本文首先对轴对称管流、二维管流和明渠连续流研究中无量纲参数的选择进行评述 ,通过对这些有分析解的流动的讨论 ,说明采用无量纲表达式的优点、无量纲方法的多样性 ,以及适当选择基本量的重要性。最后讨论了Bingham体阵性流研究中基本量的合理选择

In this paper, the comment s about the selection of dimensionless parameters in the investigation of axisymmeteric and 2-D pipe flow and cont inual open channel flow were given. The advantages of the dimensionless expressions, the diversity of the dimensionless method and the importance of the selection of the basic variables were demonst rated by the above flow which have analytical solution. The proper selection of the basic variables in the investigation of the intermittent flow of Bingham fluid was discussed at last.
