摘　　要：本文用数码照相法研究落球法测量液体的粘滞系数实验,用截图软件对照片进行下落距离的测量.分析了数码相机作为时间测量仪器的使用,以及实验结果所能达到的测量精度.In this paper, we presented our research on experiment of falling ball method to measure the liquid viscosity coefficients with a digit camera. Measurement of the falling distance was based on the photographs captured by the screenshot software. We analyzed achievable measurement accuracy of the experiment results, when the digital camera was used as a time measurement instruments.
