摘要翻译：
本文讨论了用广义非线性sigma模型描述的三维链的动力学，给出了两个拓扑纠缠链的概率分布公式。文中还给出了一个有趣的例子，即一个链相对于$z-$轴只能形成离散的角。

英文摘要：
  In this work we discuss the dynamics of a three dimensional chain which is described by generalized nonlinear sigma model The formula of the probability distribution of two topologically entangled chain is provided. The interesting case of a chain which can form only discrete angles with respect to the $z-$axis is also presented.
