摘　　要：本文从科学的研究方法、流体动力学是血液动力学与血液流变学的基础、伯努利方程的物理意义与特点、牛顿粘性定律的物理意义与特点、泊肃叶定律对讨论血流问题的基础意义、体积流量的数学描述、速度梯度的概念与描述、雷诺数的物理意义与特点、关于流阻的讨论等九个问题提出自己在备课与教学中的思考与点评,也对当前某些教材中的不妥表述提出辨析。本文可为教师钻研教材与深入备课提供借鉴,也可供医学生深入学习和提高作参考。Based on the teaching practice, this paper discussed nine topics in fluid dynamics： scientific research methods, theo- retical foundation of hemodynamics and hemorheology, physical meaning of Bernoulli＇s equation, physical meaning of Newton viscosity law, Poiseuille principle on flow blood, mathematical description of volume flow, concept of velocity gradient, physical meaning of Reynolds number, and flow resistance. By combining preparing lessons and teaching practice, this paper comments on these nine topics and point out several inaccurate descriptions in some textbook. As a reference, it could benefit for teachers and students.
