采用电子顺磁共振自旋俘获法研究了在稀有气体存在下，47 kHz和400 kHz超声产生羟基自由基产率的频率依赖性。5,5-二甲基-1-吡咯啉- n -氧化物检测羟基自由基。在这里，我们证明了400 kHz超声产生的羟基自由基量与热导率的反比小于47 kHz超声产生的量。
The frequency dependence of the hydroxyl radical yield produced by 47 kHz and 400 kHz ultrasound in the presence of rare gases was studied by electron paramagnetic resonance-spin trapping. 5,5-Dimethyl-1-pyrroline-N-oxide was used to detect hydroxyl radicals. Here, we show that the amount of hydroxyl radical yield produced by 400 kHz ultrasound was less inversely proportional to the thermal conductivity than those induced by 47 kHz ultrasound.
