摘要: 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.
