摘要
本文应用普遍的能量方程对Ｓｔａｒｌｉｎｇ阻力器中的流体动力学问题进行了理论研究。导出了可坍陷管中午顿流体定常流动的压强－流量积分关系式；指出：瀑布模型仅适合于Ｓｔａｒｌｉｎｇ阻力器中的低雷诺数流动。此结论与Ｌｙｏｎ等人的实验结果一致。
Using the general energy equation,fluid dynamics in a Starling resistor wasstudied theoretically. The pressure-flow integral relationship for steady flow ofa Newtonian fluid in a collapsible tube was deduced. The results showed that thewater,fall model is adequate to describe the flow in a Starling resistor only atvery low Reynolds' numbers, which is in agreement with experiments of Lyon,et al.
