声空化物理研究和核发射实验的近期进展

Recent developments in the study of acoustic cavitation and related experiment on nuclear emission

  • 摘要: 简要概述了20世纪20年代起多泡声空化的发现、研究和应用.随后重点介绍了20世纪90年代初实现的稳态单一气泡;由于它的实现,对声空化的实验研究和理论研究迅速取得进展,特别是在对气泡内部的极端条件(高温、高压、高密度)以及对气泡内声致发光的机理研究方面.同时还介绍了我国早在20世纪60年代实现的瞬态单一泡以及近期的一些实验结果.文章最后提到2002年3月美国报道的声空化核辐射实验,这个实验正在激发人们对声空化的更多关注.

     

    Abstract: The discovery, study and application of multiple-bubble acoustic cavitation since the 20′s of the last century are first briefly reviewed. Attention then is drawn to the realization of a stable single bubble in the early 1990′s, after which experimental and theoretical studies of acoustic cavitation progressed rapidly, including studies of the extreme conditions(high temperature, high pressure and high density) inside a cavitation bubble and the mechanism of its sonoluminescence. The much earlier observation of a transient single bubble in China in the 1960′s is next described together with some recent results. Finally, a most recent(March 2002) experiment by Taleyarkhan R P et al. on nuclear emission by acoustic cavitation which has stirred wide attention is recounted.
