摘　　要：颗粒两相流测量技术指对连续相中的颗粒粒度和浓度等参数进行测量,是两相流测量中非常重要的分支。它与化工、能源、动力、材料、食品等诸多行业都有着密切联系,随着近年来工业的高速发展,颗粒两相流测量技术获得越来越多关注。结合近几年超声谱法在颗粒测量中的研究现状,重点回顾超声谱法颗粒两相流测量技术的应用进展状况,并分析其发展前景。The particle characterization technique is an extremely important branch in two-phase flow measurement, which can be used to explore quite a few physical properties, such as size and concentration of particle in a continuous medium. With the dramatic development of relevant industrial areas in recent years,there are more and more attentions on particle characterization technique that is closely related to the chemical engineering,energy, power, material preparation, pharmaceuticals, as well as food industry. In this paper, the developments and applications situation of particle characterization using ultrasound spectroscopy are mainly reviewed and summarized, and then the current challenge and developmental prospects are presented as well。
