For recording in a common quiet office using a uni-directional microphone, the volume of voiced sounds is larger than that of unvoiced sounds, and the volume of unvoiced sounds is also larger than that of environmental noise.

一般而言，有声音的音量大於气音的音量，而气音的音量又大於杂讯的音量。是一个相对性的指标，受到麦克风设定的影响很大。

The results of this study indicate that changing the angle of the intake port has a profound effect on the flow field during the intake stroke of the engine cycle. For the case with the intake-exhaust valves canted at zero degree (the so-called vertical valves), the tumble ratio, swirl ratio, turbulent intensity, and turbulent kinetic energy in the direction perpendicular to the bisecting plane of the cylinder are at their highest levels than those obtained for the other cases. This effect is most pronounced after the compression stroke of the cycle. As a result of this study, it is observed that the behavior of the overall flow field from the intake to the completion of compression stroke has a major impact on the effectiveness of the mixing of fuel-air prior to the ignition of the engine cycle.

结果显示，改变进排气阀的倾斜角度对进气期间的流场变化有很明显的影响，其中以垂直阀(进排气阀倾斜0度)所得的 Y轴向(Y方向系垂直於将汽缸对分为二平面的方向)滚流强度、涡漩比、紊流强度、紊流动能等流场强度为最强；若以流体经活塞压缩后的流场特性进行探讨，所得结果显示压缩冲程对汽缸内流场的效应是不容忽视的；因此由进气到压缩过程结束的整体流场现象，才是影响引擎点火前的油气混合程度与燃烧品质的关键。

The present invention features that fume after dedusting and heavy metal adsorption is fed via fume valve and fume-air heat exchanger to a sea water column desulfurizing system supported by a sea water supply system to eliminate SO2 and a defogging system to eliminate water content and fine dust before exhausted via draught fan and chimney. The slurry after desulfurizing and the dust is fed to an aerating, neutralizing and oxidizing system for exhaust.

其特点是，烟气经过除尘和重金属的吸附经烟气输送系统中所设烟气阀门和气气换热器进入有海水供给系统支持的海水液柱脱硫系统脱除二氧化硫，脱硫后的烟气经除雾系统去除水分和细灰再经引风机通过烟囱排出，脱硫反应后的浆液与脱除的灰尘送至曝气中和氧化系统，达标后通过管道排出。

Having species take chi from earth to ascend depletes earth of the chi necessary to foster global ascension.

有一些物种从地球获取气来提升这会掏空地球必需用来培育全球提升的气。

As a part of air intake system, intake manifolds have great effects on the distribution non-evenness of multi-cylinder engines.

进气管作为进气系统中的一部分，对多缸发动机的进气不均匀性有重要的影响。

The conducting wall in micro-tube preheats the inlet mixture by axial heat transfer. The existence of conducting wall will help to reach full reaction in the micro-tube. As the inlet velocity increases, both the existence of the surface catalytic combustion and the gas phase combustion become the limiting factors on combustion. Wall material and equivalence ratio of hydrogen/air mixture have important influence on catalytic combustion of hydrogen.

计算结果表明：表面催化反应对空间气相反应有抑制作用；在微型管道内，通过导热壁轴向间的传热，预热入口混合气体，使氢气燃烧更加充分；随着入口速度的增大，燃烧过程同时存在着表面催化反应和空间气相反应两种控制因素；管壁材料和当量比对氢气的催化燃烧过程有重要的影响。

Extra fuel must be added to the mixture so that there will be enough vaporized fuel to form

&这是因为在低温下燃油不能迅速气化，因此，要在混合气中额外增加燃油，这样才有足够气化燃料形成可燃混合气。&

However, it is unavoidable the spillage and leakage of crude oil and oil products occur in the processes of oil exploitation, refinement, transportation and application. First of all, a small amount of light hydrocarbons volatilizes into atmosphere while the others can stay in the unsaturated zone or reach groundwater table under the action of gravity and capillary pressure, which may directly or indirectly cause oil pollution of groundwater system.

但是，在石油的开采、炼制、运输和使用的过程中，不可避免地会有大量原油和石油制品抛洒或泄漏于地面，其中的一些轻质石油组分通过挥发进入大气，而绝大部分石油会在重力和毛细力的作用下渗入包气带，或者透过包气带达到地下水面，从而间接或直接地污染地下水。
