泵

The heart has four hollow chambers that work in pairs as two separate pumps. One pumps blood to the lungs to pick up oxygen, while the other pumps blood through the body to drop it off.

心脏由四个心室构成，两个一组形成独立作业的泵，一个负责把血液泵入肺脏吸取氧气；另一个则负责把血液压入身体各处。

"In the 1980's, the 6100 Series of Heavy Duty Recessed Impeller Pumps was developed to serve aggressive in-plant applications such as sludge and grit."

1980年代，莫里斯公司开发了6100系列重型凹式叶轮泵，特别适用于具有很强破坏性流体介质如软泥和粗砂的泵吸处理。

The effectiveness of inducers, vortex pumps, and special pump designs for gas extraction for up to 40 percent gas by volume are discussed.

当吸入气体容积含量达40%时，分别对吸入诱导轮、漩涡泵和特殊设计的气体处理泵进行了讨论。

This paper describes the structure and physical-mechanical properties of them and introduces their application to the eletrical motor bearings jet looms, deep well pumps, water turbogenerators, divd electrical machineries and rubber spacer pumps.

本文对它们的结构和物理性能作了比较详细的描述，并介绍了它们应用在电机轴承、喷气织布机、深井泵、水轮发电机、潜水电机和橡胶隔膜泵等机电产品上所取得的良好效果。

But because some key technologies, such as pipe system with lower loss and no vacuole, pump with high efficiency and big capability, the good combination among ship, equipment and pump, navigation sets with good hydrodynamic performance, have not been settled, the evolution of waterjet is slower.

但是由于一些技术没得到解决，如低损失、无空化进口的管道系统；高效率和大功能转换能力的推进泵；以及船、机、泵的有效配合问题；水动力性能的导航操纵装置等，影响并制约了喷水推进技术的发展。

They are redesigning the seal form of the bearing seat of granulation wheel and adding swing water ring out of the bearing seat,then lock question of the granulation wheel was solved;Enlarging the cooling area of the granulation wheel 's crust to reduce the its distortion;choosing wearable pump to reduce the malfunction.

重新设计粒化轮轴承的密封型式，并在轴承座外增加甩水环，解决了粒化轮卡死的问题；扩大了粒化轮外壳的冷却面积，减少了粒化轮外壳的变形；改用耐磨泵减小了泵的故障。

Experiment results indicate that the magnetic fluid flux has a direct relation with the magnetic field under the effect of traveling wave magnetic field. The bigger the magnetic field is, the more the flux is, when the structure of the magnetic fluid travellig pump and the saturation magnetization of magnetic fluid are constant. The volumes of the magnetic fluid from the travelling wave pump increase from 1.9 ml to 3.1 ml, when the magnetic field intensity increases from 25 900 A/m to 40 000 A/m. In addition, the change rate of the magnetic fluid decreases with the increase of the magnetic field due to the effect of magnetic field on magnetic fluid viscosity. The bigger the saturation magnetization of the magnetic fluid is, the more the flux is.

结果表明，行波磁场作用下的磁性流体流量与磁场的强度有直接关系：在磁性流体行波泵结构和磁性流体饱和磁化强度相同的条件下，磁场强度越强，其流量越大；当磁场强度从25900A/m增加到40000A/m时，单位时间内从行波泵内流出的磁性流体的体积由1.9 ml增加到3.1 ml；随着磁场强度的不断增加，磁性流体流量的变化率由于磁场对其粘度的影响而减小；而磁性流体的饱和磁化强度越大，其流量也越大。

If the external normal, they should check the wheel cylinder or master cylinder failure.

若外部正常，则应检查分泵或总泵故障。

"Other Brake Services include addition of Brake fluid, Bleeding the hydraulic system to remove air, repair or replacement of master cylinder and wheel cylinders, replacement of Brake linings, and refinishing of Brake drum s."

制动器的其它维修工作还包括：添加制动液，排出液压系统的空气，修理或更换制动总泵和分泵，更换制动衬片和整修制动鼓工作表面。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
