| 摘 要： | 研究悬浮在向列相液晶中带电胶粘引起的指向矢形变．假定胶粒是球形的，并且表 面电荷在球形颗粒上的分布是均匀的，球形颗粒使指向矢沿径向弱锚泊排列．我们得到了 指向矢形变的解析表示式，它是Ｋｕｋｓｅｎｏｋ等人所提出公式的推广、指向矢形变依赖于两 项衰减，它们分别正比于离开颗粒距离的ｒ２和ｒ３．

| Abstract: | The director deformation caused by a charged colloidal particle suspended in a nematic liquid crystal is studied. It is assumed that the colloidal particle is spherical and the distribution of surface charges on the spherical particle is homogeneous. The spherical particle imposes a radial alignment on the director with weak anchoring. We obtain an analytical expression for the director deformation and it is an extension of that proposed by Kuksenok et al. The director distortions decay, depending upon two terms which are proportional to r-2 and r-3 away from the particle respectively. |
