在粉末技术中，粒度表征问题的范围从确定几厘米大小的岩石碎片的形状到表征柴油机烟灰和工业上重要的颜料等物品的形状和结构的问题。在本章的第一节中，我们将介绍用于表征岩石碎片形状和大小的技术，这些岩石碎片足够大，可以直接在感兴趣的项目上进行测量。在后面的章节中，我们将讨论如何使用计算机辅助图像分析来观察非常小的细颗粒的二维图像。随着计算机辅助图像分析的复杂性的增加和处理成本的福尔斯下降，许多目前仅限于二维表征的技术将扩展到三维。在第三部分中，我们将研究动态行为如何被用来表征翻滚的细颗粒的形状。
In powder technology the size characterization problems range from determining the shape of rock fragments measuring several centimeters to the problems of characterizing the shape and structure of items such as diesel soot and industrially important pigments. In the first section of this chapter we look at the techniques for characterizing the shape and size of rock fragments that are large enough for measurements to be made directly on the items of interest. In a later section we discuss how computer-aided image analysis is being used to look at two-dimensional images of very small fineparticles. As the sophistication of computer-aided image analysis increases and the cost of processing falls many of the techniques currently limited to two-dimensional characterization will be extended to three dimensions. In the third section we look at how dynamic behavior is being used to characterize the shape of tumbling fineparticles.
