The law of variation in the signal with relative placement deviation of the two gratings is analysed and proved sufficiently. And a series of the equations about this law is given.

在此其础上，对“光栅付相对位置偏差——信号质量”变化规律进行了全面的分析验证，得出一系列表示这种变化规律的传递公式。

we asked. 'Measuring the relative speed and angles of the balls, the distances to the pocket and final placement of the white ball?'

我们问，“测算球的相对速度和角度，判断白球到球袋的距离以及最后的位置呢？

Method:40dry atlas specimens were used to measure anatomic data relative to screw placement technique with an electronic digital caliper and a goniometer.

方法：用电子游标卡尺和量角器对40例干燥寰椎标本测量与进钉技术相关的解剖学数据。

These mechanical devices that show the relative placement and movement of the planets and moons are sometimes called orreries.
