This method can be used to calculate the degradation of image quality as a result of any kind of image motion in the image plane, and easily used in the case of one dimensional motion.

该方法可以计算任何形式的图像运动导致的成像质量的下降，而且可以很方便地应用到一维运动的情况。

We know the equations so well from our last lecture from one-dimensional motion with constant acceleration.

上一课的方程我们，已经比较熟了，常数加速度的，一维运动方程。

I have a motion of an object along a straight line we'll call that one-dimensional motion.

假设有一物体，沿直线运动，我们把它称为一维运动。
