从等离子体光谱学的观点看单泡声致发光的困惑与未知
Mysteries and Unknows of Single Bubble Sonoluminescence from Viewpoint of Plasma Spectroscopy
摘要：
在含氢液体的多气泡和单气泡声致发光光谱中观察到的紫外连续光谱具有相同的物理性质-电子激发的氢分子的辐射解离（以及可能的重稀有气体如ArH的辐射解离）。在“水中气泡”的SBSL的情况下，振荡气泡实际上由具有周期性变化的水蒸气量的氢/氩混合物组成。所提出的机制是能够解释所有可用的光谱观测没有任何外来的假设，但在条款通常的等离子体光谱。
英文摘要：
UV continua observed in multi-bubble and single-bubble sonoluminescence spectra of hydrogen-containing liquids have the same physical nature - radiative dissociation of electronically excited hydrogen molecules (and possibly hydrides of heavy rare gases like ArH). In the case of SBSL of "air bubble in water" the oscillating bubble actually consists of a hydrogen/argon mixture with periodically changing amount of water vapor. The proposed mechanism is able to explain all available spectroscopic observations without any exotic hypothesis but in terms usual for plasma spectroscopy.
