| 摘 要： | 对聚合物晶体中各种高分子链的构象进行了研究,找出了它们的三维对称性,并用直线群来表征。在此基础上,讨论了分子链在空间群中排布的规律性,即在空间群中高分子链的对称性与所在位置的对称性相呼应。并利用直线群讨论了有序-无序高分子链所在空间群转变的规律性。

| Abstract: | The three-dimensional symmetry of a macromolecular chain was characterized by the line group. Regularities of packing of macromolecular chains in a space group were shown. That is in a space group the symmetries of a macromolecular chain have to correspond with the symmetries of the position occupied by the chain. Order-disorder transitions in polymer crystals were studied by means of line groups. |
