The steady state pressure balance and the diffusions in the boundary layer of a gas-blanketed plasma for the case that a magnetic pressure is much higher than a neutralgas pressure are calculated by the continuum approach under the assumption ofconstant but unequal temperatvares. With this assumption, simple forms describing the pressure balance, the diffusion fluxand the thickness of the boundary layer are obtained without separating the boundarylayer into diffusion and ionization regions. It is shown that a large pressure differencebetween a plasma and a neutral gas is induced when a neutral gas pressure is below thecritical pressure. Also it is shown that the diffusion of a neutral gas depends linearly onnumber density of neutral particles but does not depend explicitly on magnetic field.Pressure balance calculated by the present analysis agrees with measurements inAlcator and Ringboog.
