摘要
The dynamical motion of sonoluminescing bubbles formed from a mixture of water and hydrogen gas indicates that these bubbles contain hydrogen. Their spectrum is well matched by an ideal 6000 K blackbody radiating from a surface with a radius less than 1/4 mum . According to this model, the state of matter inside the collapsed bubble is so stressed that the photon mean free path is much smaller than 1 mum . Implications for various theories of the light-emitting mechanism and the role of chemical reactions are discussed.
