【摘要】 化工计算是化学工程学的基础,在化工计算中衡算体系的划定是一项重要环节。以物料衡算为例,说明了化工计算衡算体系划分的多样化和重要性,指出了选择衡算体系的基本原则和一些具体的方法和技巧。恰当选择化工衡算体系不仅可以简化计算、提高衡算效率,而且可以避免错误的出现。更多还原

【Abstract】 Chemical calculations are the basis of chemical engineering. In chemical engineering calculation,division of balance calculating system is an important part. Took the material balance as an example,the diversification and the importance of balance chemical calculation division were explained,the basic principles to choose the balance calculating and some specific methods and skills were pointed out. Proper selection of the balance calculating system can not only simplify the calculation and improve the efficiency,but also avoid the errors.更多还原
