摘要:
Starting with two Boltzmann‐like equations, a kinetic theory is made of the long‐wavelength disturbances that propagate in a two‐component neutral fluid. A transition is observed from separate adiabatic sound speeds for each gas in the case of weak coupling to the single adiabatic sound speed of the gas mixture plus strongly damped relative motion in the opposite extreme of strong coupling between the gases.
