提出了一种测定向列液晶旋转粘度的简单方法。推导了向列液晶中瞬态位移电流的旋转粘度的理论表达式。表达式的有效性进行了数值检验。发现可以以足够的精度获得旋转粘度。通过本方法在不同温度下测量ZLI-2293（Merck Ltd.）的旋转粘度。
A simple method is presented for the determination of the rotational viscosity of nematic liquid crystals. Theoretical expressions for the rotational viscosity from transient displacement current in nematic liquid crystals are derived. The validity of the expressions is numerically examined. It is found that the rotational viscosity can be obtained with sufficient accuracy. The rotational viscosity of ZLI-2293 (Merck Ltd.) is measured at various temperatures by the present method.
