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, diaphragm the 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 air compressors idling.

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。

But the kind cooking cooked food with household the fuel wastages , edible oil sigmatism amounts, and quantity be increasing by unceasingly; Furniture waits for civil chemical products to enter a family with the fact that a great quantity is able to wield various building material , decoration material , artificial board sending out hazardous wastes , people increases by in interior the kind contacting hazardous wastes and quantity than in the past obvious , that interior air is difficult how to handle?

但随着家用燃料的消耗量、食用油的使用量、烹调菜肴的种类和数量都在不断地增加；随着大量能够挥发出有害物质的各种建筑材料、装饰材料、人造板家具等民用化工产品进入家庭，人们在室内接触有害物质的种类和数量比以往明显增多，那室内空气不好怎么办？于是就有空气清新器、空气清新剂、空气加湿器……等一堆科技成果不断应用，这表面上让人感觉放心、方便、舒适了，可实际上是降低了人体的自我保护能力。

BSpatial characterization of laser induced Cu plasma in air with different laser focusing distancesThe plasma spectra induced by pulsed laser ablation of copper target are measured. By adjusting the distance of the len-sample, the spectrum of air spark plasma、 Cu plasma and the reciprocity of both plasmas are analysed. From the result, it has been shown that the focusing of the laser beam has an important infunence to analyse the properties of the sample.

b 不同的激光焦点位置产生的等离子体光谱的空间特性研究激光烧蚀置于空气中的Cu靶产生等离子体，通过调节透镜与Cu靶的距离，本文观测了激光烧蚀空气产生的空气火花等离子体、激光直接烧蚀铜靶产生Cu等离子体以及空气火花等离子体与Cu等离子体相互作用等不同情况下的激光诱导击穿发射光谱，激光束焦点的位置在分析材料性质的过程中有着重要的影响。

Bioclimatic architecture realizes low energy-consumption natural ventilation: the squama-curtain of TBA TOWER has opening window and special ventilation fan, realizing air ventilation across both sides of the mansion through pressure difference between windward side and leeward side, under the condition of no pressure difference, it can form chimney effect through vacant areas in the mansion, create negative pressure in the internal capsule, import air into device layer and discharge it, realizing the circulation of fresh air, not only saving energy and improving air quality in the room, but also bringing benefits to the health and mind of inhabitants.

生物气候建筑实现低能耗自然通风：TBA TOWER鱼鳞状外幕墙设计有开启扇及专有的通风器，通过建筑迎风面与背风面的压力差实现建筑两面的窗户空气流通；在没有两面压差的情况下，可通过建筑内的挑空区形成烟囱效应，在内囊造成负压，将空气引入设备层排出，实现新鲜空气的流通，既节能、又可改善室内空气品质，利于居者的身心健康

More experimental data of condensation heat transfer coefficient, especially ones obtained at some determined pressure of mixtures and concentration of noncondensable gases, are required in order to make a data bank. Therefore, the experiment is arranged for steam-air condensing on the outside of a horizontal smooth tube, and 405 data have been obtained for the pressure of the bulk mixture covering 0.1～0.5bar and the mass fraction of air 0.3%～10.0%.

Deep grand of far water shade drop in temperature principle: Water shade and fan install the two sides wall in workshop respectively, when fan convulsions, make the air of workshop forms negative pressure, the not saturated air outside forcing workshop sheds the surface with classics water poriferous and wet shade, cause moisture to evaporate absorb a large number of latent heat, drop the temperature of air oneself thereby, below the action of fan, the humid air of these temperature that be redu

深弘远水帘的降冷元理：水帘微风机分别装在车间的双面墙头，风机抽风时，使车间的空气air产生负压，强使车间外未饱满的空气air流经水帘多孔湿滑的外面，引发水份辉发吸收非常多潜热，进而下降空气air本身的温度，在风机的作用以及影晌下，这一些被下降温度的湿滑空气air就涛涛不停的步入车间。
