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.
在分析了传统死区时间补偿方法的缺点之后，提出了适合于通用变频器的基于旋转坐标变换的死区时间补偿方法。
Three dimensional annular seal flow field was simulated quasi-steadily with computational fluid dynamics (CFD) method in a rotating reference frame. The Rotordynamic coefficients were calculated.
应用计算流体力学(CFD)方法对转动坐标系下的三维环形密封流场进行了准稳态数值模拟，在此基础上进行了转子动力系数的计算。
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。
