本文介绍了由附着在刚性壁上的不同尺寸气泡组成的系统的共振频率的理论和实验数据。研究了共振频率变化对气泡尺寸和气泡之间距离的影响。研究发现，气泡系统的对称模式共振频率随着r=R(02)/R(01)的增加而降低，其中R(01)和R(02)是系统中气泡的平衡半径。实验中检测到了对称和反对称振荡模式，在小气泡分离时对称模式的共振频率占主导地位，而当气泡距离较远时反对称模式的频率占主导地位。采用线性耦合振荡器理论模型来描述气泡系统的振荡，其中使用图像方法来近似壁面的影响。结果发现，耦合振荡器模型的预测与实验数据之间有相当程度的一致性。
This paper presents theory and experimental data on the resonance frequency of systems consisting of different-sized air bubbles attached to a rigid wall. Effects of the change in resonant frequency with bubble size and distance between the bubbles were studied. It was found that the symmetric mode resonance frequency of the bubble system decreased with increasing r=R(02)/R(01), where R(01) and R(02) are the equilibrium radii of bubbles in the system. Both the symmetric and antisymmetric modes of oscillation were detected in the experiments, with the resonant frequency of the symmetric mode dominant at small bubble separation and the frequency of the antisymmetric mode dominant when the bubbles were farther apart. A linear coupled-oscillator theoretical model was used to describe the oscillations of the bubble system, in which the method of images was used to approximate the effects of the wall. It was found that there was fair to good agreement between the predictions of the coupled-oscillator model with the experimental data.
