['ˈɑːɡɑːn]
n. 氩;氩气;[化] 稀有气体
用法:
Argon是一种稀有气体,它的化学符号是Ar,原子序数为18。它是一种无色、无味、无毒的惰性气体,存在于大气中。它与其他稀有气体一样,具有很高的电离能力和低的化学反应性。因此,在工业上,argon被广泛用作保护性气体、灯泡和电子管中的充填物以及焊接和切割过程中的惰性保护。
例句1:
The atmosphere of Mars is composed mainly of carbon dioxide, with small amounts of nitrogen and argon.
火星大气主要由二氧化碳组成,含少量氮和氩。
例句2:
Argon is a common gas used in incandescent light bulbs.
氩是灯泡中常用的一种气体。
例句3:
In welding, argon is often used as a shielding gas to protect the weld from atmospheric contamination.
在焊接中,通常使用氩作为保护性气体来防止焊缝受到大气污染。
例句4:
Argon is also used in the production of titanium and other reactive elements to prevent oxidation during processing.
在生产钛和其他活泼元素时也会使用氩来防止在加工过程中发生氧化。
例句5:
Argon is an important gas in the semiconductor industry, used to create controlled atmospheres for processing silicon and other materials.
氩是半导体工业中重要的气体,用于为加工硅和其他材料创建受控环境。
同义词及用法:
1. Noble gas (惰性气体)
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.
惰性气体是一个术语,用来描述包括氩、氦、氖、氪、氙和氡在内的一组元素。这些气体的特点是化学反应性低,电离能高。
2. Inert gas (惰性气体)
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.
惰性气体是另一个术语,用来描述像氩这样在正常条件下不会发生反应的气体。这些气体通常被用作保护性大气或在需要缺乏反应性的工业过程中使用。
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.
氦是另一种惰性气体,与氩具有相似的性质。它也是不活泼的,沸点低,因此在低温学和作为核反应堆冷却剂中很有用。
编辑总结:
Argon是一种重要的稀有气体,在工业上被广泛应用。它具有高电离能力和低化学反应性的特点,因此常被用作保护性气体和惰性保护剂。它还可以用于灯泡、焊接、切割和半导体加工等领域。除了argon外,其他惰性气体如氦和氪也具有类似的特点,并在不同领域发挥重要作用。
