The theory of the elastic interaction of spherical colloidal particles immersed into a confined cholesteric liquid crystal is proposed. The case of weak anchoring on the particle surfaces is considered. We derive a general expression for the energy of the interaction between small spherical particles (with diameter much smaller than the cholesteric pitch) suspended in a cholesteric confined by two parallel planes. The resulting form of the interaction energy has a more complex spatial pattern and energy versus distance dependence than that in nematic colloids. The absence of translational symmetry related to helical periodicity and local nematic ordering in cholesteric liquid crystals manifest themselves in the complex nature of the interaction maps.
提出了关于浸没在受限胆甾相液晶中的球形胶体粒子弹性相互作用的理论。考虑了粒子表面弱锚定的情况。我们推导了悬浮在由两个平行平面限制的胆甾相中的小球形粒子（直径远小于胆甾相螺距）之间相互作用能的一般表达式。与向列相胶体相比，相互作用能的最终形式具有更复杂的空间模式和能量与距离的依赖关系。胆甾相液晶中与螺旋周期性和局域向列序相关的平移对称性的缺失在相互作用图的复杂性中表现出来。
