Since this frame of reference-the earth –is rotating, motions that would be straight in a stationary frame of reference appear curved to the observer on earth.
由于参照系—地球—是旋转的，所以在静止参照系中应是呈直线运动，在地球上的观测者看来就成为曲线运动。
Based on the analysis of traditional compensation methods, a method compensating the dead-time in a synchronous rotating reference frame is proposed, which fits for general-purpose inverters.
