We studied random sequential adsorption (RSA) of parallel rectangles with random aspect ratio but fixed area using a newly developed algorithm that allows to generate strictly saturated packing of this kind. We determined saturated packing fraction for several different distributions of a random variable used for selecting side length ratio of deposited rectangles. It was also shown that the anisotropy of deposited rectangles changes during packing generation. Additionally, we examined the kinetics of packing growth, which near saturation obeys the power law with the exponent

1 / d \approx 1 / 3

, typical for the RSA of unoriented anisotropic shapes on a two-dimensional surface. Kinetics in the low coverage limit is determined using the concept of the available surface function. The microstructural properties of obtained random packings are evaluated in terms of two-point density correlation function.

具有随机纵横比的定向矩形的随机顺序吸附

我们使用新开发的算法研究了具有随机纵横比但固定面积的平行矩形的随机顺序吸附 (RSA)，该算法允许生成此类严格饱和的堆积。我们确定了用于选择沉积矩形的边长比的随机变量的几种不同分布的饱和填充率。还表明沉积矩形的各向异性在堆积生成过程中发生变化。此外，我们检查了填充增长的动力学，接近饱和时遵循幂律，指数为
