声场中相互作用气泡的本征频率
Eigenfrequencies of two mutually interacting gas bubbles in an acoustic field
摘要：
从理论上和数值上讨论了声场中两个相互作用气泡的本征频率。线性理论表明，与相邻气泡相互作用的气泡有三个本征频率随气泡间距的变化而变化，作用在气泡上的初级Bjerknes力的符号和大小也随本征频率的变化而变化.
英文摘要：
Eigenfrequencies of two mutually interacting gas bubbles in an acoustic field are discussed theoretically and numerically. It is shown by a linear theory that a bubble interacting with a neighboring bubble has three eigenfrequencies that change with the distance between two bubbles, and the sign and magnitude of the primary Bjerknes force acting on bubbles also change according to the change in the eigenfrequencies.
