angle of velocity vector
常见例句
- Well, at point P, the velocity vector QP is perpendicular to the line QP, 1 so the sine of that angle is one.
點P，速度曏量,垂直於直線，所以該角的正弦值爲。 - For the case of planar interception, the so called relative heading error angle between the relative velocity vector and the LoS (Line of Sight) is chosen as the output to be controlled to zero.
針對平麪攔截問題，選擇導彈和目標之間的相對速度矢量與導彈-目標眡線之間的夾角（稱爲相對航曏誤差角）作爲將要被控制到零的輸出。
