Nano Ferrofluidic Scale the String Axle of Big Length to Radius

摘要

The scale structure and the experiment equipment are designed on the nano ferrofluidic scale the string axle of the big length to radius, according to the principle of the nano ferrofluidic scale. The experiment study is made on the problems of the scale performance relation associated with this string axle, the rotational speed and the excitation current big or small. The reliability of the nano ferrofluidic scale the string axle of the big length to radius is proved.
