用法:
Argon是一種稀有氣體,它的化學(xué)符號是Ar,原子序數(shù)為18。它是一種無色、無味、無毒的惰性氣體,存在于大氣中。它與其他稀有氣體一樣,具有很高的電離能力和低的化學(xué)反應(yīng)性。因此,在工業(yè)上,argon被廣泛用作保護性氣體、燈泡和電子管中的充填物以及焊接和切割過程中的惰性保護。
The atmosphere of Mars is composed mainly of carbon dioxide, with small amounts of nitrogen and argon.
例句2:
Argon is a common gas used in incandescent light bulbs.
例句3:
In welding, argon is often used as a shielding gas to protect the weld from atmospheric contamination.
在焊接中,通常使用氬作為保護性氣體來防止焊縫受到大氣污染。
Argon is also used in the production of titanium and other reactive elements to prevent oxidation during processing.
在生產(chǎn)鈦和其他活潑元素時也會使用氬來防止在加工過程中發(fā)生氧化。
Argon is an important gas in the semiconductor industry, used to create controlled atmospheres for processing silicon and other materials.
氬是半導(dǎo)體工業(yè)中重要的氣體,用于為加工硅和其他材料創(chuàng)建受控環(huán)境。
1. Noble gas (惰性氣體)
Noble gas is a term used to describe the group of elements that includes argon, helium, neon, krypton, xenon, and radon. These gases are characterized by their low chemical reactivity and high ionization energies.
惰性氣體是一個術(shù)語,用來描述包括氬、氦、氖、氪、氙和氡在內(nèi)的一組元素。這些氣體的特點是化學(xué)反應(yīng)性低,電離能高。
2. Inert gas (惰性氣體)
Inert gas is another term used to describe gases like argon that are unreactive under normal conditions. These gases are often used as protective atmospheres or in industrial processes where a lack of reactivity is desired.
惰性氣體是另一個術(shù)語,用來描述像氬這樣在正常條件下不會發(fā)生反應(yīng)的氣體。這些氣體通常被用作保護性大氣或在需要缺乏反應(yīng)性的工業(yè)過程中使用。
3. Helium (He) (He)
Helium is another noble gas that shares similar properties with argon. It is also unreactive and has a low boiling point, making it useful in cryogenics and as a coolant in nuclear reactors.
氦是另一種惰性氣體,與氬具有相似的性質(zhì)。它也是不活潑的,沸點低,因此在低溫學(xué)和作為核反應(yīng)堆冷卻劑中很有用。
Argon是一種重要的稀有氣體,在工業(yè)上被廣泛應(yīng)用。它具有高電離能力和低化學(xué)反應(yīng)性的特點,因此常被用作保護性氣體和惰性保護劑。它還可以用于燈泡、焊接、切割和半導(dǎo)體加工等領(lǐng)域。除了argon外,其他惰性氣體如氦和氪也具有類似的特點,并在不同領(lǐng)域發(fā)揮重要作用。
