摘　　要：介绍了波在胆甾醇型液晶中斜传播问题准确闭式解的微扰解法，其解对各向异性参数修正到二阶无穷小．在闭式中微扰项是已知的，该方法可用于研究波在胆甾醇型液晶中斜入射的传播现象．This paper presents a perturbational method with an exact closed form solution for the general propagation problem in a cholesteric liquid crystal, and this solution is correct to the second order infinitesimal for the anisotropy parameter. The perturbation terms are given in closed form and can be easily used to study propagation phenomena of oblique incidence wave in cholesterics liquid crystals.
