    "abstract": "It is proposed that shock wave dynamics within the gas of a small bubble\nexplain sonoluminescence, the emission of visible radiation. As the bubble\nradius oscillates, shock waves develop from spherical sound waves created\ninside the gas bubble. As any such shock propagates toward the center, it\nstrengthens and, upon convergence and subsequent reflection, temperature of gas\ninside bubble increases dramatically in such a way that it can produce plasma.\nSince main radiation product in exploding epoch, nonadiabatic condition for\nimploding shock wave cool plasma and cause exploding shock wave can not\nsufficiently rise temperature to produce radiation. In this work we compare\ncooling time for plasma by bermsstrahlung radiation with collapsing time for\nthe imploding shock wave . We find a constraint on radius of bubble with\nrespect to temperature of water. This constraint condition explains\nexperimental results as to, why the cold water is fine for SL.",
