摘　　要：在现有的有关聚合物流变学的教科书或辅导书中,对非牛顿流体中"真实黏度"的概念解释不清,部分内容计算上有误。文中对毛细管中非牛顿型流体的真实黏度从概念、计算方法给予了详细的解释及更正。In some common textbooks or reference books concerning on polymer rheology, the concept of true viscosity of non-Newtonian fluid is explained unclear, and parts of the calculation results are wrong. In this paper, those questions were explained in detail. The authors made a distinction between the differential viscosity and the conventionally defined viscosity in capillary tubes, and some errors were corrected, and the analysis of example was given. Author expects this analysis is useful to further and more understand deeply the meaning of viscosity and to strengthen the teaching of this area and enable students to have further understanding of viscosity, improving the quality of teaching.
