"CO2 detection could have evolved as a mechanism to recognize CO2-producing sources - for instance, to avoid fermenting foods," they wrote.
“二氧化碳探察可能演变为一种识别二氧化碳生产源的机能——例如，避免发酵食品。”他们写道。
Novomer prioritizes carbon sources based on purity and concentration of CO2.
Novomer公司更看重纯净度更高的碳来源以及集中于二氧化碳上。
Carbon capture and storage (CCS) is a process involving the capture of CO2 from power plants and other industrial sources for storage in sites such as depleted oil and gas fields.
管道附近500米以内的居民已被告知了该计划。CCS项目从发电厂和其他工厂捕获二氧化碳，再利用废弃的油、气田等场所把它储存起来。
Working noise sources are identified for a 5kw transverse flow CW CO2 Laser made by Laser Institute of Huazhong University of Science and Technology.
本文采用表面声强测量及其频谱分析方法对华中工学院激光研究所研制的5kw横流电激励连续CO_2激光器的噪声源进行识别。
Next to CO2, methane (CH4) is the second important contributor to global warming in the atmosphere and global atmospheric CH4 budget depends on both CH4 sources and sinks.
甲烷（CH4）是大气中仅次于CO2对全球变暖贡献第二大的温室气体，全球大气CH4的收支取决于CH4的源与汇。
Currently, Chongqing has more than 120 CO2 point emission sources.
