摘要
以球体旋转为例提出和说明了不用测量扭矩和转速两种数据的传统方法,而仅采用激光测取自由旋转体角速度一种数据,即可计算出流体内摩擦系数的新的简单方法。
The traditional method of calculating the friction coefficient of the liquid is to measure the moment of twist and the rotative velocity. With an example of rotative ball, this article presents a new simple method to calculate the above-mentioned coefficient that only the angle velocity of free rotative object should be measured.
