非线性振子 meaning in Chinese

nonlinear oscillator

For small displacement u , the oscillator is a duffing - type cubic non - linear oscillator , while for large displacement u , the oscillator approximates to a linear harmonic oscillator
所谓达芬谐波振子是指当位移远小于1时，系统可化为三次非线性振子，而当位移远大于1时，该系统则化为线性谐波振子。
In chapter 4 , the bifurcation of the complex nonlinear oscillator of van der pol - duffing - mathieu ' s is studied and the common bifurcation property of the oscillator in the situations of nonresonance , principal resonance , ultraharmonic resonance and non - subharmonic resonance is revealed . the bifurcation of strongly nonlinear oscillator is also explored in this chapter
第四章对非线性振动中最常见的vanderpol - duffing - mathieu复合非线性振子的分岔性质进行了系统的研究，发现了该复合系统在非共振、主共振、超谐共振和非1 2阶次谐共振情况下具有相同的分岔特性。
