匀速运动

When a body is at rest, or in motion with constant velocity , the external force acting upon it are in equilibrium.

当物体处于静止或作匀速运动时，作用在其上的外力是平衡的。

In Newtonian mechanics, the motion of the charge in magnetic field is in equidistance helical line. It is composed of the uniform motion in magnetic field and the circular motion vertical to the magnetic field.

带电粒子在磁场中的运动，如果用经典力学分析，它做等距螺旋运动，是在垂直磁场平面内两个相互垂直方向的简谐振动和沿磁场方向匀速运动的合成。

These changes violate Newton's First Law, the Law of Inertia which implies that more energy is needed to change inertia (to overcome frictional forces and inertia) than to maintain inertia (to overcome only frictional forces).

这些变化违背了牛顿第一定律，也就是惯性定理――在不受外力或所受外力为零的状态下，物体总保持匀速运动或静止――也就是要改变物体的惯性需要额外的能量大于保持物体惯性的能量。

Algorithm for single images to the direction of uniform motion blur, is a simplified approach.

算法实现单方向匀速运动的图像去模糊，是一种简化处理方式。

A new detection scheme for stationary or uniform mution point targets from image sequence in the case of small SNR is proposed.

试图建立一种适合于检测图象序列中小SNR的相对静止或匀速运动点目标之快速三维检测算法。

Don't forget that these effects are absolutely symmetrical as between frames of reference in uniform relative motion.

不要忘记的是，在相对匀速运动系统中，这两种效应是完全对称的。

Well, while he is travelling along with uniform velocity, his granddaughter ages less-the usual time dilation.

嗯，当他正匀速运动的时候，他的孙女老得比较慢-普通的时间膨胀。

Numerical simulations were done for a bistable latch valve of the system by FLUENT, and three groups of datum for different fluids were obtained with the same effective exit sectional area. Besides, a static mathematic model for the electromagnetic valve was established based on the obtained datum. Secondly, the motion of the valve spool was realized by UDF file in FLUENT. Three kinds of motions, uniform, acceleration and motion driven by the coupling effect of the liquid resistance and the electromagnetic force, were calculated and compared. The dynamic characteristic of the electromagnetic valve was obtained by analyzing the relationship of the mass flow rate of the inside flow field of the electromagnetic valve, the change of the drop pressure of the passageway of the valve, and motion time.

并针对系统中的某双稳态电磁阀，使用商用CFD软件FLUENT对其进行内部流场的数值模拟，通过使用不同流体介质，不改变阀门有效出口截面积的情况下，分析得到的三组数据，建立了该电磁阀的静态数学模型；通过编写UDF文件，实现对阀芯运动方程的控制，在阀门做由闭合到开启、开启到闭合运动时，控制阀芯分别做匀速运动、匀加速运动以及阀芯受到液体阻力与电磁力作用力的耦合力的运动，分析了三种工况下电磁阀内部流场质量流率和阀门出口入口压降的变化以及运动时间，从而得到该电磁阀的动态特性。

Unlike her twin brother, she has not remained in a state of uniform motion.

不像她的双胞胎哥哥，她不是保持着匀速运动。

Plunder melds and run with this jewel!

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
