本文用声化学效率的概念，报道了频率对声致羟自由基形成的影响，在氮气或空气环境中，高频（８００ｋＨｚ）超声辐照所致·ＯＨ的化学产率比低频（３８．４ｋＨｚ）超声辐照时高。
In this paper, we report the effect of frequency on the formation of hydroxyl radicals by using the concept of acoustic chemical efficiency. The chemical yield of · OH due to high frequency (800kHz) ultrasonic irradiation in nitrogen or air is lower than that of low frequency (38.4kHz High when irradiated by ultrasound.
