摘要
采用视频图像精确测量小球在液体中下落的速度,通过斯托克斯公式得出液体的黏滞系数。与传统的光电门控制法和旋转法测量的黏滞系数值比较,视频图像法测量黏滞系数方法具有操作简单、综合性强等特点,可作为学生综合型、设计性实验,为传统仪器的改进提供了新思路。
The falling velocity of the ball in the liquid is measured accurately by the video image method and the viscosity coefficient of the liquid is obtained by Stokes formula.Compared with viscosity coefficient values measured by the traditional gate control method and the rotation method,the method for measuring the viscosity coefficient by the video image method has the characteristics of simple operation, high comprehensiveness,etc. A new method for the comprehensive and designing experimental teaching is provided,and the experimental principle can be used as a new idea for the improvement of traditional instruments.
