摘要：

An order parameter is proposed for the uniaxial-biaxial transition in nematic-liquid crystals. The Landau-Ginzburg part of the free energy and the linearized equations of motion for the order parameter and hydrodynamic variables in the uniaxial phase are then derived. The equations are used to predict the power spectrum of light scattering above the uniaxial-biaxial transition.
