摘要
通过三维非晶格无规行走，对线型和环型自由连接链（ＦＪ）及具有硬核势能的自由连接链（ＦＪ－ＨＣ）进行了模拟。采用Ｍｏｎｔｅ－Ｃａｒｌｏ法获得的大量和系统的运算结果表明，具有相同结构单元和相同分子量的线型和环型高分子链的均方回旋半径比ｇｓ与不同学派的理论值和实验值完全吻合。
This paper has simulated the Free-Jioned chains(FJ)and the Free-Joined chains with Hard Core Potential(FJ-HC) of ring-shaped and linear polymer coils by the random flight of tridimensional offlattice.The systematic calculated results using Monte-Carlo computer simulation technique show that the ratio of the mean-square radii of gyration g_s tended to 0. 5,which was identical with theoretical and experimental results of all scholars at the present time.
