同伦映射 meaning in Chinese

homotopic mapping

Using the homotopy mapping theory , a class of nonlinear problems were studied
摘要利用同伦映射理论，本文研究了一类非线性问题。
On the basis of analyzing spwm , it is studied that the method of solving shepwm ( selected harmonic eliminating pulse width modulation ) models by homopoty algorithm . the convergence of solutions of the gained homopoty equations is analyzed
在此基础上，重点研究了同伦映射解特定消谐脉宽调制( shepwm ： selectedharmoniceliminatingpulsewidthmodulation )模型的方法。
