一、数据集合 Measurements of items e.g., Yearly sales volume for your 23 salespeople e.g., Cost and number produced, daily, for the past month 二、基本单元 The items being measured e.g., Salespeople, Days, Companies, Catalogs, . 三、变量 The type of measurement being done e.g., Sales volume, Cost, Productivity, Number of defects

频域仿真建模方法学 ▪ 频域仿真建模方法：面向S域的传递函数 G(s)，根据相似原理，得到与它相匹配的Z 域传递函数G(z)。 ▪ “匹配”：包括动态性能----G(s)的零点、 极点要与相应G(z)的零、极点匹配 ▪ 稳态性能----对于同一个输入函数，终值相 同

G( V, E ) where G ::= graph, V = V( G ) ::= finite nonempty set of vertices, and E = E( G ) ::= finite set of edges

基于过程模拟开发组件库SimuSage开发了通过氢气还原氩气气氛中的NbCl5制备超细铌粉的热力学模拟程序,讨论了蒸发温度、载气用量(Ar(g))、还原反应温度、H2(g)用量、收集区温度等关键参数的影响.研究表明:NbCl5(s)的蒸发率以及气相中NbCl5(g)的浓度取决于蒸发温度及氩气的用量;还原温度为1000℃时固相产物为Nb(s)单一相所需的最小H2(g)用量为20 mol/1 mol NbCl5;提高收集区温度有利于获得高纯度固相Nb粉产物
