电阻传感器物理原理验证及应用设计性实验研究

The designed experiment research in the validation and application of the resistance sensor's physical principle

以3种不同应用的电阻传感器为例,通过学生创新设计性实验的方式,验证传感器的物理原理和工程应用.本文详细介绍了在学生中开展设计性实验研究的实施模式,学生根据所学物理学原理和电子技术基础,在教师的指导下,从查阅资料开始,自主设计实验方案,完成验证电阻传感器中的物理原理、设计传感器在工程技术中的应用实验装置,使学生更好的掌握物理学中的理论知识,提高学生物理知识的应用能力、独立思考能力和科研创新能力.

As examples of three different applications of resistance sensors, based on the students＇ innovative designed experiments, we verify sensor＇s physical principle and engineering application. The developing implementation mode of designed experiment research in the student is introduced in detail. According to the principle of physics and electronic technology foundation under the guidance of the teacher, students start from the data access. plan designed experiments independently, complete the device that verifies the physical principle of resistance sensor and designs the sensor in the engineering application, to make students better to grasp the theoretical knowledge in physics, improve the students＇ application ability of physical knowledge, independent thinking and scientific re- search innovation ability.
