摘　　要：实践证明,实验教学效果的好坏主要是由实验内容决定的。学生普遍对日常生活中比较熟悉的具体应用感兴趣,将具体的应用实例引入到教学实践能吸引学生的注意力,激发出学生学习的兴趣和热情,收到意想不到的实验教学效果。通过介绍电阻应变式低量程厨房秤专用称重传感器的内部电路结构、主要技术参数、实用电路设计等,阐述了怎样将电阻应变式称重传感器应用于实验教学的思想方法和实践操作过程。提炼的实验教学思想和方法,对实验教学改革具有一定的参考价值。According to educational practice,the learning effect of laboratory course is determined by the experiment contents. Students are normally interested in the particular applications which they are familiar with in daily life. By introducing the particular applications into the lab courses,the learner’ s attention is attracted on the lab works,and their interest and enthusiasm could be stimulated,which result in good learning effect. This paper demonstrates how to introduce the particular applications into the lab courses,and the detailed practice approaches are presented with an example of a resistance- strain gauge based weight sensor for application in kitchen. The internal circuit structure of the weight sensor,the main technique parameters,and the application circuit design are presented in the course. The thoughts and methods of laboratory teaching distilled in this paper may be a helpful reference for the reform of laboratory teaching.
