压力中心

CENTRIFUGAL FLOW COMPRESSOR, A type of compressor in which air is taken into the center of the impeller and is slung outward centrifugally into a diffuser where it is slowed and pressure is increased.

离心式压气机，压气机的一种。当进气到达叶轮中心时，被叶轮离心抛出进人扩散器。在扩散器中气体流速减慢，压力增加。

The following are the expressionsfor the mean pressure set up at the detection plate and for the time of the signal toprogagate from the radiator to the detector:这里是1个公式,省略） where Re is the real part of the expression appearing within the braces, 0 is the density ofthe medium, vo is the amplitude of the vibrational velocity, c is the speed of sound in themedium, d2 = I +(r/zcos 8, z is the distance between the emitting and receiving plates, B is the angle between the axis of the acoustic channel andthe axis of the tube, r = vro/c, v is the flow speed of the fluid, d is thediameter of the pipe, m is the circular frequency, k is the wave number,where a is the radius of the plate (this is taken as the same for the emitting and receivingplates for simplicity, but there is no difficulty in discussing plates differ~mg in radii),,~ is the vibrational frequency of the emitting plate, andThe triple sums in the expressions for N~ and N2 may be neglected if the flow speed islow, since the contributions for these become negligible.

以下是表达式平均压力为定于检测板和为信号时间progagate从散热器到探测器：（这里是1个公式，省略）假如再是出现在大括号表达式的实部，0是密度中期，沃是速度的振动幅度，C是健全的速度中，D2中=我+的导向8，z是对之间的距离发射与接收板，B是声之间的通道轴角该管的轴，R =中心内大多分为/荤，v是流体的流动速度，，D是管道直径，m是圆频率，k是波数，的其中一盘是半径（这是为重点，同样的发射与接收为le简单板，但没有讨论板的困难，在半径不同毫克），，是发光板振动频率，和在N的表达式的三重总结和N2可以忽略，如果流速低，因为这些变得微不足道的贡献。

Methods: This was a cross-sectional single-center study. Between April 2008 and December 2008, consecutive dyspeptic outpatients were evaluated with standard Rome III diagnostic questionnaire.

研究目的：比较功能性消化不良不同次分类的病人，其精神病理压力与人格特质是否不同研究方法：这是单一中心的横断面研究。

Fracture experiments under biaxial loading and theoretical analysis are used to study the fracture behaviour of cruciform specimen of 16 MnR with a central penetrated ⅠⅡ mixed mode crack. A ⅠⅡ mixed mode crack J integral criterion is explored.

通过理论分析和双轴向断裂试验，对我国压力容器常用钢16MnR所制成的含中心穿透Ⅰ－Ⅱ复合型裂纹十字形试样的断裂规律进行了试验研究，探讨了Ⅰ－Ⅱ复合型裂纹J积分断裂准则。

Throughout the country schools are under economic pressure to become job-training centers and employment agencies.

在经济发展的压力下，全国许多大学成了职业培训中心或就业市场机构。

Throughout the country schools are undereconomic pressure to become job-training centers and employment agencies.

在经济发展的压力下，全国许多大学成了职业培训中心或就业市场机构。

The center left plot shows the pressure distribution and beneath that is plotted the Mach number distribution.

中心左侧的阴谋显示，压力分布和下方是策划马赫数分布。

Off-centered lacing optimises pressure distribution upon impact and reduces ball impact forces to the center of the foot whereas the revolutionary anatomically shaped AptoLast sets a benchmark in football footwear comfort.

客为本系鞋带优化压力分布的影响后，并降低球的冲击力，以该中心的脚下，而革命解剖形aptolast设定基准，在足球鞋类舒适度。

The research on achievement motivation, professional development, social recognition and economic income of physical education teachers has significant influence on setup policy, adjust the incentive style and promote their working enthusiasm.

长期以来，普通高校的体育教师管理工作主要集中在教师的选聘、任用、培训、考核等方面，这些工作都是以任务为中心，忽略了人的存在，体育教师在工作中的压力、紧张、焦虑和不满极少受到关注。

Conversely,if the heartland complex were capable of deterring a nuclear attack by possession of equal or superior nuclear systems ,its then corresponding influence over its non-nuclear or nuclear-inferior rimland neighbors would be correspondingly greater.

相反，如果受打击的中心地区的防护掩体拥有能够抵御一次核打击的相同或更高级的核保障系统的话，那么其对于无核或核落后的相邻地区的造成的相应的压力会比拥有核打击更大。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
