elastic boundary condition的意思|示意

Based on the elastic theory of liquid crystal and variation theory, the effect was studied, and the differential equation and boundary condition about the director of liquid crystal were obtained.

基于液晶弹性理论研究了这一效应，通过变分理论得到了液晶指向矢满足的微分方程及边界条件。

The non-classic boundary condition of the elastic instability has been educed by the energy functional variation analysis. So a criterion equation of the elastic instability can be got.

利用能量泛函变分的方法导出了发生弹性失稳的非经典边界条件，得到了失稳的判据方程。
