颗粒饲料粉化率测定仪教学模型的研制与应用

Development and Application of Teaching Model for Percentage of Powdered Pellets Tester

设计了操作简便、成本低廉的粉化率测定仪教学模型,用于本科实验教学环节。实践结果表明,学生通过亲手操作熟悉实验流程,加深了对测定颗粒饲料粉化率的意义和原理的理解,在很大程度上节约了实验成本。

Teaching model for percentage of powdered pellets tester,which have advantages of simple operation and low cost,are designed and used for undergraduate experiment teaching link.The result of teaching practice shows that the students can be familiar with the test process by operating the tester all by themselves,get a deeper understanding of the experiment significance and principle,and that the cost of the experiment is saved to a large extent.
