摘　　要：光敏电阻存在延时特性,光敏电阻的响应时间随着光强的增大而减小,而且与光源有关。通过Origin软件比较几种光源的Δt-E图,得出手机光源曲线平滑,精确度较高,可以作为研究光敏电阻延时特性的一种有效光源。The experimental results show that the photosensitive resistance has the characteristic of time delay, the response time of the photosensitive resistance decreases with the increase of the intensity of the light, and it is related to the light sources.By origin software comparison of the several light sources At-E figure ,the curve of the light source of mobile phone is smooth and has high accuracy. It can be used as an effective light source for the study of the delay characteristics of the photosensitive resistance.
