在科学技术的许多领域内需要描述颗粒的大小和形状 ,例如 ,冶金学中的金属细颗粒 ,病理学中的细胞以及化学工程中的催化剂颗粒等都需要描述其大小和形状。各种形状因子可以简单地对颗粒进行描述 ,利用这些形状因子 ,我们可以从简单形状颗粒的性能来推测复杂形状颗粒的性能 ,并 In many fields of science and technology, the size and shape of the particles need to be described. For example, fine particles in metallurgy, cells in pathology, and catalyst particles in chemical engineering all need to describe their size and shape. A variety of form factors can be used to describe particles simply. Using these form factors, we can infer the properties of complex shape particles from the properties of simple shape particles, and
