We derive a supplemental evolution equation for a disclination line located on an interface between the uniaxial and isotropic phases of a nematic liquid crystal. This equation provides an additional kinetic relation accounting for the motion of an interfacial disclination line. In our treatment of the problem we neglect fluid motion. Our approach is based on the notion of configurational forces. To illustrate the role of our additional evolution equation, we consider two simple examples. We also identify an expression for the configurational force exerted by the uniaxial phase at the defect located on the phase interface.
我们推导了位于向列型液晶单轴相和各向同性相界面上的位错线的补充演化方程。该方程提供了一个额外的动力学关系，用于描述界面位错线的运动。在处理这个问题时，我们忽略了流体运动。我们的方法基于构型力的概念。为了说明我们的补充演化方程的作用，我们考虑两个简单的例子。我们还确定了单轴相在相界面上的缺陷处施加的构型力的表达式。
