Large - scale machines employed in the construction to load and transport rocks also increase poisonous gases produced per hour . so the ventilation of the tunnel itself becomes a new problem 为实现快速施工，该隧道采用大型机械装碴、运输，这些机械单位时间内产生有毒、有害气体增多，通风较为困难。
In modern plants the gases produced by combustion ( flue gases ) then pass through devices that remove particulates and oxides of sulfur and nitrogen before being exhausted via smokestacks into the air 现代的电厂中，燃烧产生的废气会再通过其他设备，去除硫与氮的颗粒及氧化物，最后才经由烟囱排入大气中。
The underwater granulator has the following structure : an exhaust extrusion machine is designed through removing the gas produced during the processing of plastics to make granules plump , stout , and smooth 本机型是较为经济，理想的塑胶造粒设备。本机最适于： abs ， ps ， ldpe ， hope ， pmma和pp等塑料的造粒生产。
In order to solve the polution problem of the toluene contained waste gas produced by the organic chemistry production process , a toluene purified recycle system based on plc and hmi is proposed 摘要为了解决有机化工生产过程中排放的甲苯废气对环境的污染问题，设计了一套由plc 、 hmi 、智能仪表构成的甲苯净化回收控制系统。
In electron storage rings , the interactions by beams with residual gas produce the bremsstrahlung which has not been sufficiently understood and is the main course of the loss of the beam 由于加速器产生高能粒子，在实际应用中必须面临辐射防护方面的问题。加速器储存环直线节中残余气体产生的轫致辐射是同步辐射装置中光束线防护的重要课题之一。
Today air liquide operates more than 550 industrial gas plants in over 60 countries on five continents . our scientists and engineers have constructed 3 , 000 industrial gas producing facilities 今天的液化空气集团拥有着分布在五大洲六十多个国家的五百五十多个工业气体生产工厂。我们的科学家和工程师已在全世界各地建造了3000多个工业气体生产装置。
Article 21 the fuel gas producing enterprise , the selling enterprise and the gas supply station shall not provide the unit or individual person holding no qualification certificate or gas supply license with fuel gas for resale 第二十一条燃气生产企业、燃气销售企业及其燃气供气站点不得向无资质证书、无供气许可证的单位和个人供应用于销售的燃气。
In order to ensure safety and credibility of the transformer , it is important to detect the component , content and speed of gas producing in the oil of transformer , to find out the potential malfunction in the transformer 基于气相色谱仪的数据检测及故障诊断系统能够准确、快速的对变压器进行故障诊断,及早发现其内部故障,减少损失,因此本系统的设计具有重要意义。
Article 16 the fuel gas selling enterprise shall make a fuel gas production and sales contract with the fuel gas producing enterprise according to the principle of guaranteed production and sales base , equality , mutual benefit and of reaching unanimity through consultation 第十六条燃气销售企业与燃气生产企业应当按照确保产销基数、平等互利和协商一致的原则，订立燃气产销合同。
