Dataset accompanying the article: Analyzing X-Ray tomographies of granular packings

This dataset (and the added analysis software) belong to the article: Analyzing X-Ray tomographies of granular packings in Review of Scientific Instruments. The abstract of the article: Starting from three-dimensional volume data of a granular packing, as e.g. obtained by X-ray Computed Tomography, we discuss methods to first detect the individual particles in the sample and then analyze their properties. This analysis includes the pair correlation function, the volume and shape of the Voronoi cells and the number and type of contacts formed between individual particles. We mainly focus on packings of monodisperse spheres, but we will also comment on other monoschematic particles such as ellipsoids and tetrahedra. This paper is accompanied by a package of free software containing all programs (including source code) and an example three-dimensional dataset which allows the reader to reproduce and modify all examples given.本数据集（附带分析软件）关联发表于《科学仪器评论（Review of Scientific Instruments）》的论文《颗粒堆积体的X射线层析成像分析（Analyzing X-Ray tomographies of granular packings）》。该论文的摘要如下：本文以颗粒堆积体的三维体数据（例如通过X射线计算机断层扫描（X-ray Computed Tomography）获取的数据）为基础，探讨了先识别样品内单个颗粒，再分析其各项属性的方法。该分析涵盖对关联函数、沃罗诺伊胞（Voronoi cells）的体积与形状，以及单个颗粒间形成的接触点的数量与类型。本文主要聚焦单分散球体的堆积体，同时也会讨论椭球体、四面体等其他单形颗粒。本文附带一套免费软件包，内含所有程序（含源代码）与示例三维数据集，可供读者复现并修改文中所有示例。
