Uniform motion is only hypothetical. 匀速运动只是一种假设性的运动，实际上并不存在。
Uniform motion in a circle was at once changing and yet changeless, since it endlessly repeated itself. 始终如一的圆周运动既在变化又没有变化，因为它只是在不断地重复自己。
If a body is kept free of the action of forces,it will remain in its state of rest or of uniform motion in a straight line. 物体如果不受外力的作用，将保持静止的状态或沿直线作匀速运动。
If you were content to remain at rest or in uniform motion relative to an unaccelerated frame of reference, no force would be needed. 如果你愿意相对于一个非加速的参照系去保持静止或匀速运动，并不需要有力作用。
Newton's first law of motion: Every body continues in its state of uniform motion or rest unless acted by an external force. 牛顿第一运动定律:牛顿第一运动定律:一切物体总保持匀速直线运动或静止状态,直到有外力迫使它改变这种状态为止。
If a body is kept free of the action of forces, it will remain in its state of rest or of uniform motion in a straight line. 物体如果不受外力的作用，将保持静止的状态或沿直线作匀速运动。
This law states, "Every object in a state of uniform motion tends to remain in that state of motion unless a net external force is applied to it. 牛顿第一运动定律是这样描述的，“一切物体总保持匀速直线运动状态或静止状态，直到外力迫使它改变这种状态为止。”
Newton's first law of motion is also called Law of inertia. Inertia is the inherent property of body to continue in its state of uniform motion or rest. 牛顿第一运动定律又叫做惯性定律,它指出物体具有的惯性,即物体都具有保持匀速直线运动状态或静止状态的性质。
All the targets within a formation are generally considered as performing uniform motion with the same speed and heading, especially when they are in the state of cruising. 一般认为，在巡航状态下编队中的所有目标以同样的速度和航向匀速运动。
The experiment proves that this method can perfectly control the running modes such as starting,acceleration,uniform motion,slowdown and creeping of the hoist. 实验证明,该方法可更好地实现提升机的启动、加速、匀速、减速及爬行等各运行阶段的控制。
The hydrophone receives the water in the water the static pressure function, if static is motionless or makes the uniform motion, should not have the voltage output. 水听器在水中受到水的静压力作用，若静止不动或作匀速运动，应该没有电压输出。
This paper deals with a method of computation of electric feld in uniform motion of point electric change by using the effect in the space allording to the theory of relativity. 这篇文章用场所在空间的相对论效应给出了匀速运动点电荷的电场强度。
As Professor Wolfson points out, the essence of relativity can be summed up in a single sentence: The laws of physics are the same for all observers in uniform motion. 正如沃弗森教授所指出的，相对论的精髓可以浓缩成一句话：在所有相互作匀速直线运动的惯性系中，物理定律具有相同的形式。
The beat signal model of the stationary, uniform motion and accelerated motion target is sinusoid, Linear Frequency-Modulated (LFM) signal and polynomial-phase signal (PPS) respectively. 静止、匀速运动和加速运动三类目标分别对应着正弦信号、线性调频(LFM)信号和多项式相位信号(PPS)三种差频信号模型。
In this paper analyzes and demonstrates two problems in the experiment of using oscillograph:one is the function of triggering level,the other is why the horizontal scan spot moves in uniform motion. 本文对“示波器的使用”实验教学中关于触发电平的作用、调节它的目的和水平扫描点匀速运动的问题进行了分析和论证。
When Lorentz symmetry holds, spacetime is isotropic in the sense that all directions and all uniform motions are equivalent, so none are singled out as being special. 当劳仑兹对称成立时，时空是具有等向性的，也就是所有方向与所有等速运动皆等效，没有一个是特别的。
uniform motion in a straight line 匀速直线运动
He looks very manly in his uniform. 他穿着制服十分精神。
That morning they all had on their army uniform. 那天早上他们都穿上了军服。
It is this molecular motion that we call heat. 就是这种分子运动我们称之为热。
