摘　　要：用半定量方法研究了光敏电阻的响应时间与照射光的照度和波长的关系,并给出了光敏电阻的上升时间和下降时间的测量方法.该实验可作为本科生的探索性实验,有助于培养学生的综合和研究能力.Using semi-quantitative method, the relationship between the response time of photoresistance and the intensity and wave length of the irradiation are studied. Meanwhile, a method measuring the rise time and the fall time of the photoresistance is introduced. This experiment is designed for the undergraduates and is helpful to develop the integrative and research abilities of the students.
