其存在著近似表示，頻率歸1以及更一般二階系統(tǒng)不適用等方面的局限和不足。 - By using the known results of type quadratic system , we analyse thecreation and disappearance of limit cycles for type system as a = 0 , and obtainsome new topological structures of phase - portraits , which do not appear for type system
利用關于類二次系統(tǒng)的已知結果,在此文中我們系統(tǒng)分析了類二次系統(tǒng)當= 0時其極限環(huán)的產生與消失的整個過程,并給出了一些新的拓撲結構變化,它們在類系統(tǒng)中是不會出現的 - In this paper we will prove that quadratic system has at most finitely limit cycles . bamon claimed that he had finished the demonstration of the finiteness of limit cycles , but he used il ' yashenko theorem , which involves some knowledge of complex domain , so it is the main idea to give il ' yashenko theorem an elementary proof in this paper
本文將用純初等方法研究二次系統(tǒng)極限環(huán)的有限性，雖然bamon宣布已經完成了二次系統(tǒng)極限環(huán)的有限性證明，但其證明過程中用到了涉及復域的il ' yashenko定理，從而給il ' yashenko定理一個初等的證明是本文的主要思想。 - It's difficult to see quadratic system in a sentence. 用quadratic system造句挺難的
