In the same of average power, peak power and duty cycle constant, pulse width is the primary parameter which affects the kerf width.

在相同的平均功率、峰值功率和脉宽比下，脉冲宽度是影响切缝宽度主要参数。

So a method for matching parameter of HEV based on the vehicle duty cycle is proposed. In this paper, the works carried out as follows.

行驶工况对汽车性能的影响很大，因此，研究基于行驶工况法对混合动力汽车的参数匹配的影响具有很好的理论和实践意义。
