When the locomotive is traveling at a constantspeed or idling, the battery rather than the diesel engine can power the motor.
当火车头在相对恒定速度下前进或者空转时，这时电池就为马达提供能量，柴油发动机不工作。

Biological information processing mechanism and constant pressure network technology were researched to control the rotational speed of hydraulic motor.
运用生物信息处理机制和恒压网络技术进行马达速度控制。
