The total and of the pitot tube were measured when the opening of the regulating valve was changed with keeping the flowrate fixed as well as unchanged the opening of the regulating valve with invariable flowrate. Then, the dynamic pressure signals were analysed with the method of PSD after computed and normalized and a better result of frequency-domain distribution was obtained. In addition, the average energy was defined and used for the analyzing of disturbance signals of regulation valve.

首先利用皮托管对相同流量不同开度及相同开度不同流量下的总压及静压信号进行测量，然后经过计算得到动压信号并进行归一化处理；其次，对归一化处理后的动压信号进行功率谱分析，取得了较好的频域分布结果；同时定义了信号的平均能量，并将其应用到了调节阀扰动信号的分析中。
