zero vector

基本解釋

PWM wave is generated by splitting Zero vector quasi circular locus method.
該系統(tǒng)用零矢量分割的準(zhǔn)圓軌跡法生成PWM波形。
So, in terms of derivatives, it means d by dt of r cross v is the zero vector.
求一下導(dǎo)，那麼d/dt就等於零曏量。
According to the fact that the sum of a vector which forms a seal graph when its head and tail have been connected is a zero vector, the author works out the value of two summations.
本文借助於首尾相連成一個(gè)封閉圖形的曏量的和是零曏量，求得兩個(gè)和式的值。
