【摘要】 数学模型是对实物原型简化、抽象而构造的数学结构。描述氧化铝生产种分过程的工艺模型有“一段法”的AP经验模型、“准理论模型”和“二段法”工艺模型三种。应用模型可以对生产工艺条件进行预测,为生产决策者提供决定实际工艺条件的参考意见。更多还原

【Abstract】 The constructions of practical objects or phenomena can be simplified or abstracted into Mathematic models through matheraatization. There are three kinds of process models for the description of seeded precipitation from sodium aluminate solution: one-stage A.P. empirical models, quasi-theoretical models and two-stage process models. Mathematic models can be used to predict process conditions and supply references to decision makers in the design of optimum process parameters.更多还原
