有相位差的

  • 两侧时间变化时,阀片启闭压差的变化之间存在一定的相位差可能引起泄漏甚至反向流动

    When the pressure difference changes with time, a phase shift will occur between the transient pressure difference and displace of valve flap, which could cause leakage and even reverse flow.

  • 如果信号的相位差别就会输出一个DC(直流)电压这个电压正比两个输入间相位差

    If the signals are out-of-phase the output will be a DC voltage that is proportional to the phase difference between the two inputs.
