phase portrait

基本解釋

For the given parameters, the quantitative and qualitative analyses to the phase portrait and motion circle of the nonlinear free vibration are dealt with.
對(duì)給定參量的非線性自由振動(dòng)的相位圖特性、振動(dòng)周期等進(jìn)行了定量及定性研究。
The calculation result indicates that the pseudo-phase portrait to the utmost extent reflects the internal essential characteristics of original complicated system.
計(jì)算結(jié)果表明：偽相圖在極大程度上反映了原復(fù)雜系統(tǒng)的內(nèi)在本質(zhì)特征。

In the forth chapter,using the way of the phase portrait bifurcation analysis,we study kink-like wave solutions and antikink-like solutions of the F-W equation. The exact explicit parametric representations of those solutions are obtained and the numerical simulation is made.
第四章,利用相圖分析的方法,研究了Fornberg-Whitham方程的類似扭波解和類似反扭波解,給定參數(shù)值,求出了解的精確表達(dá)式,畫出其圖形。
