二氧化碳

For the reduced atmosphere in excessively many carbon dioxide, to our each person, although our strength is limited, but we try to change itself, for instance fosters economize on electricity the custom, countryside Returning farmland to forest, does not overcut the forest, profession few marine pollutions and so on marine transportation, every year participates in the afforestation, little uses even not to use the disposable convenience wooden chopsticks, saves the paper, does not trample the lawn and so on these actual motions to protect the good green plants, causes them when carries on the photosynthesis to absorb more carbon dioxide to help the Earth to slow down the greenhouse effect.

为减少大气中过多的二氧化碳，对我们每个人来说，虽然我们的力量有限，但我们试着改变自己，比如养成节约用电的习惯，农村的退耕还林，不乱砍滥伐森林，海运等行业较少海洋污染，每年参加植树造林，少用甚至不用一次性方便木筷，节约纸张，不践踏草坪等等这些实际的行动来保护好绿色植物，使他们在进行光合作用时吸收更多的二氧化碳来帮助地球减缓温室效应。

The relative concentrations of oxygen and carbon dioxide in the surrounding air determine the balance of photosynthesis and photorespiration and thus the efficiency of carbon fixation .

环境中氧气和二氧化碳的相对含量决定了光合合成和光呼吸的反应平衡和二氧化碳固定的效率。

The United States is the world's largest polluter, accounting for 25% of all carbon dioxide emissions, a major cause of global warming, despite its population of just 4% of the world's total.

美国是世界上最大的污染排放国，尽管它的人口只占全球人口的百分之四，但二氧化碳排放量占全球总排放量的25%，而二氧化碳排放是引起全球变暖的主要原因。

The result showed that CO2 and temperature treatment increased rice biomass, and CO2 fertilization effect had certain potence in rice grain yield increasing.

Too much CO2, and magnetite can't form, whereas the opposite is true for siderite.

如果大气中存在的二氧化碳太多，磁铁矿则无法形成；如果大气中存在的二氧化碳太少，菱铁矿则无法形成。

The concentration of carbon dioxide in natural seawater is sufficient for microalgal growth, but insufficient for high algal-density culture due to limitation of photosynthesis in the artificial medium. This study was adjusted the initial pH to 5.5, 6.5 and 7.5 by adding CO2 or HCl in 1L flask cultured stagnantly with continuous illumination.

对大多数藻类而言，在天然的水域中，二氧化碳的浓度是充足的，但在人工培养的情况下，藻类的密度很高，二氧化碳的供应往往不足，成为光合作用的限制因子，进而影响藻细胞的生长繁殖。

When confined within a suitable pressure vessel, carbon dioxide can exist in any of three states of matter depending on conditions of temperature and pressure.

如果将二氧化碳装入一个可承受适当压力的容器内，只要温度和压力达到一定条件，二氧化碳就会发生固态，液态和气态三种不同状态的变化。
