摘要
流量测量仪表的检定或校准是流量量值传递或溯源链中最重要的环节，通常可将其分为实流检定和干式检定（干检）两种方式。介绍了实流检定和干式检定的概念，并论述了各自的应用场合，强调了流量仪表在线实流检定的必要性及计量学特点。
The testing and calibration of the flow the rate measuring instrument is the important part for the flow magnitude. Usually they can be divided into real flow testing. This article introduces the concepts of real flow testing and dry testing, and discusses their respective application field, emphases the necessity and computational characteristic for the flow meter in the on-line real flow testing.
