电阻层析成象技术在两相/多相流检测中的应用

Application of electrical resistance tomography in measurement of two-phase/multi-phase flow

两相流（或多相流）是一种广泛存在的混合流动模式，电阻层析成象（ＥＲＴ）技术是一种可用于液固、气液两相流参数检测的高新测量技术．从其数理基础出发，介绍了ＥＲＴ系统构成，技术特点、国内外研究现状以及ＥＲＴ技术关键和发展前景等．

Two-phase flow (or multi-phase flow) is a wide exist mixing now model. Electrical resistancetopography is a new hi-technology measurement technique which is found wide application in theprocess production involving liquid/colid and liquid/gas two-phase flow. This paper presents its prin-ciple, the constitution of the system, the technical feature, the worldwide research situation, themain technique problem and the future of ERT.
