平衡压力

The centrifugal tendency of a planet and the counterpressure arising from the centrifugal tendency of the other matter composing the vortex.

轨道乃由於行星的离心倾向，以及由於组合成涡漩的其它物质之离心倾向之反压力，两者之间的平衡而构成的。

First, For the coronary artery stent, two kinds of loads, including the pressure named 〓 derivatively from the balloon and the counterforce named 〓 on the wall edge of the stent, have been taken into account in the analysis of the stent.〓 and 〓 were changing as the stent expanding. So, the expansion process of the stent could be considered as the process composing of many extremely short equilibrium processes, where 〓 and 〓 could be regarded as constants and the stresses, the strains and the displacements were obtained using NFEA in every processes. Then, the stresses, the strains and the displacements obtained in every processes or steps were added up to get the final structure of the coronary stent.

首先，解决了支架有限元分析的载荷非线性问题，认为医用心血管支架受到两种载荷的作用：球囊直接传递的压力〓和球囊对不锈钢支架丝壁边缘的反作用力〓，这两种载荷在支架分析中必须都考虑进去；〓为非线性载荷，随着支架扩张不断变化，处理时将支架扩张的整个过程看成由37个很短的平衡过程组成，在每个过程中取〓为常量，采用有限元法获得应力、应变、位移，最后将各过程的应力、应变、位移迭加起来就获得了不锈钢支架总的应力、应变和位移；本研究用变分法和有限元法模拟杆件拉伸证明了上述方法是合理的。

阀杆防爆出装置。◇钢球上设计有压力平衡孔。◇双层阀杆填料与两片蝶性弹片装置。◇阀体上设计清洁阀腔装置。

Among them dissolve medicine pinhead is double-barreled type construction, side canal has a side opening each up and down, be helpful for a balance store the pressure inside medicine bottle.

其中溶药针头为双管式结构，侧管上下各有一侧孔，有利于平衡储药瓶内的压力。

If two or more containers are manifolded, the vent valves should also be connected together to ensure pressure equilibration between all the containers.

如果把两个或更多容器并联在一起，排气阀也应该连接在一起，以确保所有容器之间的压力平衡。

With the system pressure dropped,the nitrogen adsorption equilibrium constant of the activated carbon increased.

随反应体系压力的下降，所得活性炭对氮气的吸附平衡常数增大。

Equilibrium constant of three reactions and equilibrium conversion of every reaction in various temperature and pressure, various ratio of H〓 to CO are calculated.

随后对各个反应在不同的原料气比例，不同的温度和压力下的平衡转化率进行了计算。

There is growing recognition that mineral structures can form and deform at much milder pressures and temperatures than their pure equilibrium phase diagram would suggest, when in contact with water or in the presence of anisotropic strain and stress ref.

正在增长这样的认识，矿物组织，在与水接触时，或在存在着各向异性应变和应力条件下，能够在它们纯净的平衡相图所建议的更温和的压力和温度下形成和变形〔参看文献143〕。

Any disturbance to the body's state of equilibrium can produce stress.

对身体平衡状态的任何干扰都可能产生压力。

Also in order to maintain the main impeller axial force balance, have to set up a vice-impeller structure, it can reduce the pressure sealed chamber so that the axial force pump and mechanical seal life expectancy are greatly increased.

另外为了保持主叶轮轴向力的平衡，须设置一个副叶轮结构，它能降低密封腔的压力，使电泵的轴向力及机械密封的寿命均大大提高。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
