High-density controllable bubble structures are produced in the vicinity of radiating surface by artificially implant nuclei. Two kinds of typical cavitation structures produced by artificially implant nuclei are investigated. The focusing action and the physical origin of jet-induced cone-like bubble structure are analyzed. The sonochemical activity of cavitation structures is measured by using the standard method of potassium iodide dosimetry. The controllability of cavitation bubble cluster in the acoustic field is also discussed in this work.
通过人为植入核，在辐射表面附近产生高密度可控的气泡结构。研究了两种典型的通过人为植入核产生的空化结构。分析了聚束作用和射流诱导的锥形气泡结构的物理起源。采用碘化钾剂量法的标准方法测量了空化结构的声化学活性。本文还讨论了声场中空化气泡簇的可控性。
