通过高分子链的模型的计算来研究高分子链构象的尺寸与能量的分布．结果表明，高分子的链构象在小尺寸范围布居数增多；高分子的链构象在小尺寸范围存在比较稳定的链构象状态；在小尺寸范围比较稳定的链构象多具有类似棒状等非球形结构；高分子的链构象的尺寸与能量的分布显示熵弹性具有不对称性． Through the calculation of the polymer chain model to study the distribution of the size and energy conformation of the polymer chain. The results show that the number of chain conformations increases in a small size range. The chain conformation of polymers has a relatively stable chain conformation in the small size range. The more stable chain conformations in the small size range have a non-spherical shape Structure; the distribution of the size and energy of the polymer chain conformations shows that the entropy elasticity has the asymmetry.
