所谓计量 ,就是为实现单位统一、量值准确可靠的活动。现代计量科学技术是以被测的物理量来分类的 ,即分为十大计量。这里只作一简单介绍 :1 长度计量 :是对物体几何量的测量技术。它包括 :线纹、端度、平面度、角度、粗糙度、渐开线样板等。2 温度计量 :温度是描写物体冷热
The so-called measurement, is to achieve unity of the unit, the value of accurate and reliable activities. Modern measurement science and technology is based on the measured physical quantity to be classified, that is divided into ten measurement. Here only for a brief introduction: 1 length measurement: is the measurement of the geometric quantity of objects. It includes: line pattern, end, flatness, angle, roughness, involute model. 2 temperature measurement: temperature is the description of objects hot and cold
