摘要：

On the basis of our recently suggested fan-shaped scattering model [J. Chem. Phys. 92, 5099 (1990)], a method to calculate the translational order parameter-tau for the uniaxially oriented liquid crystalline smectic phase is suggested. Using this method, tau is determined from the scattering profiles of the two-dimensional inner reflexes for two samples of the liquid crystalline side chain polymer in their smectic A phase. The relationship between tau and the orientational order parameter <P2> is discussed.
