一:氩是什么意思(中英文)解释的意思
氩是一种化学元素,原子序数为18,符号为Ar,属于惰性气体。它是一种无色、无味、无毒的气体,在自然界中以稀有气体的形式存在。氩具有较高的化学稳定性和热稳定性,不易与其他元素发生反应。
Argon (Ar) is a chemical element with atomic number 18 and symbol Ar. It belongs to the group of noble gases and is a colorless, odorless, and non-toxic gas. It exists in nature as a rare gas. Argon has high chemical stability and thermal stability, making it difficult to react with other elements.

氩主要用于保护焊接、电弧切割和灯泡充填等工业领域。它也被用作混合气体中的惰性成分,如氩-二氧化碳混合物常用于焊接不锈钢。此外,氩还可以作为充填物用于保鲜食品和保护电子元件。
Argon is mainly used in industrial fields such as welding protection, arc cutting, and light bulb filling. It is also used as an inert component in gas mixtures, such as argon-carbon dioxide mixture commonly used for welding stainless steel. In addition, argon can be used as a filler for preserving food and protecting electronic components.
1. 氩气的化学性质稳定,可以用来保护焊接过程中的金属。
The chemical stability of argon gas makes it suitable for protecting metals during welding.
2. 由于氩是一种惰性气体,它不会与其他元素发生反应。
As argon is a noble gas, it does not react with other elements.
3. 我们需要用氩来填充这个灯泡,以保证灯丝不会被氧化。
We need to fill this light bulb with argon to prevent the filament from oxidizing.
4. 氩-二氧化碳混合物在焊接不锈钢时可以提高焊缝的质量。
The quality of welds can be improved by using an argon-carbon dioxide mixture when welding stainless steel.
5. 这种保鲜袋内充满了氩,可以延长食品的保鲜期限。
This preservation bag is filled with argon, which can extend the shelf life of food.
惰性气体(inert gas)是指在常温常压下具有稳定的电子结构,不易与其他元素发生反应的一类气体。除了氩外,还包括氦、氖、氪、氙和铑等。
Inert gas is a type of gas with a stable electronic structure at normal temperature and pressure, which is not easily reactive with other elements. In addition to argon, it also includes helium, neon, krypton, xenon, and radon.
氩是一种惰性气体,具有高化学稳定性和热稳定性。它在工业领域有着广泛的应用,如保护焊接、电弧切割和灯泡充填等。同时,氩也可以作为保鲜食品和保护电子元件的充填物。除了氩外,还有其他惰性气体可以发挥类似的作用。熟悉氩的用法和特性可以帮助我们更好地利用这种重要的化学元素。
