摘　　要：研究流场中高分子溶液的行为具有非常重要的作用。运用格子链动态蒙特卡洛模拟研究泊肃叶流场中高分子溶液链的运动行为,考察了流场大小不同时对链的均方回转半径及取向度的影响。结果表明流场越大,链的变形越明显,且整条链沿着流场方向发生明显的取向。最后给出了高分子链在外加流场中的形态图,证实了流场中高分子链的变形及取向。It’s very important to study polymer solutions in flows. Monte Carlo simulations was used in this paper to study the activities of polymer chains in solutions under Poiseuille flow. Effects of flow with different strength on mean square radius of gyration and orientation were traced and results shown that chains became unfolded and oriented along the flow. At last the conformation figures were given to verify the observations.
