The Bohm criterion for a collisinal plasma sheath in an oblique magnetic field is investigated with a two-fluid model. It is shown that the upper and lower limits for the sheath criterion exist. And the range of the ion Mach number depends on the magnetic field and the incidence status of the ions.
