摘要翻译:
用Monte Carlo模拟方法研究了二维三角形晶格上扩展物体的二元混合物的随机顺序吸附。沉积物体是通过在晶格上自避随机游动而形成的。我们在这里集中讨论形状的对称性对双组分混合物中沉积过程动力学的影响。在混合情况下,干扰极限的逼近是指数的,形式为:$\theta(t)\sim\theta_{jam}-\delta\theta\exp(-t/\sigma),$,参数$\sigma$的值由混合中不太对称的物体的对称顺序决定。根据制造混合体的物体的局部几何形状,混合体的干扰覆盖范围可以大于两个单分量干扰覆盖范围,也可以介于这两个值之间。文中还给出了不同分数浓度物体在混合物中的模拟结果。

英文摘要:
Random sequential adsorption of binary mixtures of extended objects on a two-dimensional triangular lattice is studied numerically by means of Monte Carlo simulations. The depositing objects are formed by self-avoiding random walks on the lattice. We concentrate here on the influence of the symmetry properties of the shapes on the kinetics of the deposition processes in two-component mixtures. Approach to the jamming limit in the case of mixtures is found to be exponential, of the form: $\theta(t) \sim \theta_{jam}-\Delta\theta \exp (-t/\sigma),$ and the values of the parameter $\sigma$ are determined by the order of symmetry of the less symmetric object in the mixture. Depending on the local geometry of the objects making the mixture, jamming coverage of a mixture can be either greater than both single-component jamming coverages or it can be in between these values. Results of the simulations for various fractional concentrations of the objects in the mixture are also presented.
