二维形状在一维直线上的随机顺序吸附动力学

Kinetics of random sequential adsorption of two-dimensional shapes on a one-dimensional line

摘要:

本文研究了由二维椭圆形、球形圆柱形、矩形和置于一维直线上的二聚体组成的饱和随机顺序吸附填料,以检验有关填料生长动力学的分析预测[A. Baule,Phys. Rev. Let. 119,028003(2017)]。结果表明,对于椭圆形和矩形填料,其动力学分别服从幂律,指数分别为$d=1.5$和$2.0$,与理论预测一致。然而,对于中等宽高比的spherocylinders和二聚体,观察到这两个值之间的过渡。我们认为,这种转变是一个有限的尺寸效应,由于接触函数的属性,spherocylinders。一般来说,即使对于非常大的填料,填料增长的动力学似乎也取决于填料尺寸。

英文摘要:

Saturated random sequential adsorption packings built of two-dimensional ellipses, spherocylinders, rectangles, and dimers placed on a one-dimensional line are studied to check analytical prediction concerning packing growth kinetics [A. Baule, Phys. Rev. Let. 119, 028003 (2017)]. The results show that the kinetics is governed by the power-law with the exponent $d=1.5$ and $2.0$ for packings built of ellipses and rectangles, respectively, which is consistent with analytical predictions. However, for spherocylinders and dimers of moderate width-to-height ratio, a transition between these two values is observed. We argue that this transition is a finite size effect that arises for spherocylinders due to the properties of the contact function. In general, it appears that the kinetics of packing growth can depend on packing size even for very large packings.
