line grating meaning in Chinese

线性数

And line grating is used to measure arc length in order to increase angle measuring precision , thus high differentiate locating in space can be realized
用长光栅测弧长来实现角度测量的高分辨率要求，实现空间上的高精度定位。
The paper introduces a method of design and realization that is based on the single chip computer 8051 , which adopts straight line grating sensor and realizes the three - coordinate high accuracy system of dynamic check and displacement measurement of nc machine
摘要介绍了一种以单片机8051为核心，采用直线光栅位移传感器，实现数控机床三坐标位移高精度动态检测系统的设计方法。
