气流

It is of great importance to avoid nonuniformities, because a slight difference in airflow may change the behaviour of the tested object, and furthermore provide false information to the aerodynamicist, who consequently make the wrong dicisions.

这样做可以很好地避免不均匀的现象，因为任何一点气流上的轻微差别都可能影响这个测试项目，最后会给空气动力学家提供错误的数据，使他们做出错误的决定。

From this the program named as AFDC/LACS has been compiled with language FORTRAN77 and the calculation on the airflow and distribution of the place mentioned above has been done with several design conditions.

在此基础上，笔者使用FORTRAN77语言编制了名为AFDC/LACS的计算机应用程序，以标准机组段下游侧空调系统为代表，就不同空调设计工况条件进行其分层空调气流组织计算。

Thus, the heat content from the waste gases from blast heating apparatus or those arising in the afterburning of waste gas flows from tunnel driers for the removal of solvent residues can be fed back into the process via a heat transfer medium circuit to preheat the fuels and fuel air or to heat up the material to be dried.

因此，来自于废气/加热设备/燃烧形成的热气流/移走废弃的隧道干燥设备等的热量可以通过一个闭路循环的导热油把热量循环利用或者用来加热需要干燥的物质。

With the characteristic above, there are also special requests on fire resistant for the AHU, chiller and air flow, etc.

精度要求偏高。由于上述特点，因此对空调箱、制冷机、气流组织防火等的要求也具有特点。

为了解决上述弊端，采用新型空气冷却器一次换热，传热管形成高热流密度，由快速的空气流把热量散发到大气中去。纯净水在新型的空气冷却器和高频加热设备内闭路循环，被冷却系统长期不结水垢，不被异物堵塞，冬季在冷却水中加入防冻剂杜绝了水路被冻坏的故障。

Three methods are mainly used to control wind-blown sand hazard,on the basis of the understanding of the mechanisms of air flow and sandy bed.

在风沙防治中，根据气流与沙物质地表作用的机理来看，主要有三种途径。

The software of air brake system simulates instrument display, air flow and pressure change of brake system at running of locomotive.

制动系统仿真软件，模拟8K型电力机车在实际运行与操作时，制动系统的仪表显示、气流流动与压力变化的情况。

This paper conducts a numerical simulation analysis on the fluid-solid coupling of the bridge tower and air by adopting CFD approach.

本文采用CFD方法，在对桥塔进行绕流分析的基础上，还对桥塔—气流的相互作用进行了流固耦合的数值模拟分析。

Melts, if, the sky top, has no cold air, bump the shot warm air flow, that seldom

溶化，如果，天空上面，没有冷空气，去撞击暖气流，那就很少

The second cell consists of air rising in the middle latitudes—about 30 to 60 degrees north and south—and then falling again near the poles.

而第二个环流圈的气流从中纬度地区上升（大约在南北纬30-60度），并在极地附近下降。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
