2. active flux model 本质上是一种磁场定向坐标系下的模型。 3. 磁场定向有两种,间接磁场定向的角度是速度的积分,直接磁场定向的角度是磁链矢量的arctan2。 4. 按间接定向,定向角度是速度的积分,那么这里的速度我们可以叫它预测项,这个预测项比较特别,因为没有角度的同质项,所以这个估计器是临界稳定的,如果速度...

Explanation: An overtone is a higher frequency that accompanies the fundamental frequency. Overtones, also known as harmonics, are frequencies that occur in addition to the fundamental frequency of a vibrating item. When an item vibrates, the fundamental frequency, which is the lowest and loudest ...
