Motion-work的意思|示意

The tension is not doing any work, because the tension, which is in this direction, is always perpendicular to the direction of motion.

压力不做功，因为这个方向的,压力，总是和,运动方向垂直。

At present work and energy in confined motion are treated with the method of work done by confined force which is analysed and calculated.

对于约束运动中的功和能，目前均采用具体分析和计算约束力所作功的方法来处理。

Later on, we'll go into more detail on how to work with symbols, Classic tweens, Motion tweens and Shape tweens, the Timeline and the Motion Editor.

后来，我们将进入更详细的关于如何工作与符号，经典的补间动画，补间动画和形状补间动画，时间轴和动画编辑器。

Further topics include kinematics, particle dynamics, motion relative to accelerated reference frames, work and energy, impulse and momentum, systems of particles and rigid body dynamics.

更进一步探讨运动学，质点动力学，于加速座标系上之运动行为，功，能量，冲量，动量和质点系统与刚体动力学。

It is impossible to have a cyclic machine that completely converts the random molecular energy of heat flow into the ordered motion of mechanical work.

不可能得到一种循环机器能把热流的无序的分子能量完全转变为机械功的有序运动。

But Frank married Lillian when he was 36, after he had done much of his time-and-motion work and years after he had set up his own engineering consulting business.

但是法兰克和莉莉恩结婚时已经36岁，在那以前他已经进行了大量的时间-动作研究工作，更于早年创办了自己的工程咨询业务。
