?一:膦的是什么意思(中英文)解釋的意思
膦(phosphine)是一種無機化合物,由磷原子和氫原子組成。它的化學(xué)式為PH3,是一種無色、有毒氣體。在常溫下,膦具有刺激性的臭雞蛋味道。它主要用于制造殺蟲劑和金屬表面處理劑。
Phosphine is an inorganic compound composed of phosphorus and hydrogen atoms. Its chemical formula is PH3, and it is a colorless and toxic gas. At room temperature, phosphine has a pungent smell similar to rotten eggs. It is mainly used in the production of insecticides and metal surface treatment agents.
膦的發(fā)音為/f?sfi?n/,其中/f?s/為重音。
The pronunciation of phosphine is /f?sfi?n/, with the stress on /f?s/.
膦主要用于制造殺蟲劑和金屬表面處理劑。它可以通過與其他化合物反應(yīng)來制備不同類型的殺蟲劑,如氟磷酸酯類殺蟲劑。此外,膦也可以作為金屬表面的清潔和防銹劑使用。
Phosphine is mainly used in the production of insecticides and metal surface treatment agents. It can be used to prepare different types of insecticides, such as organophosphorus insecticides, by reacting with other compounds. In addition, phosphine can also be used as a cleaning and anti-corrosion agent for metal surfaces.
1. The chemist synthesized a new type of insecticide by reacting phosphine with fluorophosphoric acid.(化學(xué)家通過膦與氟磷酸反應(yīng)合成了一種新型殺蟲劑。)
2. Phosphine gas is highly toxic and should be handled with caution.(膦氣體具有高毒性,應(yīng)當小心處理。)
3. The metal surface treatment agent contains a small amount of phosphine to prevent rusting.(金屬表面處理劑中含有少量的膦,以防止生銹。)
4. The smell of rotten eggs is often associated with the presence of phosphine gas in the air.(空氣中存在膦氣體時,往往會有臭雞蛋的味道。)
5. Many countries have banned the use of phosphine due to its harmful effects on human health and the environment.(許多已經(jīng)使用膦,因為它對人類健康和環(huán)境有害。)
膦的同義詞包括磷化氫、三氫化磷等。它們都是指同一種化合物,只是命名方式不同。除了用作殺蟲劑和金屬表面處理劑外,膦也可以用作半導(dǎo)體材料的制備。
Some synonyms of phosphine include hydrogen phosphide and trihydrogen phosphide. They all refer to the same compound, but with different naming conventions. In addition to being used as insecticides and metal surface treatment agents, phosphine can also be used in the production of semiconductor materials.
膦是一種無色、有毒氣體,主要用于制造殺蟲劑和金屬表面處理劑。它的發(fā)音為/f?sfi?n/,可以通過與其他化合物反應(yīng)來制備不同類型的殺蟲劑。除了在農(nóng)業(yè)和工業(yè)領(lǐng)域的應(yīng)用外,膦也可以用作半導(dǎo)體材料的制備。由于其對人類健康和環(huán)境具有危害性,許多已經(jīng)使用膦。因此,在使用膦時需要小心處理,并且要注意防止其對環(huán)境造成污染。
