Molecular dynamics (MD) simulation has been performed on the crystallization process of a single polyethylene chain from fully extended state in the vacuum at different temperatures (100500K with an interval of 100K). The results indicated that each of the simulated crystallization processes consists of three stages.

Molecular dynamics (MD) simulation has been performed on the crystallization process of a single polyethylene chain from fully extended state in the vacuum at different temperatures (100500K with an interval of 100K). The results indicated that each of the simulated crystallization processes consists of three stages. The first stage is a self\|cohesion stage, in which the extended chain collapsed to a coil with a sharp decrease of energy and size of the chain. The second stage is an ordering stage in which a lamella was formed by the chain in the way of the adjustment of the chain segments. The last stage is an adjusting stage, where the energy and the order keep almost constant, but the lamella shape varies to some extent. Even though there is a big gap in the time scale between MD simulation and laboratory experiments, the fratures of the simulated three stages were very similar to the three stages for bulk polymers in usual crystallization (the nucleation, the crystal gtrowth and the perfection stage). The collapse process of extended chain proceeded via a two\|step mechanism at 100K and 500K: a local collapse, forming compact domains, which subsequently coalesce to yield a fully collapsed state. It was found that the segments in the domains formed in local collapse step were ordered packed at 100K, while the randomly packed at 500K. The self\|cohesion rate of the chain is found intensively dependent on the crystallization temperature. The higher temperature resulted in the faster cohesion process. The crystallization temperature also influenced the thickness of the final lamellae. The thicker lamella structure is likely formed at lower temperature. This is different from the crystallization process of polyethylene bulk.\

用分子动力学方法(MD)研究了单链聚乙烯在不同温度(100K、200K、300K、400K、500K)下的结晶过程,并用能量和结构参数进行了描述.结果表明伸直分子链的结晶过程都经历了三个阶段,首先是伸直链的卷曲与聚集,然后通过链段的排列形成规整的片晶结构,最后是结晶形成的片晶在结构与能量上的涨落变化。研究表明,结晶温度越高,分子链的内聚速度越快.研究发现,分子链在内聚阶段经历一个局部凝聚的中间状态,在结晶温度很低(100K)时,局部凝聚的结构是有序的.而在500K时,该结构为无规线团.结晶温度的差异,一般来说,将导致得到的片晶厚度的不同.对于模拟的单链,随着结晶温度的降低而形成了较厚的片晶.该行为与聚乙烯本体结晶中片晶厚度对结晶温度的依赖性相反.在有序化阶段和之后的片晶调整运动阶段,分子链线团的回转半径基本保持不变.这与宏观多链体系的结果相同.另外,在模拟中发现,尺寸微小的单链聚乙烯晶片的扭转运动

A study using molecular dynamics has been done on a single chain crystallization from the extended chain under vacuum. The results show that this process consists of three stages. Since the cohesion energy and the entropy drive the extended chain crimpled with conformational state transitions on the backbone bonds. It is leading to a random coil, and ended “the cohesion stage”. In turn, “the ordering stage” starts, the chain segments of the coil are ordering and become a structure of lamella. It was found that the process under the second stage can be described by using Avrami equation (300 K, n=1 44,K =4 92×10 -4 s -1 44 ) which is extensively used in experiments. Therefore, the crystal growing mechanism belongs to the athermal nucleation and the chain defusion controled process. Finally, at “the adjusting stage”, the energy and the order of the system tend to be stable, and the shape of the lamella is fluctuating.

采用分子动力学(MD)模拟方法研究了真空状态下单链聚乙烯从伸直链开始的结晶过程。结果表明,整个模拟过程可以分成3个阶段。由于内聚能和熵的驱动,伸直链开始因各个σ键的内旋转和构象态跃迁而卷曲、聚集,渐渐形成具有一定密度的无规线团,这一阶段称为“内聚阶段”。从无规线团开始,通过分子链段的调整而形成结构比较规整的片晶(Lamela)结构,是“有序化阶段”。该阶段可用通常处理结晶实验数据的Avrami方程描述(在300K,n=144,K=492×10-4s-144),属于无热成核、受链段扩散控制的三维生长的结晶生长机制。在最后的“调整阶段”,模拟体系的能量和有序度基本稳定,但片晶的形状还在做动态调整。模拟过程的3个阶段与聚合物本体结晶过程中结晶成核、晶体生长和晶体完善不同但有相似之处。

Objective: The definition and meaning of generalized complexity were expounded,and the complexities of DNA sequences for four kinds of vertebrates were compared to verify the correctness and reasonableness of the definition about generalized complexity.Methods: Setting the invariant point,period 2,inequable probility period 4,chaotic and stochastic sequence as calculating examples,DNA sequence of mankind,hen,bull and mouse as examples,the repeatability complexity(GCR(2)) as main index,and the ordering information quantity(I) and surplus deree(R) as a reference index,all these values,GCR(2)、I、R,were calculated by their definition formulas.Conclusions: The results showed that in the bioevolution process all vertebrates were the same class of evolution,but the mankind was surperior to other three animals in the complexity(GCR(2)),ordering information quantity(I) and surplus degree(R) of DNA sequence.The evolution of DNA sequence of the vertebrates had a common feature that the emphasis point of entropy-decrement stage was the complexation of base correlation(GCR(2)),but not the ordering stage of base sequence(I).The above mentioned results fally accorded with the conclusion about the evolution of biomolecules in the bioinformatics.As a result the definition of generalized complexity was reasonable and correct.

目的:阐述广义复杂度定义和意义,比较四种脊椎动物DNA序列复杂性,检验我们提出的复杂度定义的正确性和合理性。方法:以不动点,周期2,不等概周期4,混沌和随机序列等简明序列为计算例,以“Bach/猴子击琴”历史著名质疑悬案问题为判据,检验广义复杂度定义的正确性。以人、公牛、老鼠和母鸡四种脊椎动为应用例,以重复性复杂度GCR(2)为主要测度指标,以有序化信息量I=log4-H1和剩余度R=1-H1/log4为参考指标,按定义公式计算GCR(2)、I和R值。结果:在简明计算例中,完全随机序列和完全规则序列的GCR(2)=0,GCC(2)=0,GCT(2)=0,说明完全规则不复杂,完全随机亦不复杂,这完全符合“Bach/猴子击琴”疑案问题的要求,检验了我们提出的广义复杂度定义的正确性。在四种脊椎动物DNA序列之间,GCR(2)、I和R值没有数量级差异,而在数量GCR(2)、I和R之间有数量级差异,即GCR(2)■I(bit),GCR(2)■R(%),而且人的GCR(2),I和R数值远远大于其它三种脊椎动物。结果表明,脊椎动物进化基本上在同一水平上,但人的DNA序列的复杂性、有序化信息量和后备存储剩余度均高于其它脊椎动...
