摘要 运用强1阶收敛的Milstein方法模拟了DNA分子伸长的随机波动,并与实验数据进行比较得到了较好的结果,从而为聚合物大分子的动力学模拟提供了另一种较好的方法。 The strong order-1 Milstein scheme is used to simulate the extension of DNA molecules in this paper. And the theoretical results match to the practical experiment data. Thus a preferable method ispresented to simulate the dynamics of polymer molecule.
