  The mean field approximation is formulated within the framework of the
density field theory to study the properties of a Maier-Saupe nematogenic fluid
near a hard wall. The density and the order parameter profiles are obtained
using the analytical expressions derived in the linearized mean field
approximation. The temperature dependencies of the contact values of the
density and order parameter profiles are analyzed in detail. To estimate a
validity of the applied approximations, the obtained theoretical results are
compared with the original computer simulation data.
