In september 2001 , the department arranged with the electrical and mechanical services department emsd to adjust the fresh air intake and air balance of its air conditioning and ventilation systems in the revenue tower 2001年9月，机电工程署为本局筹划改善税务大楼的空调和抽风系统，调节新鲜空气的进气量和空气平衡状况。
Gea delbag lufttechnik gmbh is a special partner in the following areas : suction systems and air intake systems in addition dedusting devices as well as for other services Gea delbag lufttechnik gmbh是一家现代化的、可靠的专门产品供应商，这家供应商从事吸附系统,除尘器,吸气系统,空调和通风技术,空气-除尘技术,其它服务的制造、销售。
However if it does , the waterproof taped and reinforced seams and the incorporated silicon valve design behind the air intakes along the kite ' s leading edge trap the air inside the kite , and make it very hard for water to get in 但是如果它,防水录音的和被加强的缝和被合并的硅阀门设计在进气孔之后沿风筝的前沿陷井空气在风筝里面,并且使它非常坚硬使水进货。
Ferrari say the lip is a functional part of the air intake system for brake cooling and that its profile remains the same , regardless of whether the wheel is moving - hence it is not effectively ' moveable ' 法拉利则表示这个气阀只是用来冷却煞车的通风系统中一个起作用的零件而已，不论轮胎是否正在转动，它的形状都不会改变，所以事实上这个气阀并不会移动。
It is worthy of paying attention to the situation that there is no fresh air intake except window air conditionings . with the higher gas tightness of tenement , such air condition will doubtless bring the very disadvantageous influence to the health of people 而且值得关注的是家用空调器除了部分窗机外几乎都没有新风引入装置,住宅的密闭性不断加强,这样的空调器无疑给人们的健康带来极不利的影响。
There is a particular demand for polyamide as a material for use under the bonnet owing to the mechanical and thermal conditions found there : the cooling system , air intake system , mechanical parts , electrical circuit components , as well as external and internal parts 归功于它的卓越的机械性能和耐热性，聚酰胺材料特别在汽车发动机区域得到广泛的应用：制冷系统，进气系统，机械部件，电路部件，以及外部和内部件。到
In our recent school projects , fresh air pre - conditioners are incorporated into the air - conditioning system . this mechanism ensures good air quality by supplying adequate fresh air while at the same time utilizing the exhaust air to pre - cool ( in the hot season ) or pre - heat ( in the cold season ) the fresh air intake 近期的学校工程项目，均在空调系统加入鲜风预调机，一方面输入充足新鲜空气维持良好的室内空气质素，同时亦利用抽出的室内废气去预调新鲜空气的温度，夏天时可预先将空气降温，冬天则可预先加暖。
In addition to a longer nose , aerodynamic modifications feature kfir - style small nose side - strakes to prevent yaw departure at high aoa , a pair of fixed delta canards on the upper parts of the air intakes , dog - tooth outboard leading - edge extensions , and short fences replacing leading - edge slots 除了一个加长的机鼻外，气动布局的修改包括：在机鼻两则装上可以防止在高攻角下脱离偏航的“幼狮”式小边条，一对固定在进气道的三角鸭翼，锯齿型外翼前缘，和代替前缘翼槽的短翼刀。
In this paper , simple reacting flow model in solid - propellant ducted rocket combustor based on eddy break - up model is established . the model is used to simulate the three - dimensional combustion flowfields in an experimental motor . some factors how to affect the combustion efficiency are discussed in the paper , including air intake and gas generator nozzle 本文基于简单反应的旋涡分裂模型，建立了固体火箭冲压发动机补燃室内的湍流燃烧模型，并在该模型下对某实验发动机进行了三维数值模拟，研究了补燃室设计参数包括进气道出口设计参数和燃气发生器喷管设计参数对燃烧效率的影响。
With very large of air intake , gas turbine has more strict desalted requirements , not only for desalting effect but for resistance and size of desalting devices . in this thesis , marine moisture separators used for desalting are simulated numerically and corresponding experimental study are made . thus , we can offer references for design and manufacture of high - powered marine monisture separators 目前国内外有许多大型水面舰船都装备了燃气轮机动力，进气量极大的燃气轮机对进气的除盐要求更为严格，不仅体现在除盐的效果上，同时也对除盐装置的阻力和尺寸等提出较为严格的要求。
