压过

OBJECTIVE In order to reduce the damage of negative pressure from cardiotomy suction on red blood cell and endocardium during extracorporeal circulation, we developed a cardiotomy suction relief valve and applied clinically.

目 的为了减轻体外循环心内吸引力过大，所产生的负压对红细胞和心内膜的破坏，将研制的一种心内吸引减压阀我们在临床试用。

The combination of excess pressure drop across the valve and an increase in velocity shortened the sleeve life.

阀门两端过大的压差和流速的加快的组合作用下，套管的使用寿命就会缩短。

Of Heat Energy Equipment, which solves the problem of excess pressure in compressor exhaust and promotes the energy efficiency ratio.

The wage rate structure, in fact, may become even more distorted; for the great mass of unorganized workers, whose wage rates even before the inflation were not out of line (and may even have been unduly depressed through union exclusionism), will be penalized further during the transition by the rise in prices.

事实上，工资率的结构甚至可能变得更不公平——众多没有参加工会的工人，他们的工资水平甚至在通货膨胀之前就不大符合他们应得的标准（甚至可能因为遭受工会排挤，而被压得过低），而在物价上涨的过渡期间，他们的处境将进一步恶化。

Hemofiltration was used for treatment of ARF.Conclusion This patient because of bulk drinking and long time deep slumber had muscle compressed to RM-ARF.Early diagnosis and hemofiltration treatment in time are the key point of this case to get favorable effect.

本例患者RM-ARF的发病具有急性酒精中毒及骨骼肌长时间受压而致局部肌肉发生缺血再灌注损伤两诱因，而早期诊断、及时应用血液滤过治疗是本例患者获得良好疗效的关键。

Some innovative approaches were presented to resolve the problem existing in the first generation of boost compressor by increasing the flow area of fluidics nozzle to decrease pressure drop and erosion attack, adding a new flow path in order to improve boosting effect of the second piston bore, connecting a bypass valve in parallel with throttle valve to set a partial flow and regulate pressure drop.

针对第一代样机存在的问题，提出了改进措施：①增加射流元件喷嘴过流面积来降低压耗和冲蚀破坏；②在射流元件输出道与二级活塞缸之间增加新流道，提高二级活塞缸增压效果；③在节流阀位置并联旁通阀进行分流稳压。
