Van der Pol振子稳定闭轨存在性的一种证明

A PROOF OF EXISTENSE OF STABLE CLOSE TRAJECTORY IN THE OSCILLATOR OF VAN DER POL

VanderPol方程是三极管电路的数学模型 .利用著名的Poincare Bendixon环域定理 ,给出了VanderPol振子在正阻尼 (μ >0 )

Equation of Van der Pol is the mathematical model of an audion circuit. Authors propose a new proof of existense stable close trajectory in the oscillator of Van der Pol when damp value is positive (μ>0).
