粒 degree testing is through 特定 仪 device and methods for powder degree features table/sheet 征 一项实验工 as. powder in day active and 工农业 production in application non 常广泛. powder, water 泥, plastics, 造纸, 橡胶, 陶瓷, product and other and other. in different application areas in, for powder features requirements is same, in has powder features indicators in, degree distribution is has application areas in most 受关注 一项 indicators. therefore true 实 反映 powder 体 粒 degree distribution is non important as. lower 面就我 specific lower about/regarding degree testing 方面 基 Knowledge and basic methods. 一, degree testing basic Knowledge 1, pellets: in dimensions scope/range inner tool has 特定形状 几何体. this 里 说 一 dimensions generally in mm to nano between, pellets not only solid pellets, also has 雾滴, and other liquid pellets. 2, powder 休: a large amount of different dimensions pellets formed pellets 群. 3, degree: pellets large small pellets degree. 4, degree distribution: use 特定 仪 device and methods 反映出 different pellets powder amount separation 数. has distribution and distribution types 形式. distribution also is micro separation distribution or frequency rate distribution, it table/sheet series 粒径区间 in pellets separation content. distribution 也叫积 separation distribution, it table/sheet small or large certain pellets separation content. 5, degree distribution table/sheet methods: ① table/sheet method: use table/sheet methods will 粒径区间 distribution, distribution 一一列出 methods. ② 图形 method: in 直角标系 in use 直方图 and and other table/sheet degree distribution methods. ③ 函数 method: use 数学函数 table/sheet degree distribution methods. this type of methods generally in research use. 如著名 Rosin-Rammler distribution is distribution. 6, and and other 效粒径: 粒径就 is pellets 直径. this concept is very simple 明确, that what is and other 效粒径呢, and and other 效粒径 has what 关系呢? 我们知道, has 圆球体才 has 直径, its it 形状 几何体 is has 直径, formed powder pellets also large more is 圆球形, is various 各样不规则形状, has sheet/slice 状, 针状, more and other and other. this complex pellets from upper is can use this concept table/sheet it large small. in 实际工 as in is 描述一 pellets large small most 直观, most simple amount, also can use this 样 一 amount pellets large small, therefore in degree testing in 我们引入 and other 效粒径 this concept.
