1.
Experimental research on pressure drag of the double container car passing through tunnel;
双层集装箱列车过隧道空气压差阻力实验研究
2.
a passive base-bleed method for reducing drag of bluff-body vehicles is proposed,in which a proper through hole is made in the lower part of the vehicles to have the "higher pressure" air in front of the vehicle flow to its"lower pressure" base region passing though the hole,thus reduce the pressure drag on the vehicle and the fuel consumption.
为了减小车辆阻力,提高燃油利用率,提出了一种钝尾车辆的被动通风减阻方法,即在钝尾车辆的下部适当部位开一个适当尺寸的通孔,以便为均衡车体前后的压力提供一个通道,当车辆行驶时,使得车体前部的"高压"气体能够通过这个孔流到相对"低压"的车体底部区域,从而减少车辆的压差阻力以降低燃油消耗。
3.
The theoretical analysis and experimental results show that boundary layer separation will produce pressure drag.
理论分析和实验的结果说明:边界层分离将引起压差阻力。
补充资料：肺循环阻力(或全肺阻力)
肺循环阻力(或全肺阻力)
pulmonary circulation resistance
血液在肺部血管内流动时和血管壁之间的摩擦力和血液内部的摩擦阻力。肺动脉管壁较薄，分支短而管径大，故肺动脉的可扩性较大，对血流的阻力很小，仅0.12PRU(外周阻力单位)。肺循环动脉部分总的阻力和静脉部分总的阻力相等，故血液流动时在动脉部分的压力降落和静脉部分的压力降落相等。
