uniform motion state

The conclusion makes us both saving time in experiment and analyzing the uniform motion state of oil drops in detail to fit the theoretical need.

密立根油滴处于匀速运动状态时，才能测量时间。油滴在任意的运动状态下，经过多长时间、或者说在视野中运动多远的距离才?。

Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it.

每一个物体都保持它自身的静止的或者一直向前均匀地运动的状态，除非由外加的力迫使它改变它自身的状态为止。

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。
