液体中气泡的混沌振荡降低了声化学系统的效率，在实际应用中应加以抑制。在本文中，基于双频方法的混沌控制方法进行了数值研究，并被证明是一种有效的方法，即使在案件与密集的能量输入。结果表明，双频方法在较宽的参数范围内（即使在高声压幅值下）都能有效地抑制混沌。此外，定量地讨论了两波功率分配对混沌控制的影响，清晰地描述了从稳定振荡到混沌的途径。
Chaotic oscillation of bubbles in liquids reduces the efficiency of the sonochemical system and should be suppressed in the practical applications. In the present paper, a chaos control method based on the dual-frequency approach is numerically investigated and is proved to be an effective method even for cases with intensive energy input. It was found that the chaos could be successfully suppressed by the application of dual-frequency approach in a wide range of parameter zone (even with high acoustic pressure amplitude). Furthermore, influences of power allocation between two waves on the chaos control are quantitatively discussed with clear descriptions of the routes from stable oscillations to chaos.
