部分压力

The negative pressure is a result of a penstock valve closure and only occurs in a small section of the penstock immediately downstream of the valve.

负压力的产生是由于水道阀关闭的结果，并且只发生在位于阀下游的一小部分水道中。

A given tectonic force may be resolved into two parts: homogeneous stress and differential stress. Homogeneous stress refers to isotopic pressure,which is superimposed on the original pressure and affects the equilibrium of various chemical reactions. It is also a factor that influences petrogenesis,metallogenesis and metamorphism.

构造力可以分解为两部分一部分是均应力，指各向相等的应力，它叠加在原有压力之上，并且影响着各种化学反应的平衡，也是成岩、成矿和变质作用的影响因素。

The degree that the strainer blocks up may show out on the piezometer in filtering oil vehicle running process , respond to the strainer cleaning or changing a strainer in time (to have all filtering oil vehicle special use but be for replacement's using while pressure reaches 0.35 MPa,order if necessaries is other), Gage pressure continues rising when exceeding 0.4 MPa , just meeting proper motion opens a relief valve , part oil liquid essence fliteration does not pass henceforth , returns to an oil pump directly attract the oil cavity, therefore filtering oil vehicle output rate of flow just is able to come down, to play filter oil vehicle's to avoiding damaging role.

在滤油车运行过程中滤芯堵塞的程度可在压力表上显示出，当压力达到0.35MPa时，应及时清洗或更换滤芯(备有滤油车专用滤芯可供更换用，如需可另外订购)，表压继续上升超过0.4MPa时，安全阀便会自行开启，此后部分油液不经过精过滤，直接回到油泵吸油腔，所以滤油车的输出流量便会下降，以起到避免损坏滤油车的作用。

By providing a high abundance of food and shelter, and low predation pressure, mangroves form an ideal habitat for a variety of aquatic animals, during part or all of their life cycles.

可见，食物来源丰富、隐蔽性强、捕食压力低等特点使得红树林成为水生动物的理想栖息地，许多水生动物选择在其中度过部分或完整生活史。

Deep drawsmay be made on single-action dies,where the pressure on the blankholder is more evenly controlled by a die cushion or pad attached to the bed of the press,The typical construction of such a die is shown in Figure 10-6.this is an inverted die with the punch on the die's lower portion

深drawsmay作出对单动去世后，那里的压力就压边的是，更多的控制，由一个模垫或垫附于床的新闻，典型建筑这样一个死硬的是表现在图10 - 6.this是一个倒模与冲床对模具的上半部分。

Circular and catenary always represent the shapes of minor principal stress soil arch between two parallel walls, but which shape should be used in the calculation of active earth pressure on two parallel walls remains disputed. Considering fully developed wall friction or partially developed wall friction, circular and catenary, the two shapes of minor principal stress soil arch between two parallel walls are theoretically analyzed. According to the shapes of soil arch, the coefficients of earth pressure corresponding to different angle of internal friction and that of wall friction are obtained, and the formula of active earth pressure on two parallel walls is derived.

鉴于计算平行墙间侧土压力时关于土体小主应力拱形的选择尚存在争议，考虑墙土摩擦角充分发挥和部分发挥两种情况，对平行墙间土体小主应力圆弧拱和悬链线拱分别进行了分析，得到了对应于不同内摩擦角和墙土摩擦角的侧上压力系数，以及平行墙间侧上压力的理论公式。

The lever is designed as a proportional and amplifying part in order to coordinate the transmitted force and control the length reductionXt2and then accordingly control the pressurep1continuously.

系统的核心部分是一个专用先导式溢流阀，它起到根据控制信号调节系统压力p1的作用，实现机—液的转换。

Inflation under control, PPI level down, and some degree of reduced production and operating cost pressures, while fiscal and monetary policy adjustments will increase support for the development of enterprises in order to maintain a stable economy rapid development and increase of the CPI continued to fall.

通货膨胀得到控制，生产者价格指数水平大幅下降，部分程度的降低了生产和经营成本压力，而财政和货币政策调整将增加企业的发展支持，以保持经济稳定快速发展和增加消费物价指数持续下跌。

METHODS: The auxometric nerve root retractor consisted of retractors with pressoreceptor, clamp stand and display unit.

测力神经根拉钩由带压力感受器的拉钩、固定支架和显示器3部分组成。

Indeed, jokes Mr Grundfest, it is a wonder that the Martha Stewart solution—which lets the boss do the fun parts of the job while a "chief sacrificial lamb" shoulders the legal burdens—has not already become the norm.

Joe Grundfest确实是在开玩笑，Martha Stewart的解决方法——让老板做工作有意思的部分而"主要牺牲的羔羊"承受巨大的压力——是个奇迹，但是还没有变成准则。
