To analyze a single sonoluminescing bubble captured in the standing wave, a computational method, which consists of the Direct Simulation Monte Carlo method for the mixture of argon and water molecules inside the bubble and the Yasui's equation for the boundary condition, is proposed, considering the evaporation and condensation of water molecules across the bubble wall as well as the thermal diffusion. The calculation results show agreements of the characteristic histories on the bubble radius and temperature inside the bubble with the experimental one, and the species segregation of mixture gas inside the bubble, which may be associated with the pressure gradient in the interior of bubble during rapid bubble collapse.
