| 摘 要： | 利用边界层能量积分关系式的近似处理方法，对幂律流体贺管层流进口段长度及其进口段效应压力损失与流量修正系数进行了分析与近似计算，并且讨论了幕律流体的流动指数n与进口处修正雷诺数Re对进口段长度和压力损失系数的影响，特别是当n＝1时，本文的解与文献[2]中的解完全一致，因而间接验证了本文结果的可靠性。

| Abstract: | Using approximate dealing method to the momentun integral eguation, the development of the boundary layer in the enhance region and coefficients of the entrance region effect are analyzed and calculated. Furthermore, the effects of flow-index of power-law fluid and the entrance modal Reynolds number on the entrance region lingth and the coefficient of pressure loss are discussed. Specially, in the case of n=1 (Newtonian fluid), the solutions in this paper are completely identical with those in Ref[2]. |
