核孔膜测定液体粘滞系数的各种方法

Various methods for determination of liquid viscosity with nuclear track membranes

本工作对用核孔膜测定各种液体粘度(粘滞系数)的方法进行了较系统的研究。提出了绝对测量和相对测量方法,后者又包括绝对粘度和运动粘度的相对测量。研究说明,核孔膜是测定液体粘度的良好元件,体积小、操作方便,能给出准确的测定结果,便于在工业部门和实验室应用。

A systematic study has been performed of the methods for determination of liquid viscosity with nuclear track membranes. Absolute and relative measurements have been suggested, the latter including relative measurements of absolute viscosity and kinematic viscosity. The study shows that the nuclear track membrance is a unique element for determination of liquid viscosity because it is small in volume, accurate in results and easy to manipulate in industries and laboratories.
