丝状液晶分子指向的混沌运动

The Chaotic Motion of the Directors Exist it Nematics

本文研究了丝状液晶分子指向在周期外场中发生弗雷德里克兹转变的动力学方程。数值计算的结果表明，当周期场的有关参数在一定范围内改变时，分子指向运动经倍周期分岔序列进入混乱状态，此时液晶的有关物理性质将呈现出复杂的行为。

A reseach on dynamics of the Freedericksz transition in Nema-tical liquid crystals is made in thls paper.The computer calculation reveals that, going through a series of period-doubling bifurcation, the chaotic mo-tion of the directors exsit in Nematics.In this situation,the output of the optical beam will show complicated behavior。
