查询词典 pressures

Compared with the traditional tunnel ventilation system, this system can greatly save investment and avoid the increase of running expenses arising from the greater wind pressures for ventilation fans.

One way to overcome this limitation was to use pressures greater than one atmosphere , and this was done by Thomas Savery in 1698 in a steam engine designed to pump water from mines.

克服这一局限的一个途径是采用大于一个气压的压力，1698年托马斯-萨韦里曾经将这个办法用在一台从矿井中抽水上来的蒸汽发动机之中。

In this paper, the characteristics of the spray evaporation and mixing process within a wide range of injection pressures (40MPa134MPa) were investigated in a constant volume bomb with high pressure single fuel injection by using high-speed laser shadowgraphy and schlieren photography, image processing technique as well as Malvern Droplet and Particle Sizer etc.

作者在所研制的单次可控燃油喷射系统、定容实验装置上采用高速激光阴影法和纹影法和先进的图像处理技术，同时使用Malvern粒子分析仪，在很大的喷射压力范围内对直喷式柴油机燃油的喷雾特性及其混合过程进行了系统的实验研究和理论分析。

Before and after operation, the activities of serum phospholipases A2 (PLA2)and amylasewere assayed and the basal pressures of the ducts were measured when secretin was injected.

于手术前检测各组犬的血清磷脂酶(PLA2)和淀粉酶活性及背、腹胰管基础压并在胰泌素激发后15、30、45、60和90分钟各测压一次。

If radically deflationary models of self-deception do turn out to imply that our own desires and emotions, in collusion with social pressures toward bias, lead us to hold self-deceptive beliefs and cultivate habits of self-deception of which we are unaware and from which cannot reasonably be expected to escape on our own, self-deception would still undermine autonomy, manifest character defects, obscure us from our moral engagements and the like.

如果自我欺骗的剧烈降级模式真地说明了我们自己的欲望和情绪，与带偏见的社会压力合谋下，导致了我们拥有了自我欺骗性的信念，养成了自我欺骗的习惯，这些是我们没有察觉到的并且不能合理地期望我们自己来独立摆脱，那么自我欺骗还会破坏到自主性，体现出性格缺陷，对我们掩盖起了道德约定等等。

Not only are they less able to deal with the pressures of day-to-day existence, but also their self-control and self-direction become endangered.

不仅他们应付每日生活的压力的能力会变差，他们的自我控制和自我导向能力也会受到损害。

We do not exclude such pressures being self-generated but it is simpler to regard them as arising from outside.

我们不排除内部产生的压力，但通常我们都把它看成外部产生的。

A self-luminous celestial body consisting of a mass of gas held together by its own gravity in which the energy generated by nuclear reactions in the interior is balanced by the outflow of energy to the surface, and the inward-directed gravitational forces are balanced by the outward-directed gas and radiation pressures.

星，天体：本身能发光的天体，由自身吸力吸引的大量气体组成内部核反应产生的能量流向表面，向内的引力通过逃逸的气体和放射压力相抵消来达到平衡

So long as the flow field data, velocities and pressures, are obtained for the nominal wake at the propeller disk and for the propeller slipstream downstream of the propeller disk in the self-propelling condition, the energy income and expenditure terms of the propulsion system can be calculated by making use of this method.

此方法明确指出了提高船舶推进效率的途径，特别是利用船型造成大量、均匀和有预旋的伴流可因为增加系统能量来源。

In the face of so many pressures and challenges, self-realization is the most post-80 aspirations.
