摘要：

The complete time evolution of a Helfrich-type instability that is driven by twist energy in a cholesteric liquid crystal is presented. The modulation is investigated using an initially;uniform planar director configuration of a cholesteric liquid crystal (with helical axes uniformly aligned along the cell normal) whose pitch is substantially longer than the equilibrium value.
