| 摘 要： | 研究了聚环氧乙烷链在三级旋转异构态模型中的微观构象及其三级相互作用对聚环氧乙烷链的持久矢量的影响．计算了聚环氧乙烷链在三级旋转异构态模型中的键段的先验几率．这种方法能计算重复单元极复杂的对称高分子链的先验几率，还能研究不对称高分子链的微观构象，同时导出了三级旋转异构态模型中的持久矢量计算公式．

| Abstract: | The average chain conformations of polyoxyethylene chain in the third\|order interaction approximation and the effect of third\|order interaction on persistence vectors are investigated. A priori probabilities of polyoxyethylene chains in the third\|order interaction approximation are also calculated,and this method may also be applied to study the average chain conformations of symmetric polymer chain with complex units and of asymmetric polymer chains. The expression of persistence vector in the third\|order interaction approximation is also produced. |
