空气的

According to research air quality survey shows that the international authorities: air relative humidity should be the most appropriate level of 60-70%, dry winter when the cold weather should not be less than 50% of the summer rainy season should not be more than 80%, only in the This humidity conditions, the most suitable for a variety of biological growth and storage of various objects.

据专业研究空气质量的国际权威机构调查表明：空气的相对湿度应以60-70%最为适宜，冬季天气寒冷干燥时也应不低于50%，夏季雨季时不应大于80%，只有在这种湿度状况下，才最适宜各种生物的生长和各种物体的存放。

Because temperature effects on people rather large, so many people think to measure temperature, in order to precise measurements of temperature is now some thermometer measuring air temperature can not even measure up to air humidity.

因为温度对人的影响相当的大，所以人们想了许多办法来测量温度，为了就是能够精确的测量出温度，现在有的温度计不光能测出空气温度，甚至能测量出空气的湿度。

Ultra-clean air flow rate of 24 ~ 30m/min, which are adequate to prevent possible harassment in the vicinity of air pollution caused by such a flow will not impede the use of alcohol lamp or Bunsen burner burning disinfection of equipment and so on.

超净空气的流速为24～30m/min，这已足够防止附近空气可能袭扰而引起的污染，这样的流速也不会妨碍采用酒精灯或本生灯对器械等的灼烧消毒。

So the first method is the best one, which makes use of the temperature discrepancy between brick and flue gas during initial stage of combustion to intensify burning by excess coefficient of maximum coal gas against minimum air, so that the temperature at top of arch can reach the highest specified value 1350℃ in 15-30mins.

因此较优的燃烧制度是固定煤气量调节空气的快速烧炉法，即燃烧初期利用砖温与烟气温度相差较大的时机，以最大煤气量和最小空气过剩系数来强化燃烧，尽快在15～30min内将拱顶温度烧到规定的最高值1350℃。

The principle, process, influence factors, advantages and disadvantages of dry air exsiccation in flowing gas evaporation method and the preparation of dry air are introduced mainly.

综述了天然气管道常用的干燥剂法、流动气体蒸发法和真空干燥法的原理、优缺点、影响因素，对流动气体蒸发法中的干空气干燥法的原理、工艺、影响因素、优缺点、干空气的制取进行了重点介绍。

The laminar flamelet model has been widely used in the recent years, but its application to the internal combustion engine is still scarce. The domestic investigation in this aspect is almost blank.

本文作为初步尝试，将层流小火焰模型应用于典型的柴油机扩散燃烧过程，以一台直喷式柴油机为对象，分别以碳十二烷与空气的单步反应和正庚烷与空气的多步反应为机理，以混和分数为自变量，以标量耗散率为参数，建立相空间中组分质量分数瞬时值及温度瞬时值的二维层流小火焰数据库。

The particle in the anion and air grown collides, electrifies it, the electrification particulate matter is easy to affix to the wall , the surface of mirror , floor, achieve the goal of purifying air.

另外从竹炭中产生的负离子与空气中的颗粒碰撞，使其带电，这些带电颗粒物容易附着在墙壁、镜面、地板上，达到净化空气的目的。

A numerical simulation method is used to investigate the cooling and humidifying effects of wetlands. A mixture model was adopted to simulate the flow and diffusion of air and moisture, which describes the process of heat and mass transfer.

采用数值模拟方法研究湿地对周边区域空气的降温增湿效应，建立了空气、水气的流动与扩散混合模型，描述给定空间的传热传质过程。

When the air pump shell memory, because the air density was much smaller than the density of liquid and a smaller centrifugal force.

当泵壳内存有空气，因空气的密度比液体的密度小得多而产生较小的离心力。

When the pump shell memory there is air, because air density is much less than the density of the liquid resulting from a smaller centrifugal force.

当泵壳内存有空气，因空气的密度比液体的密度小得多而产生较小的离心力。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
