摘要
从复杂的动脉血管系构造中所抽象简化出的物理模型出发，运用泊萧叶（Ｐｏｉｓｅｕｉｌｅ）定律、血管系的最优原理以及血管系Ｙ形分岔结构理论，导出了生理条件下体循环中动脉血管系内平均血压与流阻随血管分枝级数的变化而变化的分布函数，是对体循环中动脉血管系内平均血压与流阻随管径的减小而变化的实验规律作数学上解释的一个尝试．
On the basis of physical model abstracted and simplified from the complicated structure of arterial system,this paper gives a distribution function describing regularity about mean blood pressure and folwing resistance with branching series of blood vessel in arterial system in systematic circulation under physiological condition by using Poiseuille's law,most excellent principle and branching theory on Y type bifurcate structure of blood vessel system.It is an attempt to analyze mathematically experimental regularity about mean blood pressure and flowing resistance changing with decrease of internal diameter of blood vessel.
