各向异性材料的表面张力

The Surface Tension of Anisotropic Materials

本文提出一种能够统一处理各向异性表面张力的张量描述方法。通过引入表面张力张量,导出表面有关物理量和表面平衡条件,并根据材料对称性,分别对单轴液晶、双轴液晶和晶态固体的表面张力作了讨论,还给出了单轴液晶自由表面平衡的完整条件。

A method of describing the anisotropic surface tension is proposed. Some physical quantities and equilibrium conditions on surface are deduced. According to the symmetry of specific materials, the surface tension of uniaxial and biaxial liquid crystals as well as crystalline solid is discussed in this peper.
