矢量

The performance of speed regulation of AC motor can compare with that of DC motor after the FOC is introduced into AC motor field.

采用矢量控制后交流电机的调速性能可以和直流电机媲美。

Using digital signal processor, TMS320F240, which is special for motor control, we develop a suit of speed adjustable, reliable and highly effective induction drive based on FOC principle.

文中对整个系统的硬件电路和驱动软件的实现都作了详细的介绍，同时采用了一种新型的PWM调制方法一电压空间矢量法来实现对异步电机的控制，提高了能量的利用效率。

Term for the formula true: the system is out of external force or the resultant vector of the external force received is zero.

这个式子成立的条件，是系统不受外力或受到的外力的矢量和为零。

Specifically, we have assessed the nerve root's response dependent upon segmental contact point, force, and applied vector.

具体来说，我们评估了神经根的反应力取决于段的接触点，并应用矢量。

The clue to an explanation of motion along a straight line was simple: external force is responsible for change in velocity; the force vector has the same direction as the change.

解释直线运动的线索是非常简单的：外力产生了速度的改变，外力的矢量其方向跟速度改变的方向相同。

Velocity is a measurement of speed and has nothing to do with mass; however, force is a vector that is applied to the particle to change the particle velocity, and when it is applied, mass is taken into consideration (acceleration = force / mass).

速度是速率的衡量标准，它和物体的质量无关；然而力是施加在粒子上并改变粒子速度的一个矢量，当它施加在粒子上时，质量就成为要考虑的因素

Especially it can find path between obstacles overlapped each other from the view of robot, which can't be realized by fuzzy plan, virtual force field or vector field histogram.

尤其是它能够发现前后重叠的障碍物之间的行走路径，这是模糊规划、虚拟势场、矢量场矩形法等方法无法实现的功能。

Force is a vector that gets applied to an object to change its velocity, and the object's mass is taken into consideration (Force = Mass * Acceleration).

力场是一个矢量。它作用在物体上可以使物体的运动速度发生变化。

Secondly, in terms of the mapping relationship between the tendon force space and the fingertip mnaipulating force space, the geometric method to establish the sets of manipulating force vector of fingertip at any configuration of the finger is proposed.

其次，根据钢缆张力空间与指端操作力空间之间的映射关系，给出了建立指端在给定操作位形处的操作力矢量集合的几何方法。

From the angel of four dimensions vector and physics observation, this paper discusses the coordinate transform relationship between the relative movement inertia reference frames.

文章从四维矢量、物理观测的角度出发，就相互运动惯性系之间的坐标变换关系进行讨论。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
