超声空化效应和声化学研究进展

本文对声化学这门新学科进行了系统地论述。对声化学的引发机制──超声空化效应的动力学理论．包括目前已得到公认的Ｎｏｌｔｉｎｇｋ—Ｎａｐｐｒｉａｓ的“热点”理论，以及尚存争议的“空穴放电”理论作了介绍．在此基础上对声化学的反应机理进行了评述．并对声化学多相合成反应进行了论述．同时，指出了声化学机理研究中尚待解决的问题。

ADVANCE OF ULTRASONIC CAVITATION AND SONOCHEMISTRY

This paper gives a systemical review on the advance of ultrasonic cavitation and sonochemistry in neraly two decades. Hot-spot and Bubble Electrical Discharge theory of ultrasonic cavitation in nearly year development wre discribed. Herring Gilmore and Flynn's modification theory of ultrasonic cavitation were compared with NlotingNapprias' theory. Magulis' new bubble electrical discharge theory were introduod. The researching advances of the execticed mechanism of sonochemical reaction, hamogenerous and heterogenerous catalysis sonoreaction mechanism in nearly few years were summaried.
