A liquid @F02366@ of thickness, or thicknesses, at which it is @S05900@ or @S05901@ with respect to small thickness changes. Unless the area of the @F02366@ is small, its composition may not be the same over its area and the (@M03872@) equilibrium thickness may be characteristic of the local condition only.
