Abstract
We present a two-particle cluster variation theory to treat the inhomo geneous nematic system confined by two parallel planes which align the surface molecules perpendicular to them. Numerical calculations are m ade for a film composed of 20 molecular layers. The nematic-isotropic transition temperatures for typical values of the strength of the surf ace field are given and the layer dependences of the order parameter a re shown. The Monte Carlo simulation data are needed to demonstrate ou r results.
