A New Monte Carlo Algorithm of Polymer Undergoing Ultrasonic Degradation
-
摘要: 设计了一种新的Monte Carlo算法,在计算机上模拟了高分子链的超声裂解过程。首先根据Ovenall模型用遍历法对高分子链进行模拟断裂,随后进行倒接,进而反演了整个裂解过程。在获得大量模拟结果的基础上,分别研究了极限断裂次数的频率分布,最可几极限断裂次数与聚合度之间的关系,极限断片长度的平均分布,以及分子量多分散系数与裂解程度之间的关系。Abstract: A new Monte Carlo algorithm is adopted to simulate the process of polymer undergoing ultrasonic degradation on computer. First , a single polymer chain is simulated cracking thoroughly by ovenall model, then fragments are connected conversely and in this
