摘　　要：微型燃烧系统的特征长度很小,其流动、传热和燃烧具有的特性,与大尺寸的燃烧系统有许多不同.在进行微燃烧的实验研究中,实现对微燃料流量的精确测量是实验中的关键环节.文章介绍了目前国内对于液体、气体微流量的几种计量方法,并对各流量计的测量原理,测量装置性能进行了评述.供微机电及计量检测领域的工作者参考.The characteristic length of micro-combustion system is very small, and its flow, heat transfer and combustion have many differences from those of the large-size combustion system. For experimental research on micro-combustion,it is a key link to measure the micro-flow accurately. This paper introduces several domestic measure methods for micro - flow of liquid and gas, and reviews the measuring principles, measuring devices performance of the flow meters. The research can provide a reference for the workers of MEMS and metrology fields.
