中文摘要：

在有从 2 ～ 30 μ m 的直径的微试管的 deionized 的流动特征被调查。试验性的结果证明在有 16 μ m 和更大的直径的微试管的流动特征与古典理论一致。不管多么，并且越小当直径被减少到 5 和 2 μ m，非线性的流动特征占优势，结果从常规理论的预言显示流动特征的重要离开直径，越 larger 离开。作为雷纳兹数字增加，非线性的流动特征减少的度逐渐地并且试验性的结果近似等于理论期望。在这研究的 minimumReynolds 数字仅仅是 2.46 x 10 ~(-5) 。

英文摘要：

The flow characteristics of deionized water in microtubes with diameters ranging from 2 to 30 μm are investigated. The experimental results show that the flow characteristics in microtubes with diameters of 16 μm and larger ones are in agreement with the classical theory. However, as the diameters are decreased to 5 and 2 μm, the nonlinear flow characteristics prevail and the results indicate significant departure of flow characteristics from the predictions of the conventional theory, and the smaller the diameters, the larger the departure. As the Reynolds number increases, the degree of nonlinear flow characteristics decrease gradually and the experimental results are approximately equal to the theoretical expectation. The minimum Reynolds number in this study is only 2.46×10^-5,
