摘要

以传统落球法测量液体粘滞系数为背景，结合密立根油滴实验，将空气中的油滴模拟成液体中运动的小球，如此即可将落球法测量液体粘滞系数的思想应用到测量空气粘滞系数中．借助 CCD 成像系统捕捉油滴状态并使用智能手机记录其运动过程．并利用 tracker 软件对相关物理量进行采集，最终通过计算得出空气粘滞系数．

Abstract:

Based on the traditional falling ball method to measure the liquid viscosity coefficient，combined with Millikan oil drop experiment，the oil drop in the air is simulated as a small ball moving in the liquid，so that the idea of measuring the liquid viscosity coefficient by falling ball method can be applied to the measurement of air viscosity coefficient．The CCD imaging system is used to capture the state of oil droplets and use intelligent phones to record their movement process．The“ Tracker ”software is used to collect relevant physical quantities，and finally the air viscosity coefficient is calculated．

Key words: gas viscosity coefficient Millikan oil drop experiment drop ball method Tracker
