CO和CO2经常被彼此弄错。两种气体都是无色和无味的。且都针对心血管系统。两种气体都能经过呼吸,皮肤和/或眼睛进入人体。两种气体导致的共同的症状包括头痛,头昏,惊厥和幻觉。 大多数的人很难判定它们的区别,不会意识到汽车会同时排放CO和CO2。在室内环境中,这类气体的积累会对暴露到它们的个人的健康和安全造成危险。

不同功能型的植物ANPP对大气CO2浓度升高的绝对变化量均为湿年大于正常年和干年;相对变化量则因具体植物功能型而异,灌木和亚灌木为干年大于正常年和湿年,一年生C3和C4草本均为湿年大于正常年和干年。因此,无论是生态系统水平还是植物功能型(或物种)水平,荒漠生态系统对未来大气CO2浓度升高的响应都将受降水格局的...
In order to demonstrate broadband spectroscopy with the EC-QCL, and to facilitate line selection for narrowband detection, DAS spectra over the mode-hop-free tuning range were recorded (no averaging) for two different samples: a mixture of the CO and CO2 standard gases (Fig. 2) and end-tida...

Interestingly, this NBO analysis of the Be–O bonds does not indicate a covalent interaction, but rather a lone pair on the O atom, which suggests a highly ionic interaction with the Be centre in line with the large electronegativity difference between these elements, and the calculated very ...
ED is an electrochemical membrane separation process where an electrically charged membrane and an electrical potential difference are used to separate ionic species in fruit juice from other uncharged components. The separation is based on the electrical charge of the particles. This technique is ...
