| 摘 要： | 在改进的U型管装置中观察到一种圆锥气泡声致发光现象。声致发光产生的单个光脉冲的能量可达到约1.4 毫焦. 脉冲宽度约100 毫秒。发光光谱由连续光谱上叠加C2,CN,和CH的激发态光谱构成。这种圆锥气泡声致发光为单泡声致发光和多泡声致发光提供了一种联系。

| Abstract: | The conical bubble sonoluminescence (CBSL) from the collapse of the bubble was observed in an improved U-tube apparatus. The emitted light energy of a single CBSL flash was measured to be $\sim $ 1.4mJ. The pulse width was about 100$\mu$s. The spectra of luminescence were continuum superimposed with the spectral bands from the excited-state C2, CN and CH. The CBSL provides a link between the light emission of the single-bubble and the multi-bubble sonoluminescence (SBSL and MBSL). |
