| 摘 要： | 本文以一种快捷的数值算法和程序模型来模拟计算各种尺度高分子自由结合链或等效自由结合链的均方末端距，以及末端距的各阶分布矩．并将计算结果与按统计力学式运算值进行了比较。该计算方法简便可靠，特别适用于长度较短的分子链或无规飞行轨道。不仅可弥补Ｇａｕｓｓ分布的偏差，而且为真实链的构象研究提出了新的途径．

| Abstract: | A simulation of distribution moments of end-to-end distance of a possibleconformation at a given moment of a freely jointed polymeric chain can be realized throughrepeated iterations of a matrices which is controlled by random numbers. A comparisonbetween the statistic data and the data obtaine from the calculations shows that the re-sults derived from the different methods taily with one another. Moreover,this will pro-vide a simple and effective way for describing structure and properties of a complex macro-molecular chain. |
