在加工工业中，众所周知，颗粒形状是决定颗粒系统行为的重要因素。例如，具有技术意义的系统性质，包括流变性、悬浮稳定性、附聚、填充、渗透性等，受到颗粒形状的影响。在这方面，颗粒形状的表征和分析对于更详细地理解和改进颗粒工艺的发展至关重要。一般来说，很明显，这些系统的行为取决于粒子形状的统计特性。目前几乎没有技术可以预测所有不规则形状颗粒或一群不规则形状颗粒的力学和流体动力学行为。模型和相关性的缺乏可归因于颗粒形状的广泛多样性和复杂性、定义适合于建模的形状描述符的困难、测量形状的局限性以及缺乏表征颗粒形状的分类技术。在本文中，我们提出了如何使用锥形束X射线显微断层扫描（XMT）的三维颗粒形状可以测量，表征和分析的信息。(c)2005 Elsevier B.V.保留所有权利。
In the processing industries, it is well known that particle shape is an important factor that determines the behavior of particulate systems. For example, system properties of technological significance, including rheology, suspension stability, agglomeration, packing, permeability, etc., are affected by particle shape. In this regard, characterization and analysis of particle shape is essential for more detailed understanding and improved development of particulate processes. In general, it is clear that the behavior of these systems depends on the statistical characteristics of particle shape. Remarkably few techniques exist to predict the mechanical and hydrodynamic behavior of all irregularly shaped particle or a population of irregularly shaped particles for that matter. The lack of models and correlations can be attributed to the wide variety and complexity of particle shapes, the difficulty of defining shape descriptors suitable for modeling, the limitations of measuring shape, and the lack of classifying techniques to characterize particle shape. In this paper, we present information on how 3D particle shape can be measured, characterized, and analyzed using cone beam X-ray microtomography (XMT). (c) 2005 Elsevier B.V. All rights reserved.
