在2009年矿山安全和卫生署引用了Upper Big Branch矿场多达515次，大部分都是关于其通风以及逃生路线的问题。

The MSHA cited the Massey mine for hundreds of violations in recent years, including 10 so far this year related to legal requirements for ventilation systems to control methane and highly explosive coal dust.

MSHA称，Massey Energy Co。旗下的这座煤矿近年来发生过数百起违反矿山安全规程的事件，今年迄今为止就有10起违反煤矿通风系统要求的事情发生，这一系统旨在控制矿井内甲烷和高爆炸性煤尘的浓度。

MSHA has repeatedly cited the Upper Big Branch mine for problems with its ventilation system, including two large fines in January for having dirty air flowing into an escapeway where fresh air should be, and an emergency air system flowing in the wrong direction.

MSHA的多次引用了上大与它的通风系统，包括两个大型罚款1月因不洁空气进入一个escapeway新鲜空气要流向，并紧急空运系统在错误的方向流动的问题，分矿。

The ventilation system screamed into high gear, airlocks slammed into place where the chemical breached the hull--leaving parts of the ship effectively dead--and in the chilling near-vacuum the remaining chemical couldn't react to completion with the metal on the hull.

通风制度进入高速档之内尖叫，airlocks 猛然地撞进化学者突破了壳的地方--有效地完全地离开船的部份--和在无情者中接近-用吸尘器打扫那剩余的化学无法由於在壳上的金属对完成产生反应。

Form the theory to say, if we inspect things well, controllable circulatory ventilation can bring enough fresh air to circulatory places so that coal mine can produce safely. We study the coalface 66 in Jingting coal mine.

从理论上讲，应用可控循环通风，只要监测监控措施得力，保证有足够的新鲜风量进入循环区域，则可保证在可控循环通风情况下，矿井的安全生产。

On the basis of unit method measuring data, most of gas emitting from the mine goaf in the "U" ventilation coalface accumulates near the upper corner. What is more, the upper corner is the congestion of air leakage in the whole goaf. Therefore, the local accumulation of gas is very easy formed in upper corner.

根据单元法实测如：&U&型通风工作面绝大部分从采空区涌出的瓦斯集聚在上隅角附近，而且上隅角也是整个采空区的漏风汇，因此，上隅角极易形成瓦斯积聚。

Ventilation is concerned with the supply of fresh air, the removal of contaminants and heat

通风涉及的是新鲜空气的供应，污染物和热量的排除。

You can use alternative heat, such as from a space heater, but be sure to follow all of the manufacturer recommended safeguards, and always assure proper ventilation.

你可以使用其他热源，像是小型供热器，但确认是依制造商所规定之安全指示使用，并随时注意通风。不要燃烧垃圾。

Baby my home fast for two months, and in recent days when infants are always anxious to hear a small nose breathing is not smooth voice, do not want adults rhinitis nose like ventilation, But look at the small nose鼻屎堵着no, he did not look uncomfortable, but after listening to really worry about, I do not know how else, ask experienced mothers, thank you

我家孩子快两个月了，最近几天吃奶着急的时候总是听见小鼻子呼吸有不顺畅的声音，就想大人鼻炎鼻子不通气似的，可是看看小鼻子里也没有鼻屎堵着，他也没有难受的表情，但是听了真担心，不知怎么回事，请教有经验的妈妈们，谢谢啦

The forced expiratory volume in first second(FEV1) decreased 0.03 L per year, FEV1/FVC%(FEV1%) decreased 0.151%, peak expiratory flow rate 0.118 L/s, maximal mid-expiratory flow 0.04 L/s, maximal voluntary ventilation 0.876 L, vital capacity 0.04 L. Residual volume increased 0.033 L per year, functional residual capacity 0.033 L. VC,FVC,FEV1,RV,RV/TLC of healthy elderly in the exsmoker group were significantly different from nonsmokers. The declinations of lung functions were not significant in different age group of healthy elderly.

结果 用力肺活量每年下降0.032 L，第1秒用力呼气量(FEV1)每年下降0.03 L，FEV1占用力肺活量比值（FEV1%）每年下降0.151%，呼气流量峰值每年下降0.118 L/s，最大呼气中段流量每年下降0.04 L/s，最大通气量每年下降0.876 L，肺活量每年下降0.04 L，残气容积每年升高0.033 L，功能残气量每年升高0.033 L，残气容积/肺总量每年升高0.596%。

But this is impossible, as long as it is engaging in a market economy, there are risks in any operation.

但是，这是不可能的，只要是搞市场经济，是有风险的任何行动。

We're on the same wavelength.
