| 摘 要： | 作者假设血液为符合幂定律的非牛顿流体，对小动脉血管系统进行了详细的优化分析。导出了血流量与管径立方成正比的结论以及壁面切变率与管径无关的推论。此结果既包含了前人对于牛顿血流的研究成果，又能克服后者的不足，而与近期的生理测定一致。 |
| 关 键 词： | 血流量－管径关系，幂定律流，优化分析 |

| Abstract: | Assumed the blood in arterioles is a non-Newtonian fluid governed by the power law, a detailed optimization analysis for arteriole blood vessels was conducted. A general conclusion,that(1)the blood flow is proportional to the cubic power of the vessel diameter; (2)the shear ratio of the vessel surface is independent of the vessel diameters. This result not only contained the previous research achievement on the Newtonian blood flow, but also overcome the insufficiency of it, and was identical with the recent physiological observations. |
