Applying wavelet denoise to improve the test signal, the dynamic characteristic parameters of a overflow valve were obtained by selecting characteristic point of the signal.
此系统应用小波降噪的方法提高测试信号的质量，然后提取信号特征点，得到溢流阀动态特性的各项参数。

Based on analysis of the principle of overflow valve dynamic characteristic test, virtual instrument system for the overflow valve measurement was designed.
在分析溢流阀动态特性测试原理的基础上，设计了溢流阀动态特性测试虚拟仪器系统。

Based on the analyses of main characteristic factors which affect the overflow spray-motion and their membership functions, the fuzzy relation matrix from the field data is established.
