二氧化碳

We can pump excess CO2 from manufacturing processes or whatever into the ponds, and the algae converts it because it needs it for photosynthesizing, said Baltensperger.

他说：&我们可以将生产过程中产生的二氧化碳抽到水塘里，水藻可以把它转化，因为水藻需要二氧化碳进行光合作用。&

The reason is that green plants under sunlight undergo photosynthesis while respiring, hence they consume the carbon dioxide in air and release oxygen in return.

由於绿色植物在阳光下，除了进行呼吸作用外，亦同时进行光合作用，消耗空气中的二氧化碳，同时放出氧气，这便有助保持空气中二氧化碳和氧气含量的相对恒定。

That sequesters the CO2, that disposes of the CO2 in geological time, and also gives an economic benefit in terms of enhanced oil recovery.

这个方法隔离了二氧化碳，让二氧化碳在漫长的地质时间中被缓慢地处理掉，同时也增加了石油的产量，提高了经济利益。

China and the United States are the world's top two emitters of carbon dioxide, from burning coal and oil.

中国和美国是世界上两个最大的二氧化碳排放国，烧煤和用油造成了二氧化碳的排放。

Some groups that support burning oil and coal want to increase the amount of carbon dioxide in the atmosphere.

有一些人支持燃烧煤炭从而来增长空气中二氧化碳的含量，所以他们反对国际上为控制二氧化碳而做出的努力。

Plants need carbon dioxide and light to perform their photosynthesis process, so your tank is going to need to be well lit at least part of the day and may require the addition of an artificial carbon dioxide producer.

植物需要二氧化碳和轻履行其光合作用的过程，所以您的油箱将需要有良好的点燃至少有一部分每天可能需要增加一个人工二氧化碳生产者。

For instance, the rate of photosynthesis rises with increasing light intensity as long as there is sufficient carbon dioxide available, but at high light intensities carbon dioxide may become the limiting factor instead.

例如只要有足够的二氧化碳可利用，光照强度升高时光合作用的速率就会提高，但当光照强度过高时二氧化碳反而可能成为限制因子。

The apparatus and processes of the present invention are designed to address concerns with carbon dioxide impurities, particularly with carbon dioxide supplied at the point of use in the manufacturers' process.

本发明的设备和方法是设计用来解决二氧化碳杂质，特别是在制造过程的使用阶段提供的二氧化碳相关的问题。

This is typically done by exchanging the ethanol for liquid acetone, allowing a better miscibility gradient, and then onto liquid carbon dioxide and then bringing the carbon dioxide above its critical point.

这是典型的交流所做的乙醇液体丙酮，允许一个更好的相容性梯度，然后到液体二氧化碳，然后将其二氧化碳的临界点以上。

Surface tension effects on condensate retention angle and condensation heat transfer coefficient of carbon dioxide were studied.

综述了水平低翅片管外凝结传热的基本模型，阐述了二氧化碳制冷剂的物性特点，讨论了表面张力与凝液滞留角及二氧化碳管外凝结换热系数的关系，分析了翅片密度、环形翅片管尺寸对翅片效率、滞留角、凝结换热系数以及传热增强比的影响，优化了外翅片管的齿高与齿距，并求得相应的强化传热增强比。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
