0類二次系統(tǒng)極限環(huán)的產(chǎn)生與消失 - Limit cycle problem of quadratic system n
0的極限環(huán)問(wèn)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(shù)及其周期解 - It's difficult to find quadratic system in a sentence. 用quadratic system造句挺難的
- 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(jiǎn)捷地推導(dǎo)出二次系統(tǒng)的前三個(gè)焦點(diǎn)量和鞍點(diǎn)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(wèn)題中的極限環(huán)的個(gè)數(shù)問(wèn)題及其在生態(tài)環(huán)境上的應(yīng)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(jié)果證明：使用描述函數(shù)法能夠簡(jiǎn)化該問(wèn)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(guān)于類二次系統(tǒng)的已知結(jié)果,在此文中我們系統(tǒng)分析了類二次系統(tǒng)當(dāng)= 0時(shí)其極限環(huán)的產(chǎn)生與消失的整個(gè)過(guò)程,并給出了一些新的拓?fù)浣Y(jié)構(gòu)變化,它們?cè)陬愊到y(tǒng)中是不會(huì)出現(xiàn)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(jīng)完成了二次系統(tǒng)極限環(huán)的有限性證明，但其證明過(guò)程中用到了涉及復(fù)域的il ' yashenko定理，從而給il ' yashenko定理一個(gè)初等的證明是本文的主要思想。
