To salve some problems such as large error and low accuracy in measurement of pressure, flow rate, velocity, the paper presents a computer aided test method (Hydraulic CAT) to improve the hydraulic experiment QCS003.

• 本文针对 QCS003 液压实验台在测量液压系统压力、流量、速度时存在的误差较大、灵敏度较低等缺点,提出构建该液压实验台计算机辅助测试(CAT)系统的改进方案。
