In the leakage characteristic test , the problem of small leakage flow automatic test is solved with the method of usage of an ellipse gear flow meter and a self - made interface circuit . in the dynamic state characteristic test , frequency sweeping and statistic methods are used and their results are compared with 1250 frequency response analyzer
在电液伺服阀动态测试实验中，采用了扫频法和统计法这两种不同的方法进行测试，并对实验结果与1250频响分析仪所测的结果作了对比，发现二者基本一致。
