Based on potential flow and perturbation theory, a theoretical model is derived to describe the pulsation, translation, and deformation of twin bubbles in an ultrasound field. The amplitudes of radial oscillation, translation, and deformation of twin bubbles are found to depend on initial translation velocities. The radii, translation, and deformation of twin bubbles also exhibit periodic behavior. As the initial translation velocities increase, the periods of two bubbles' oscillations reduce, and the instable area in the phase space of R-R enlarges because of the interaction between bubbles.
基于势流和微扰理论，推导了一个理论模型来描述双气泡在超声场中的脉动、平移和变形。发现双气泡的径向振荡、平移和变形幅度取决于初始平移速度。双气泡的半径、平移和变形也表现出周期性行为。随着初始平移速度的增加，两个气泡的振荡周期减小，由于气泡之间的相互作用，R-R 相空间中的不稳定区域增大。
