列入机械工业部“六五”期间的本科研项目,经过和机械工业自动化研究所近两年研究,对几种表征气动元件流量特性的参数和试验方法进行了比较系统的对比分析、研究和试验,基本搞清了目前采用的几种表征参数、试验方法的特点和相互关系,明确了采用ISO/DIS 6358试验方法确定的音速流导C值和临界压力比b值,或有效面积A值和可压缩性效
Included in the Ministry of Machinery Industry, “Sixth Five-Year” period of this research project, after and Institute of Machinery Industry nearly two years of research, several characteristics of the flow characteristics of pneumatic components of the parameters and test methods were comparatively systematic analysis, research and Test, the basic characteristics of the current use of several characterization parameters, test methods and interrelationships, clear the use of ISO / DIS 6358 test method to determine the sonic velocity C and critical pressure ratio b value, or effective area A value And compressibility
