Most of the molecular characteristic absorption is very weak, and the absorption line width is very narrow that can't be measured by traditional methods.

TDLAS系统的关键是利用激光二极管有很高光谱分辨率和可调谐性的特点，可以对特定分子在特定光谱范围内的一条振转线的光谱吸收进行测量而反演吸收气体的浓度，而且能够把待测分子与背景的干扰区分开来。

Typical electrical code requirements include classification for instrument s and/or limiting the surface temperature of heated resistance elements to a specified fraction of the autoignition temperature for the flammable gas.

典型的电力法规要求包括器具的分类，和/或把热电阻元件的表面温度限制在易燃气体的自燃温度的一个指定的分数。

Wang's experiment used a very different approach, depending on the way that a light beam is changed by passing through a specially prepared tube of caesium gas.

王的实验采用了相对不同于Nimtz的方法，他测量的是光束在通过一个特别预备的充满铯气体的管子时候的变化。

World's Craziest Geoengineering Scheme A manmade volcano erupting continuously to shade the Earth until greenhouse gas levels in the atmosphere are brought down. Thousands of mirrors boosted into geosynchronous orbit to block sunlight. Crewless ships wander the oceans spewing saltwater into the air to increase cloud cover. These are just a few of the proposals from scientists to manipulate, or geoengineer, the planet to stave off global warming.

大家网翻译交流论坛 http：//club.topsage.com/forum-110-1.html 世界上最疯狂的地球工程方案利用人造火山不断地喷发，以便使地球处于阴凉之下直到大气中温室气体的水平下降；把成千上万的反射镜安放于地球同步轨道上，以期拦住太阳光；让游弋于海洋中的无人轮船向空气中喷洒盐水，以便增加云层的覆盖……为了控制全球变暖，科学家们提出了不少方案来控制地球，或者说是进行地球工程。

It is also applicable to measure micro-pressure and negative pressure of neutral gases without danger of explosion in boiler draft equipments, which cause no erosive attack on copper alloy. In addition, it has a function of dual two-position adjustment, so as to realize position

YEJ-121型矩形接点膜盒压力表是适用于锅炉通风设备对铜合金不起腐蚀作用的和中性、无爆炸危险的气体的微压和负压进行测量并具有双二位调节的作用，以实现位式调节或超限报警作用。

There are four Broad classes of turbine: water, steam, wind, and gas.

主要的涡轮机有四种：水力、蒸汽的、风力的和气体的。

The discharging current of the accelerator is measured with the Rogowski Coil,the discharging characteristic of the fast electromagnetic valve and the Ar-gaspressure in the coaxial plasma gun are measured with small piezo-electricpressure probes, and the velocity of the plasma in the coaxial plasma gun ismeasured with magnetic pickup coils.

使用压力传感器研究了所研制脉冲电磁阀门的时间特性，以及等离子体碎片加速器同轴枪内中性气体的压力分布；设计罗科夫斯基线圈并测量了本装置的放电电流；设计磁探圈并测量了同轴枪内等离子体的平均速度。

The numerical simulation of the water infiltration in dry sands and fly ash in two-dimensional shows that the influences of pore gas flowing on the water infiltration process are different for soil with different air permeability, which can not be ignored when air permeability of soil is low.

数值结果表明，对导气率不同的土类，孔隙气体的排出过程对孔隙水入渗运动有不同的影响，对导气率低的土类影响很大，且不可忽略。

Clausius had recently published two articles using the mathematics of probabilities to express the velocities of molecules in gas, and this stimulated Maxwell to write about gas molecules having a range of velocities, known today as the Maxwell
