要符合能量守恒原理，末总动能必须比初动能大这么多。
In order for energy to be conserved, the final total kinetic energy must be greater than the initial by this amount.
物体或物体系的总动能等于每种运动方式的动能之和，取决于质量和速度。
The total kinetic energy of a Body or system is equal to the sum of the kinetic energies resulting from each type of motion. The kinetic energy of an object depends on its mass and velocity.
多数这些好象是很统一，因此靠维里法则总动能应该是星系总引力聚合能的一半。
Many of these appear to be fairly uniform, so by the virial theorem the total kinetic energy should be half the total gravitational binding energy of the galaxies.
单个粒子的动量,会发生改变，但是总动量不变,而动能被损耗。
The momentum of the individual particles gets changed, but the net momentum did not change but the kinetic energy was destroyed.
总功指的是势能,和动能的总和。
但是却没有变化，总的振动能。
And you see that there's no change in the total vibrational energy.
对二连杆机器人手臂在水平状态下仅考虑总的动能，而忽略由于手臂挠曲变形而产生的位能变化。
For the two-bar robot arm, we focus merely the whole kinetic energy at horizontal condition, and neglect the change of potential energy due to the bending deflection of the robot arm.
控制振动板结构的体积速度是降低结构总声功率和振动能量的一种有效策略。
Controlling the volume velocity of vibration plate has previously been shown to be a good strategy to reduce its overall sound radiation and vibration energy.
叶栅中部和端部二次流均增强，总平均的二次流动能增大。对于该叶栅，叶片反弯曲亦不能提高叶栅流场的气动性能，直叶片叶栅总损失最小。
For the turbine stator cascade, the negative curving of blade can not improve the performance of the cascades as well, the total losses of straight cascade are the lowest.
不仅是在喂料口建立了喂料速率，使喂料口处于过冷状态还多消耗了总驱动能耗的20%，这是通过在一区恒定吸热实现的。
Not only is the feed rate established in the feed throat, but over-cooling the feed throat can extract as much as 20% of the total drive power by pulling heat constantly from zone 1.
