压缩空气

The check valve avoids refluence of air in pipe- lines and consequent pressure loss in which compressed air is intended to flow in one direction only.

单向阀能防止管路中的空气回流，以及随之而来的因压缩空气朝这一方向流动而产生的压力损失。

The maximum run-out distance is 3200m. The three cases are studied from the Niuquangou rockslide-debris flow at the south west segment of the main seismic fault, the Chengxi rockslide at the middle segment of the main seismic fault and the Donghekou rockslide-debris flow at the north east segment of the main seismic fault.The three cases illustrates following common characteristics:(1)parent rockmass is broken under long geologic processing and weathered;(2) Rockmass was separately expanded and thrown under long-period strong ground vibration in which the vertical motion was predominant along the main seismic fault;(3)sliding mass was crashed at the exiting zone and transferred to fragment material;(4) The secondary landslide was triggered underneath the exiting zone due to the powerful crashing and shaving processes that provides more mass to debris body and cushion shape;(5) The a long run-out distance fragment flow is occurred under air layer lubrication. The air layer was pressed and turbulently flowed in the narrow-shaped valley, or laminarly flowed in the extensive flatland.

本文重点解剖了位于地震破裂带南西段的汶川映秀牛圈沟滑坡-碎屑流、位于地震破裂带中段的北川城西滑坡和位于地震破裂带北东段青川东河口滑坡-碎屑流3个典型实例，认为具有如下特征：1）岩性条件：母岩遭受长期构造动力作用，呈碎裂岩体，后期被强烈风化，岩体极为破碎；(2）抛掷效应：位于汶川地震主断裂带或附近，垂直加速度大于水平加速度，强地面运动持时长，岩体发生振胀和抛掷；3）碰撞效应：上部滑坡体发生高位剪出和高位撞击，致使岩体碎屑化；(4）铲刮效应：撞击作用导致下部山体被铲刮，形成次级滑坡，为碎屑流体提供了足够展翼和抛洒物源体积；5）气垫效应：碎屑化岩体快速抛掷导致下部沟谷空气迅速谷状圈闭和向下紊流，形成气垫效应，或者，在下部地形开阔地带压缩空气呈层流状态致使滑体凌空飞行。

Pressure governor valve is the use of a spring-loaded power and pressure balance theory, when the spring-loaded pressure less than atmospheric pressure and the valves closed when the pressure is greater than the spring-loaded rubber tubing stretch when the bottom of compressed air diaphragm, diaphragmthe effort to promote diaphragm upward and left vavle seat blow the air flow of gas, this would piston shirking role in the pressure mobile, Selection will be emissions from valve seat, air compressors made by the then air into the gas valves and exhaust emissions is through the mouth into atmospheric

调压阀的原理是利用了弹簧力与压力相平衡的原理，当弹簧的压力小于气压的时候阀关闭，当压力大于弹簧的弹力时候橡胶调压膜片下方的压缩空气对膜片的作用力，推动膜片向上拱曲离开阀座而使空气流入气腔，此时卸荷活塞在气压作用下移动，将排放阀门推离阀座，于是由空气压缩机充入气腔的空气便通过排放阀和排气口排入大气空气压缩机空转。

If a diver is safety conscious, then they will approach their diving with conservatism. They won't push depth and time limits, just to do a dive.

注意安全的潜水者会比较保守，潜水的时候绝不会把压缩空气和免减压时间耗尽。

Compressed air entering the air net is always100% saturated with water vapour.

通常进入空气网的压缩空气都含有百分之百的水蒸汽。

In these regulations 'blasting process' means the cleaning, smoothing, roughening or removing of part of the surface of any substance or thing including granite, stone or brick by the use as an abrasive of a jet of sand, metal shot or grit or other material propelled by a blast of compressed air or steam or water or by a wheel.

在本规例中，"喷砂工序"指使用喷射砂粒、金属砂或粗砂或其他物料作为磨料，并以喷出压缩空气或水蒸汽或水或利用轮推动磨料的喷射，从而清洁、磨滑、磨粗或除去任何物质或物件(包括花岗岩、石块或砖块)的部分表面的工序。

Plasma cutting machine work, the first plasma arc ignition by high-frequency oscillator excited between the electrode and the inner wall of the gas nozzle, resulting in high-frequency discharge, the gas ionization and the formation of local small arc, this small arc by the compressed air role, from the nozzle to ignite plasmon in the arc, spark generator, which is the main task.

等离子切割机工作时，首先要引燃等离子弧，由高频振荡器激发电极与喷嘴内壁之间的气体，产生高频放电，使气体局部电离而形成小弧，这一小弧受压缩空气的作用，从喷嘴喷出以引燃等离于弧，这是火花发生器主要的任务。

"Shotcrete is a mixture of portland cement, aggregate, and water conveyed by compressed air to a spray gun."

喷制混凝土是一种混凝料与普通水泥的混合物，由压缩空气输送到喷枪的喷嘴处。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
