该模型克服了传统评价方法主要从辐射危害的角度进行评价的局限，能综合评价铀矿山井下空气的质量。采用该模型对某铀矿井4个用风点的空气质量进行了评价，获得了4个用风点空气质量综合评价等级和应采取的相应的对策。评价结果能为铀矿井通风系统的设计和空气质量的安全评价提供参考。

The air anion is to have the negative charge air numerator , may make person be in high spirits , improve human body enginery, the air "vitamin" is called by people, may make person feel air "is stale " if being short of an anion , feel that the sense of suppression in the chest, gets nervous , dizziness , adyramia , availability and situation come down obviously.

空气负离子是带负电荷的空气分子，可使人精神振奋，提高人体机能，被人们称之为空气"维生素"，若缺乏负离子可使人感到空气"不新鲜"，感到胸闷、心慌、头晕、无力、工作效率和健康状况明显下降。

The article mostly discusses gas application burning excess air coefficient calculation methods, introduces different calculation formula application range, and giving examples in natural gas, liquefied petroleum gas and manufactured gas calculate its excess air coefficient on the same oxygen content of fuel gas, and the influences of excess air coefficient to air consumption and fuel gas production during burning process.

文章主要论述了燃气具燃烧过剩空气系数的计算方法，介绍了不同过剩空气系数计算公式的使用范围，并举例天然气、液化石油气和人工煤气三气种燃气具在测得烟气中相同氧含量时过剩空气系数的计算方法，以及过剩空气系数对燃气具在燃烧过程中消耗空气量和同时产生烟气量的影响。

Before the teaching activity, students' misconceptions of "air" concept mainly be, the student thinks the air isn't a kind of material, so the air isn't condensability, don't occupying space, and can't speaking out air current can be become common practice with form, its cause was that: the basic concept for air's quality was wrong and students always conducted incorrect judgment due to the ambiguity of literate meanings.

本研究的结果发现：学童在教学活动之前，有关「空气」的迷思概念主要是，学童认为空气不是一种物质，所以空气不可压缩，不占有空间，并无法说出空气流动可以形成风；其成因是：气体基本性质概念错误和常因字义不清而下判断错误。

Air resistance of counterflow closed circuit cooling tower is detailed tested, air flow regularity inside of the new tower is discussed and air flow characteristics through cooling bundle of tubes is analyzed.

在该实验台上详细测试了在封闭式冷却塔内空气与水逆向流动条件下，空气流经冷却盘管的阻力，探讨了封闭式冷却塔内空气的流动规律，分析了空气流过正三角排列管束的特性。

The results showed that behavior of the smog and TSP are in accordance to the formula of dynamics, changes of cresol mixed isomers' density conform with exponential function. With air disinfecting in indoor with smog, the killing percentage of Staphylococcus auras are up to 99.92% during 30 min, and that of natural bacteria is up to 99.66% during 120min, and the sm...

结果表明，烟雾及其有效成份在空气中按一定的规律沉降；并且在 30min作用时间内能够有效地杀灭空气中 99.92 %的金黄色葡萄球菌；在 12 0min内空气自然菌的平均杀灭率可达 99.66%，烟雾对室内空气环境具有一定的净化作用。

The depurator could purify air microorganisms at the workshop, with a purifying rate of 53.1％, but it did not reach the standards of clean air.

空气净化器虽然能够净化生产车间中的空气微生物，但其净化率为53.1％，净化后的空气未达到洁净空气的标准，因此还应同时采取其他相应净化措施。

According to people who had moustaches, inhaling the air component quantitative analysis and found that the air sucked into the presence of dozens of hazardous substances, including phenol, toluene, acetone, isoamyl asked diene, and other carcinogens,, Who had moustaches, who inhaled the air pollution index, is 4.2 times that of ordinary air.

据对留有胡子的人吸入的空气成分进行定量分析，发现吸进的空气中含有几十种有害物质，其中包括酚、甲苯、丙酮、异戊问二烯等多种致癌物，留有胡子的人吸入的空气污染指数，是普通空气的4.2倍。

In the technology of the mobile air conditioning room,the heat barrier is used to isolate work- ers from the hot environment and the cooling air is supplied for the mobile air-conditioning room by the turbine- typed air cooler whose cooling source and ventilating power come from cooling energy and potential energy stored in the water in constant temperature zone.

矿井移动空调室技术的实质是利用热幛将作业者与环境隔离，再用一种水轮机式空气冷却器向移动空调室内供冷。水轮机式空气冷却器的冷源和通风动力均来自矿井恒温带。通过实验得知：环境温度为32℃时，以1.6 m~3/h的速度供给水温为18℃的冷水启动空气冷却器10 min后，矿井移动空调室内干球温度可降至24℃；空气冷却器停止工作后30 min，矿井移动空调室内的空气温度仍可维持在28℃以下
