In this paper, starting from the definition of kinetic energy,and by establishing the inertial frame and the reference frame ,we have a discussion of the kinetic energy of rigid body and get some conclusions on kinetic energy of rigid body simply in rotation.

在建立惯性坐标系和运动坐标系的基础上，以动能的定义式为出发点，对刚体的动能进行剖析，并讨论了刚体纯滚动情况下的动能，得到了相关的结论。

And there is an approximate linear relationship between the momentum of the automatic mechanism and the length of the gas tube.

如β=〓与β=〓相比较（β角单位为弧度，其定义详见正文），前者与后者对应的气室最大压力之比可达65%，而对应的自动机动能之比可达60%；导气管内径对气室内气体压力冲量和自动机动能的影响存在极值点，且该极值点随导气孔的增大而有规律的增大；导气管长度对气室最大压力、压力冲量和自动机动能的影响呈单调递减规律，且自动机动量与管道长度之间近似符合一直线关系。

The kinetic energy of the collective motion have been parted three parts, which arevibrations in body-fixed frame, rotation of this system about the axes of Lab-frame and couplingbetween vibrations and rotation.

我们从多极形变系统小形变下的集体运动经典动能表达式出发，引入转动算符，把多极形变系统的集体运动动能从实验室系转到体坐标框架，从而将集体运动动能分解成体坐标框架下的形变振动、体坐标系围绕实验室系的转动及振动与转动的耦合。

Experiment shows that both the dry plate pressure drop and the wet plate pressure drop increase with the increase of the kinetic energy factor in plate hole but have no influence of the height of cap. The wet plate pressure drop linearly ascends as the clear liquid height increases. Liquid lift-up increases at first then decreases with the increasing of the kinetic energy factor in plate hole, increases with the clear liquid height increasing and the height of cap decreasing, but as the kinetic energy factor in plate hole increased, the influence of height of cap will gradually decreased.

实验表明干板压降、湿板压降均随板孔动能因子的增大而增大，不受罩体高度变化的影响，湿板压降随清液层高度的增大而增大，成正比关系；液体提升量随板孔动能因子的增大先增大后减小，随清液层高度的增大而增大，随罩体高度的增大而减小，但随板孔动能因子的增加，罩体高度的影响逐渐变小；漏液量随板孔动能因子的增大迅速减小，随清液层高度的增大而增大，但接近漏液点时清液层高度的影响不明显。

To verify the accuracy of CFD simulations, experiments were carried out. The results of simulations with user defined function of the effects of impeller type and stirring rate on the velocity field were in good agreement with the output of particle image velocity. The oxygen mass transfer model can be used to predict the process of oxygen mass transfer in a vessel, and the logarithmical expression can successfully describe the relation between the oxygen concentration and the dissolution time.

结果表明，(1)采用Fluent软件并结合用户自定义方程(user defined function， UDF)能够很好地模拟出实际搅拌器内流场分布，模拟结果与采用粒子成像技术(particle image velocity， PIV)的实验测量结果相符；(2)采用氧气传质模型能预测氧气在搅拌器内的动态传质过程，同时氧气浓度与溶解时间的对数关系式能较好描述试验搅拌器内氧气动态传质过程；(3)在相同搅拌速度下，圆盘涡轮式搅拌器产生的湍流动能分布范围要大于桨式搅拌器产生的湍流动能，而且湍流动能分布更均匀，湍流强度更大。

Based on the characteristics of space kinetic energy interception and advantages of proportional guidance, taking controlling the undershooting rate into account to increase precision, a terminal guidance method was designed to space kinetic energy interception problem.

针对空间动能拦截的特点，利用了比例导引法控制视线转率的优点，兼顾考虑了控制脱靶量以提高动能拦截精度，设计了空间动能拦截末段导引法。

In the case of attack by KE Projectiles the interceptors are exploded in front of them, to tilt them downwards so that they strike their targets yawed and therefore with much reduced penetration capability.

在动能弹攻击的情况下，拦截弹在动能弹前面爆炸，并使动能弹向下倾斜，因而动能弹攻击的是一个偏斜的目标，这就大大减小了侵彻威力。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
