Good agreement is obtained between the theoretical prediction and the experimental data both for the acousticresistance and reactance.
理论预测的声阻和声抗与实验结果吻合良好。

The structure provides a lumped acoustic impedance having an acousticresistance proportional to frequency, and an acoustic inertance that is inversely proportional to frequency.
该结构提供了一个集总声阻抗具有声波电阻与频率成正比，和声学惰性是与频率成反比。

It is shown that the attenuation coefficient will decrease obviously with the increase of Mach number, and the nonlinear acousticresistance and acoustic mass will reduce slightly.
