摘要
采用落球法研究了甘油的粘滞系数与温度的关系。通过测量小球在不同温度的甘油中下落的收尾速度,由斯托克斯公式计算出甘油的粘滞系数,利用计算机软件进行辅助处理,得出了甘油的粘滞系数与温度关系的经验公式。
This thesis aims to study the relation between viscosity coefficient and temperature by adopting falling - ball method. Falling - ball method is used to measure ending speed of a small ball when falling in glycerin in different temperatures, then glycerol＇s viscosity coefficient can be got according to Stokes＇s formula, and after being processed by computer assistant mathematical software, an empirical formula of the relation between glycerin＇s viscosity coefficient and temperature can be gotten.
