| 摘 要： | 从超声电功率、超声作用时间和溶液温度来研究超声的空化效应,采用碘化钾溶液中碘的释放量来测定超声的空化产额,研究结果表明：在相同的电功率输入情况下,双频复合超声（25kHz/40kHz）释放碘的量远大于单频25kHz超声和单频40kHz超声释放的碘的量,双频复合超声的空化产额高于单频超声。

| Abstract: | Ultrasound cavitation effects have been studied by changing ultrasound power and ultrasound action time and solution temperature. And the iodine released from potassium iodide is used to determine the cavitation yield of 25kHz / 40kHz dual-frequency ultrasound, 40kHz ultrasound and 25kHz ultrasound. The results show： in the case of same ultrasound power input, the iodine content, i.e. the cavitation yield, of 25kHz/40kHz dual-frequency ultrasound is more than that of 40kHz ultrasound or 25kHz ultrasound. |
