Using above theory,the possibitlity of recovery without pump is discussed for condensation of the steam to water with low pressure and high temperature.

本文分析了高温饱和水在满管流动的爬高过程中，其密度发生明显变化的动态机理，利用此动态特性，就实现低压高温凝结水无泵回收的可能性进行分析讨论。

To avoid the complications of tradional pumped,venous-arterial extracorporeal membrane oxygenation ECMO,a pumpless extracorporeal membrane oxygention(pECMO) was established.

对无泵驱动的动-静脉途径体外膜肺氧合支持疗法进行分析总结,并与需泵驱动的静-动脉体外膜肺氧合支持疗法进行对比,结果证明体外膜肺氧合支持疗法采取动-静脉途径比静-动脉体途径更有利。
