中文摘要:
      声空化是声学中特别是超声学中一个极其重要的物理现象。然而,尽管对于声空化的研究已经有着极长的历史,仍然有一些极基础的理论问题有待解决。如何来描述或表征声空化状态的强弱程度,就是这样一类的问题。本文对所谓的‘空化强度’概念提出质疑,并对影响声空化现象的一些因素作出分析,相应地指出解决问题的一些建议,以期人们对这个无论在理论研究和实际应用方面都有重要意义的问题深入研究。
英文摘要:
      Acoustic cavitation is an important physical phenomenon in acoustics especially in ultrasonics. However, even there is a long history about acoustic cavitation research, some essential theoretical problems are still needed to concern. It is this kind of problem that how to describe the degree of the strength of the cavitation. The so called ‘cavitation intensity’ or ‘cavitation strength’ was argued by the author, and some aspects of acoustic cavitation were analyzed as well. Suggestions are proposed to deal with this important theoretical and practical problem for further research.
