| 摘 要： | 从简化均匀圆管脉动流动的Navier-stokes运动方程出发,避开了Bessel函数的复杂推导和繁琐的函数表格,得到比Womersley脉动流方程更为直接和简单的解析形式,为用脉搏波进行血流计算提供一个简便而实用的分析方法。

| Abstract: | I Under certain simplifying assumptions, an approximation of the relationship between the pulse pressure-gradient and volume flow in uniform cylindrical tube is derived in this paper, its formula is simpler and clearer than the Womersley equation. And the results are accurate enough to be used in practical application. |
