Good agreement is obtained between the theoretical prediction and the experimental data both for the acoustic resistance 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 acoustic resistance 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 acoustic resistance and acoustic mass will reduce slightly.
研究表明，随着气流马赫数的增加，吸声结构的消声系数明显下降，微穿孔板的非线性声阻和声质量修正值都略有减少。更需注意，在高速流条件下吸声结构的共振峰将会发生偏移。
