摘要(Abstract)：
从节流机构流量特性研究方法和研究现状出发 ,分析了目前节流机构流量特性研究存在的问题 ,并介绍了基于“液环法”的节流机构流量特性试验台。与传统试验方法相比 ,该试验台具有测试范围广、系统稳定性好、投资费用少、节能等优点。
The method and status on flow characteristic of the throttle mechanism are presented,moreover,the problems on reseaching the throttle mechanism at present are analyzed,and a new test bench based on liquid ring method(LRM) is introduced.Compared to the traditional method,LRM has great advantage on wide test range,better stability,less investments and energy-saving.
