摘要
设计了既能验证光敏电阻的原理,又能演示光敏电阻应用的综合演示仪.在论述光敏电阻工作原理的基础上,提出了演示仪器的设计方法和仪器的结构框图,并给出了光敏电阻实际应用的电路原理图.该仪器在演示实验中应用,不仅可以提高学生对光敏电阻工作原理的理解,也能够提高学生对光敏电阻实际应用的了解,提高学生的动手能力与实践能力.
A kind of integrated instrument that could demonstrate the working principle and appli cation of photoresistor was designed. Based on the working principle of photoresistor, the design method and outline of the instrument were presented. The schematics of the application of photoresistor were also designed. The application of this instrument can not only improve the comprehension of the working principle and the application of photoresistor, but also strengthen students＇ hands-on skills and practical ability.
