摘要
通过对落球法液体粘滞系数测定仪的改进,消除了传统仪器的诸多弊端,保证了金属小球沿容器中心准确下落,计时准确性也明显提高,从而使测量误差大大降低。
Through modifying by using liguid viscosity coefficient recegnizer falling - sphere method , we have eliminated many malpractices of traditional instrument , and guaranteed the priU fails along the vessel center accurately. Thus the accuracy of timing obviously increeases the measuring error reduces greatly.
