摘要：
A phase modulation technique using a photoelastic modulator is employed for measuring the optical retardation as a function of temperature in the whole range of the nematic state. The surface parameters are determined self-consistently from both the capacitance and the phase retardation of the nematic liquid crystal. It is found that the surface anchoring energy is on the order of 1.0 erg/cm(2) at room temperature.
