8.2.- 度量衡

计量学是研究量的测量的科学。它的基础是力求在参考值与需要定量的对象或现象之间建立起关系,并获得测量的表达式。

测量必须是可重复的,而且不确定度尽可能小,误差取决于技术人员的专业知识或所用仪器的精度。在测量中获得的数值是为了以标准化的方式在单位系统中表示,例如国际系统。需要测量的领域很广,从社会科学、健康科学到最纯粹、最实验的科学都有。目前,在创新和优化测量仪器及其校准方面取得了进展。

我们都曾在某些时候做过一些测量,比如车辆轮胎的胎压,或者玩游戏所需的时间。有很多设备可以让我们测量基本量级。例如,可以用转子流量计或流量传感器测量流体的流量,用布顿压力计测量流体循环的压力,用热电偶测量流体的温度等。
