1. 'vector'是英国的词语,翻译为“向量”,通常在数学和物理学中使用。
2. 向量是指一个有大小和方向的物理量,可以用箭头表示。
3. 例句:
- The velocity vector of the object is pointing northeast.(物体的速度向量指向东北方向。)
- The force vector is in the opposite direction to the motion.(力向量与运动方向相反。)
- He used vectors to calculate the trajectory of the missile.(他用向量计算导弹的轨迹。)
- The acceleration vector is changing with time.(加速度向量随时间变化。)
- The electric field vector is perpendicular to the magnetic field vector.(电场向量垂直于磁场向量。)
- The vector product of two vectors is perpendicular to both.(两个向量的向量积垂直于两者。)
- The displacement vector is the shortest path between two points.(位移向量是两点之间最短的路径。)
- The gradient vector points in the direction of maximum increase.(梯度向量指向最大增加方向。)
- The momentum vector is conserved in a closed system.(动量向量在封闭系统中守恒。)
