Mine ventilation system is a multi-variable complex system, in which a roadway may result in changes in the parameters and their relative Boundary more than the wind tunnel and even the whole network of air volume changes; On the contrary, in order to make a certain amount of a wind tunnel to reach a certain required value, but also by a number of roadways in other regulatory measures taken to achieve.

矿井通风系统是一个多变量的复杂系统，其中一条巷道参数的改变可能导致与其相关的多条巷道甚至整个风网的风量发生变化；反之，要想使某一条巷道的风量达到某一要求值，也可以通过在其它若干条巷道内采取调节措施来实现。

It is found that: the standard Model can be used to predict flows at the station and resultant velocity and temperature field under some reasonable presumptions; the impact brought by stopcock wind is variable according to the different tunnel structures; the temperature of is related with the distribution of heat load; the VAV system has advantage in energy saving, but when the air volume reduced to a certain degree, we should consider the alteration of rising the temperature of supply air, and increasing the quantity of it.

研究表明：采用合理的假设，标准的湍流模型能够较为准确地模拟和预测地铁站台的温度场与速度场；活塞风对站台的影响随区间形式的不同而不同；空调送风温度的设定与负荷的分布情况有密切的关系；针对站台空调季全天的负荷变化，VAV环控方案可以达到节能的目的，但在风量过小时，适当考虑采用提高送风温度，加大送风量的方法进行局部的调整。

The results show that for the single-track shield tunnel in actual projects,the longitudinal ventilation velocity of 2.6~2.9 m/s can effectively prevent smoke from counter flow at a heat release rate of 10 MW;when the tunnel sector on fire with a longitudinal velocity of 2.9 m/s and the unfired tunnel sector with the velocity of 1~1.5 m/s from both ends,there is an air flow with the velocity of 6 m/s ...

模拟分析得出，对于地铁实际工程中的单线盾构圆形隧道，在10 MW火灾强度下，着火区间隧道内2.6~2.9 m/s左右的纵向风速可以有效阻止烟气发生逆流；在着火区间隧道2.9 m/s的纵向风速下，未着火区间隧道两端对送送风速度为1~1.5 m/s时，联络通道内有风速为6 m/s左右的气流流向着火区间隧道，可有效抑制烟气通过联络通道向未着火区间隧道蔓延，保证人员的安全疏散。

Monitoring of the shrink tunnel area is made possible by using air curtains in the infeed and outfeed areas of the tunnel.

监测收缩隧道区的办法是使用空气幕在进料和outfeed领域的隧道。

An uninterrupted flow of air circulates from the upper area of the shrink tunnel infeed and outfeed to the lower area of the shrink tunnel infeed and outfeed.

源源不断的空气流通，从上游地区的收缩隧道料和outfeed较低地区的收缩隧道料和outfeed 。

He sugggested that a double raiway tunnel should be built . This woold solve the problem of ventilation, for if a train entered this tunnel , it would draw in fresh air behind it .

他建议一条双轨道的隧道，这样就可以解决通风问题，因为如果一列火车开进隧道，它后面就会带进新鲜空气。

Gourd-shaped cavity was due to the wind tunnel cave open at both ends of the North-South pairs to wear again and hoisted mid-air, to the north,"Xianggui corridor", Nantong bridge between mountains and ocean ridge,"Gap Road", the air in this form.

洞形呈葫芦状，由于风洞两端洞体敞开又南北对穿且高悬半空，北接&湘桂走廊&，南通架桥岭与海洋山之间的&峡道&，空气在此形成强烈的对流，故名&风洞&，于是桂林人又把叠彩山称为&风洞山&。
