| 摘 要： | 使用无规行走模型,得到了线状分子链回转半径几率分布函数各阶矩的一般表达式。当链段数趋向无穷大时,无规行走链与Gauss链的渐近行为一致。本文还给出了无规行走链回转半径各阶矩的近似计算方法以及2阶矩、4阶矩、6阶矩与链段数关系的严格解析表达式。

| Abstract: | General expressions of the moments of the distribution function of the radius of gyration for linear chains were obtained by using the random walk model. It was proved that for the long chains, the asymptotic result is the same as that of Gaussian chains. An approximation method for calculating the moments of distribution function is given and explicit expressions for the first three moments are obtained. |
