A streak camera is used to measure the shape of sonoluminescence pulses from a cavitation bubble levitated stably in a sulfuric acid solution. The shape and response to an acoustic pressure field of the sonoluminescence pulse in 85% by weight sulfuric acid are qualitatively similar to those in water. However, the pulse width in sulfuric acid is wider than that in water by over one order of magnitude. The width of the sonoluminescence pulse is strongly dependent on the concentration of the sulfuric acid solution, while the skewed distribution of the shape remains unchanged.
使用条纹相机来测量在硫酸溶液中稳定悬浮的空化气泡发出的声致发光脉冲的形状。在重量百分比为85%的硫酸中，声致发光脉冲的形状及其对声压场的响应在定性上与在水中的情况相似。然而，硫酸中的脉冲宽度比水中的宽一个多数量级。声致发光脉冲的宽度强烈依赖于硫酸溶液的浓度，而形状的偏态分布保持不变。
