Changing to the braking condition is the main cause of the train's longitudinal jerk.

制动工况变换则是导致列车冲动的主要原因。

Based on given electric current and Pulse Width Modulation (PWM) controlling system, the feedback process under each braking condition is studied.

以电流给定，脉宽调制(PWM)调压调速系统为例，研究各种制动状态下的能量回馈过程。

You should see if then braking mechanism and the engine are also in good working condition.

您应该看到，如果然后制动机制和发动机也保持良好的运行状态。
