I also read about using metal oxide.

我还读了一些有关使用金属物的书。

Even as we humans count on forests to soak up a good share of the carbon dioxide we produce, we are threatening their ability to do so.

即使我们指望森林吸收很大一部分人类生产的二，其吸收能力正在遭受人类的威胁。

For a start, all animals, such as cows, pigs and sheep, always gas limed methane, which is the second most common green house gas after carbon dioxide.

首先，所有动物如牛、猪、羊都会排出甲烷气体，它是排在二之后的第二大常见的温室效应气体。

Several companies already make materials that strip carbon dioxide from the air.

多家公司已经制造出可从空气中吸除二的材料。

Will the U.S. have a law limiting carbon dioxide?

美国会出台限制二排放的法律？

Heating this chemical compound drives off carbon dioxide gas leaving calcium oxide.

加热这种合物会驱除二气体，留下。

Rocks like plagioclase and olivine that contain calcium and magnesium naturally absorb carbon dioxide to become limestone or dolomite.

比如含有和镁的斜长石和橄榄石可以自然吸收二转变成石灰岩和白云石。

But this chemical seems to counteract an enzyme called quinol-oxidase.

但这种合物似乎可以抑制苯二酚酶。

Carbon dioxide and sulphuric acid clouds is what makes up my atmosphere, and for this, I am very proud.

二和硫酸云是我大气的组成成分，我为此非常骄傲。

Again, I can't stress the dangers of carbon monoxide poisoning which is absolutely avoidable.

再说一遍，我一再强调一中毒的危险性，这是绝对可以避免的。

That's where the liquid is depressurised and so it reverts to a gas. Then the oil and grease are separated out and sent to the waste system.

在那里，液体二会被减压，然后变成气体。而那些油脂会被分离出来送到废物系统中去。

When we replace meals with a protein bar or drink, we also risk missing out on the rich sources of antioxidants, vitamins and many other benefits of real food.

当我们用蛋白棒或蛋白饮料代替正餐时，我们也有可能错过真正食物中丰富的抗剂、维生素和许多其他有益物质。

As the trees burn, they release carbon dioxide.

树木燃烧时释出二。

Best of all, it does not emit harmful carbon dioxide into the atmosphere.

最好的一点是，Kayoola不会向大气释放有危害的二。

Many drugs exist, like benzoyl peroxide, which kills specific acne-causing bacteria, salicylic acid, which helps to remove dead skin blockages, retinoids, which reduce sebum production, and a variety of others —though some drugs can have severe side effects.

目前有许多药物，像是过苯甲酰，那能消灭特定的致痘细菌，水杨酸，有助去除死皮造成的阻塞，维他命 A 酸，那能减少皮脂生成，还有其它许多药物－－不过有些药物可能会造成严重副作用。

The Sport Collection has an Ion exchange cover glass and an anodized aluminum case that is 60% stronger than standard alloys, and yet it's incredibly light and durable.

Sport系列，搭配离子交换玻璃表面，以及阳极铝金属表壳，比普通合金坚固60%，却极为轻盈、耐用。

But it gets even better, as the oxygen of the air bubble runs out, new oxygen diffuses into the bubble from the water around, it while the carbon dioxide diffuses outwards into the water.

但不只如此，外膜中的气用完时，新的气从周围的水扩散到膜内，而二向外扩散到水中。

Copper ions do this by interacting with oxygen and changing the oxygen molecules. As a result, the virus cells cannot mutate.

铜离子能与合并改变分子结构，这样病毒细胞就无法突变。

The poster is coated with titanium dioxide and can consume the nitrogen oxide exhaust of about 20 cars per day.

这面广告牌的表面涂有二钛，可以吸收相当于20辆汽车一天排放的一氮量。

Mineral products that contain zinc oxide and titanium dioxide will still be allowed.

含有锌和二钛的矿产品仍然是允许的。
