The theory and experiment verifies that it is a good pulsating attenuator and has large attenuation amplitude and wide attenuationband to pressure pulsation of oil source.
理论及试验证实它对油源压力脉动衰减幅度大,衰减频带宽,是一种性能良好的脉动衰减器。

The attenuation weak spot is the black strip in the lower left corner of the band.
天线的衰减弱点就是钢圈左下角的黑色覆盖物。
