摘要
基于归纳演绎法对化工原理课程知识中的一些内部共性关联进行探究,分析了化工原理课程中应当把握的几条主线,主要包括质量守恒、能量守恒、推动力、传质通量和速率5个方面;还分别阐述了化工原理研究方法、化工原理课程知识各自的共性关联点。化工原理研究方法的共性关联点主要包括因次分析法、参数综合法、当量换算法和对比分析法等;化工原理课程知识的一些共性关联点主要包括传递过程模型的共性关联、传递速率分析的共性关联、传递计算数学模型中的共性关联、吸收和精馏操作中的相平衡间的共性关联、质量守恒定律间的共性关联、最小液气比和最小回流比的共性关联。通过对相关联的共性知识进行归纳演绎,学生可高效地掌握本课程的核心知识。
Based on the inductive deduction method,this article explores some of the internal commonalities in the knowledge of chemical engineering principles.It mainly introduces several main lines that should be grasped five aspects in the course of“principles of chemical engineering”,including quality conservation,conservation of energy,driving force,and mass flux,followed by the introduction of the common principles associated with the research methods of chemical engineering,including the secondary analysis method,parameter synthesis method,equivalent exchange algorithm and comparative analysis method.Then it introduces the internal commonalities of the knowledge of chemical engineering courses,including the common correlation of the transfer process model,the common correlation of the transfer rate analysis,the common correlation in the transfer calculation mathematical model,and the common correlation between phase equilibrium in the absorption and distillation operations,the common correlation between the law of conservation of mass,the common correlation between the minimum liquid-gas ratio and the minimum reflux ratio.By these lines,students can master the knowledge of the course.
