ke!1 xingzhuang颗粒形状(partiele shape)一个顺粒的轮脚边界或表面上各点的图象及表面的细微结构。通常包括投影形状、均整度(即长、宽、厚之间的比例关系)、棱边状态(如圆棱、钝角棱及锯齿状棱等)、断面状况、外形轮廓(如曲面、平面等)、形状分布等。常用的定量描述参数如下:形状系数指颗粒形状与某种规整形状(如球形)不一致的程度。包括体积形状系数八 V_一_一，，_一‘.5、一..一__~(人一卡)，表面形状系数人(人~若)与比表面积形 D产’~四产“一，、~门、ro DJ~~~.产、M、，、，~，，，人、。，，~。，、口，，、。一二‘士。、状系数尹(尹一乎)。D、V和S分别为颗粒的直径、体，F、刁、~r、r人’。一、”n一z礴月J尸甘””’户“J~阵、『下积与表面积。形状指数是表征颗粒外形自身特征的参数。主要有三轴径之比，称为均整度;长短径之比，称为长短度;短径与厚度之比，称为扁平度;长短度与扁平度之比，称为郑格(z ingg)指数。 此外，颗粒外接立方体体积与颗粒体积之比称为体积充满度。颗粒投影面积与最小外接矩形面积之比称为面积充满度。体积与颗粒相等的球的比表面积与颗粒比表面积之比称为真球形度。面积等于颗粒投影面积的圆的直径与颗粒投影图最小外接圆直径之比称为实用球形度。与颗粒投影面积相同的圆的周长与颗粒投影轮廓周长之比称为圆形度。粗糙度是指颗粒实际表面积和将表面看成光滑时的表面积之比。 颗粒的形状对粉料的流动性、充填性等粉料特性有较大影响。通常，用颗式破碎机，对辊破碎机及圆锥破碎机易得到多棱角颖粒，而用球磨机与筒磨机得到的顺粒更接近球形。用化学法或气相沉积法制备的超微颗粒也易接近球形。 (李楠)
