非水液体中由修正的刹管法所产生的瞬态单一空化气泡的发光研究

在除水之外的7种非水液体和甘油的水溶液中，用修正的刹管法产生了有效直径达厘米量级的较大的瞬态单一空化气泡，这些气泡在崩溃时几乎都产生不同强度的光辐射。在其中的6种液体中，其光辐射强度与该液体的饱和蒸汽压和粘度是相关的。但在乙二醇和丙二醇中的气泡发光并不遵循这个规律，两者中的气泡发光都很强，但乙二醇中的发光强度的变化显示出某种非通常的规律性。本文还对瞬态单一气泡与通常的稳态单一气泡的发光特性进行了比较。

Luminescence of transient single cavitation bubbles in non-aqueous liquids produced by the modified tube-arrest method

Large transient single bubbles of effective diameters in cm’s were generated by the modified tube-arrest method in 7 nonaqueous liquids besides water and in glycerin-water mixtures. During collapse, nearly all these bubbles gave off light emissions of various intensities, which in 6 liquids were correlated with the saturation vapor pressure and viscosity of the respective liquid. Bubbles in ethylene glycol and propylene glycol did not follow this rule, but those in the former liquid showed some unusual regularity in luminescence variation and bubbles in both liquids were particularly bright. The luminous properties of the transient single bubble are compared with those of the usual stable single bubble.
