Once the call returns for the current time step, you clear the forces applied to the objects from the last step, and then get the current position and Angle of your dynamic body.
一旦此调用针对当前时间步长返回，就可以清空上一步长施加到这些物体上的力，然后获得动态物体的当前方位和角度。
As for the problem the high current and the vibration of the torque, the double closed loops which include the current and power factor Angle are worked out.
对于电动机起动需要控制起动电流和转矩震动的问题，采用双闭环的控制方案，即电流闭环控制和功率因数角闭环控制。
You could answer the question in the context of your current job but you'd be better off approaching it from the Angle of the job for which you are applying.
你可以从现在的工作切入来回答这个问题，但是最好从你申请的工作这个角度入手。
