角频率
Angular frequency

  角频率(angular frequency) 角频率是按正弦型规律而改变的现象的波动率的一种量度。设有一个点以等速率v沿着半径为,-的圆周进行运动,它走完一周需要时间T一2二:/v,因而运动的频率为f一1/7’。于是角频率。定义为每单位时间所经过的弧度数。因为每周有2二弧度,故。一2侧T二2对。 图中动点的位置可以用分量的形式表示,二-厂c(),氏v一rsin夕。设任意选取在初瞬t一。时动点的位置,即图中的点P,则夕一。t,动点的位置由二~”C()“‘t,夕一rsin州给出。最后这两个方程指示位个y运动方lbl角频率的图示说明置分量的正弦型的或简谐的性质,也说明了角频率的主要用途。谐运动以及可以用谐运动描述的现象,随时间的变化可以表示为三角函数,其辐角为乘积的t。参阅“频率(波动)”[frequeney(wavemotlon)马、“谐运动”(harmonie motion)条。 [克里沃(K.L.Kliewer)撰二
