二氧化碳

In other experiments, Provine has proved that yawning has nothing to do with oxygen or carbon dioxide intake.

在其他的实验中，普罗万也证明打哈欠与氧气或者二氧化碳的吸入没有关系。

Due to the physical properties exhibit extremely rapid variations with the change of temperature near the pseudocritical point, the heat transfer performance of supercritical fluids are very different from that of conventional refrigerants.

二氧化碳跨临界循环放热过程处于超临界区，由于在准临界点附近CO2 的热物理参数变化非常剧烈，超临界区流体的换热有别于传统制冷剂，气体冷却器的换热优劣对系统性能影响较大。

The source,existing form and equilibrium of carbonic acid in natural water are presented in this article,which points out that alkalinity is determined by double indicator that indicates purply at the first terminal point,while at the second terminal point should use methyl red-bromocresol green mixed indicator.

介绍了天然水体中碳酸的来源、存在形式及平衡关系；指出用&双指示剂&法测定水中碱度的第一终点应显粉紫色，第二终点宜采用甲基红-溴甲酚绿混合指示剂；测定游离二氧化碳要用双样测定并严格控制滴定终点；各种碳酸的含量可与pH值、硬度的测定结果进行校核。

Experimental study on effect of acetic acid and carbonic acid on clay's geotechnical behaviors;2. The source,existing form and equilibrium of carbonic acid in natural water are presented in this article,which points out that alkalinity is determined by double indicator that indicates purply at the first terminal point,while at the second terminal point should use methyl red-bromocresol green mixed indicator.

Results:The weekly measurement shows that most of the air quaily are within the EPS suggested level except O3 and CO2 items. The CO2 conc.

结果：一周之量测结果显示，除臭氧和二氧化碳值外其他空气品质数据均未超过环保署建议值。

Yet the Gorgon consortium has scored green points with its plan to rebury the carbon dioxide it pumps up along with the field's gas.

然而戈尔工财团已经为重新处理气田中泵送的天然气和二氧化碳的计划得到了绿点。

Whether we imagine that states have agreed to a secondary rule under which there is a presumption of consent (rebuttable through the persistent objector doctrine) or we simply accept that consent is not necessary for a rule of CIL to bind a state makes little difference for present purposes .

关于推定同意的主张，新国家产生就要表示对既有普遍规则表示同意吗，那种认为同意这些次级规则是必要的和不可避免的主张无异于让人一生下来就必须得表示同意吸进氧气呼出二氧化碳一样荒谬。注133

Officials say it will help reduce air pollution by 600 tonnes of respirable particles and 160,000 tonnes of carbon dioxide a year.

政府表示，新铁路有助改善空气质素，每年可以减少空气中的微粒六百吨和二氧化碳十六万吨。

Respirable particulate matter ; radon ; carbon dioxide ; indoor air pollution

可吸入颗粒物；氡；二氧化碳；室内空气污染

A carbon dioxide laser can also be used to shrink the rhinophyma tissue.

1二氧化碳雷射也可以被用来缩小rhinophyma组织。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
