空气流动

HBsAg has been found in all body secretions and excretions.

病毒的传染性会被肠内黏膜分泌或细菌分泌的酶破坏，没有令人信服的迹象表明空气流动传播的发生和粪便作为传染源。

Roses are susceptible to mildew and funguses, therefore plant where there is good air movement in order to help the foliage stay dry.

玫瑰易霉变和真菌、因此植物有良好的空气流动，来帮助叶留干。

It's still a single overhead cam design and uses fins and air movement to keep things within operating temps.

它还是一个单一的间接凸轮的设计和使用鳍和空气流动，以保持内部经营的时代。

The pressure drop of airflow consisting of pressure drop of the perforated plate and liquid-layer is mainly influenced by the plate dimension and bare tower velocity, with the increasing of bare tower velocity, pressure drop of the perforated plate increases. The experimental data are used to develop a correlation as follows:ΔpD＝1.04×10－82g This correlation should be used whenβ＜5％,0.299m/s＜u＜

空气流动的阻力主要由孔板阻力和液层阻力组成，孔板阻力主要受多孔板的几何尺寸及空塔速度的影响，空塔速度越大，孔板阻力越大，对实验数据进行回归分析得出的实验关联式为：ΔpD＝1.04×10－82g 公式适用范围：β＜5％，0.299m/s＜u＜

In the breeding process of poultry and livestock, diseases are spread mainly in two ways: 1. Disease enters the alimentary tract from drinking water; 2. Air flow causes disease spreading in respiratory tract.

在畜禽养殖过程中疾病多发的传播有两个渠道：一是由饮水进入消化道；二是呼吸道由空气流动引发的疾病传播。

Particular attention has been paid to the flow of air beneath the car, with a smooth underfloor, wheel spats and wing-shaped vertical fins contributing to the control of vertical body movement and optimisation of front and rear lift coefficients.

特别注意了对汽车下方的空气流动，以顺利地板下，车轮的争吵和机翼形有助于身体垂直运动和前后升力系数的优化控制垂直尾翼。

As a result, air flows faster over the top of the wing .

因此，空气流动速度超过上方的机翼。

In the following, the paper lists node flux balance equation group and loop pressure balance equation group, based on law of conservation of mass and law of conservation of energy, and the relation between flux and pressure elicits, using the law of branch ventilation resistance and the relation of fan performance.

本文根据水电站地下洞室群通风系统的特点，提出了进行节点、分支划分与网络图绘制及分支阻抗计算的原则和方法，利用图论的相关理论将通风系统转化成为点和有向线段表示表示的，并且各个分支影响空气流动的因素由分支的阻抗表示的水电站地下洞室群通风网络图。

I wanna be I wanna be I wanna be just like a melody just like a simple sound like in harmony I wanna be I wanna be I wanna be just like the sky just fly so far away to another place to be away from all to be one of everything I wanna be I wanna be I wanna be just like the wind just flowing in the air through an open space I wanna be I wanna be I wanna be just like the sea just swaying in the water so to be at ease to be away from all to be one of everything I wanna be I wanna be I wanna be just like a melody just like a simple sound like in harmony 和 Shift the future! Work on the moon!

想要当我想要当我想要像一首曲子仅仅像一种简单的声音相似的和谐地我想要当我想要当我想要像天空仅仅在如此远处飞到另外的一个地方远离全部是一每件事物我想要当我想要当我想要像风仅仅在空气流动透过开着的空间我想要当我想要当我想要像海洋仅仅在水使摇动因此在安逸远离全部是一每件事物我想要当我想要当我想要像一首曲子仅仅像一种简单的声音相似的和谐地在月亮上工作！

As well-known, the physical law as a guide of designing MVAC systems mainly roots in numerical and experimental studies on indoor air velocity and temperature fields in test or fullscale rooms.

目前设计通风空调系统的理论依据即室内空气流动规律性，主要是靠数值模拟或者是在小气候实验室及典型通风房间内测量分析温度场和速度场得到的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
