对强激光脉冲引起的冲击波发射进行了实验研究。本文主要研究了甘油和蒸馏水在第一次气泡破裂过程中激波发射的条件。实验研究是在液体中作为温度和粘度的函数进行的。并与Poritsky （Proc 1st US Natl Congress apl Mech 813-821, 1952）和Brennen（空化和气泡动力学，牛津大学出版社1995）的理论工作进行了比较。据作者所知，这是对这些理论的第一次实验验证。
Shock wave emission induced by intense laser pulses is investigated experimentally. The present work focuses on the conditions of shock wave emission in glycerine and distilled water during the first bubble collapse. Experimental investigations are carried out in liquids as a function of temperature and viscosity. Comparison is made with the theoretical work of Poritsky (Proc 1st US Natl Congress Appl Mech 813-821, 1952) and Brennen (Cavitation and bubble dynamics, Oxford University Press 1995). To the best knowledge of the authors, this is the first experimental verification of those theories.
