  1. The recovery voltage contains power frequency component and low-frequency decaying component when transient fault occurs , and it only contains power frequency component when permanent fault occurs .

    瞬时性故障时,恢复电压由工频周期分量和非工频衰减分量组成,永久性故障时,恢复电压仅由工频周期分量组成。

  2. On the basis of the steady-state semi-empirical model of the tire and the concepts of the relaxation length and the effective slip ratio , a non-steady semi-empirical model to express the tire longitudinal-slip response to the low-frequency input of the transient vertical load and transient slip ratio was presented .

    在稳态半经验模型的基础上,根据松弛长度和有效滑移率的概念建立了能表达时变垂直载荷及时变滑移率低频输入下的轮胎纵滑特性非稳态半经验模型。
