摘　　要：对于毛细管粘度计,测量误差的来源主要有10种,其影响最大的是壁效应,它是流体在壁面处发生的化学吸附和物理吸附的总效应,它使得应用伯肖叶方程计算出的粘度值偏大,测量粘度时往往需要对粘度计进行修正。报道了应用流变模型测定不同条件下、不同流体的吸附力及其一些影响因素的研究成果。Being a total effect of the chemical adsorption and physical adsorption of the fluid, the wall surface has a great influence on capillary viscosity measurements. It leads to a positive deviation in the viscosity values calculated through using the Poiseuille Equation, and the corrections need to be made on the viscosimeter when measuring viscosities. The results of using a rheological model studied the assorption of several fluids at different conditions and various factors on these measurements were reported.
