通过最近开发的键波动方法模拟稠密的线性二维聚合物链。所考虑的链长和密度涵盖了从扩展的单链极限到致密聚合物熔体的跨越。这些链完全分离并遵循链延伸的幂律∼N 2 ν，N是链的键数。弛豫函数和均方位移显示出典型的劳斯行为，其区别在于各种弛豫过程的先因子不同
Dense linear two-dimensional polymer chains are simulated by the recently developed bond fluctuation method. The chain length and densities considered cover the crossover from the expanded single chain limit to a dense polymer melt. The chains completely segregate and follow a power law of the chain extension ∼N 2 ν, N being the number of bonds of the chains. Relaxation functions and mean square displacements display typical Rouse-like bahavior, with the distinction, that the prefactors for the various relaxation processes differ
