利用高速摄影技术，以每秒2000万帧的速度研究了激光诱导水中气泡的破裂过程。球形气泡在无界液体的情况下相比，吉尔摩模型。气泡在固体壁面前的坍缩表现出丰富的动力学特性，这取决于它们的归一化距离。前所未有的细节给出了事件的一般序列，导致多个冲击波和泡沫形状变形后崩溃。
The collapse of laser-induced bubbles in water is investigated by high speed photography at framing rates as high as 20 million frames per second. The case of a spherical bubble in an unbounded liquid is compared with the Gilmore model. Bubbles collapsing in front of a solid wall show a rich dynamics depending on their normalized distance. Unprecedented details are given of the generic sequence of events leading to multiple shock waves and bubble shape metamorphosis upon collapse.
