讨论了谐振器在自由场和壁面中的吸收和散射。考虑了粘滞、热传导和辐射等因素的影响，得出了谐振腔体积存在一个最佳值，在该值处，谐振吸收最大。分析了在光圈中设置滤网对谐振器的减振效果，特别是阻尼量与滤网与光圈之间距离的关系。还考虑了非线性效应对吸收和共振频率的影响。
Absorption and scattering from resonators in a free field as well as in walls are discussed. Considering losses due to viscosity, heat conduction, and radiation, it is shown that there exists an optimum value for the resonator volume at which the resonance absorption is maximum. The effect of damping the resonator by means of a screen in the aperture and in particular the dependence of the damping on the distance between the screen and the aperture is analyzed. Nonlinear effects on the absorption and the resonance frequency are also included.
