通过实验和分析研究了声场和多气泡声致发光场之间的关系，以阐明声化学反应场。研究了在改变驱动频率、施加到换能器的电压和池底部厚度等实验条件的同时，在填充有蒸馏水或鲁米诺溶液的矩形玻璃池中每个场的变化。对于声致发光场，测量声致发光（SL）的强度并观察其分布。对于声场，从理论上分析了声能密度，并从光学上观察了声压分布。比较它们，可以清楚地看出，SL 发生在细胞内驻波场的压力波腹处。发生 SL 的声压有上限和下限。这解释了驻波场中 SL 的幅度依赖性和空间不均匀性。
The relationship between a sound field and a multibubble sonoluminescing field has been studied experimentally and analytically to clarify the sonochemical reaction field. The variation of each field in a rectangular glass cell filled with distilled water or a luminol solution was investigated while changing experimental conditions such as driving frequency, applied voltage to the transducer, and thickness of the cell bottom. As for the sonoluminescing field, the intensity of sonoluminescence (SL) was measured and its distribution was observed. As for the sound field, sound energy density was analyzed theoretically and sound pressure distribution was observed optically. Comparing them, it became clear that SL occurred at pressure antinodes of a standing-wave field in the cell. There are upper and lower thresholds of the sound pressure for SL to occur. This explains the amplitude dependence and spatial nonuniformity of SL in a standing-wave field.
