用统计物理的方法讨论了胆甾相液晶在垂直螺旋轴方向的电场作用下螺旋结构的变化，得到了螺距ｈ和阈值电场强度Ｅｃ的近似表达式。结果表明：ｈ和Ｅｃ与场强、液晶的本征螺距、液晶分子结构及温度等有关
The change of the helical structure of the cholesteric liquid crystal under the action of the electric field in the direction of the vertical helical axis was discussed by means of statistical physics. The approximate expressions of the helical pitch h and the threshold electric field Ec were obtained. The results show that h and Ec are related to the field strength, the intrinsic pitch of liquid crystal, the molecular structure of liquid crystal and temperature
