中文摘要：

在激光和超声的联合照耀下面， cavitary 水泡在金 nanoparticle 的表面上被产生。导致激光的热效果，超声的成穴 el- fect 和激光和超声的 synergistic 效果为成穴水泡的颤动借助于动态过程的调查被学习，与不同外部反对 -- ditions 象激光力量那样，超声紧张，等等。成穴水泡的动态过程能被激光或超声的照耀修改，这被发现。激光力量的改进能增加成穴水泡的批评半径，当超声的可以加强颤动时。成穴水泡可以由于激光和超声的 synergistic 效果变得更稳定。在激光和超声之间联合的变化能影响 synergistic 效果，这也被发现。

英文摘要：

Under combined irradiation of laser and ultrasound, cavitary bubbles are generated on the surface of gold nanoparticle. The laser-induced thermal effect, ultrasonic cavitation el- fect and the synergistic effect of laser and ultrasound are studied by means of the investigation of the dynamical process for the vibration of the cavitation bubble, with different external con- ditions such as laser power, ultrasound intensity, etc. It is found that dynamical process of the cavitation bubble can be modified by the irradiation of laser or ultrasound. The enhancement of laser power can increase the critical radius of the cavitation bubble, while that of ultrasound may intensify the vibration. Cavitation bubble may become more stable due to the synergistic effect of laser and ultrasound. It is also found that variation of the coupling between laser and ultrasound can affect synergistic effect.
