alkane的音标是["ælkəneɪ],基本翻译是“烷”。
速记技巧:可以记为“烷”就是“烷烃”的意思。
Alkanes是碳氢化合物的一种,其名称来源于希腊语“αλκάνη”,意为“难以征服的”。它们的化学性质稳定,不易发生化学反应。
变化形式:在烷烃中,碳原子之间通过单键连接,每个碳原子可以连接多个氢原子,形成长链。随着碳原子数量的增加,烷烃的分子量逐渐增加,其物理性质也会发生变化。

英文小作文:
Alkanes are a type of hydrocarbon that are long-chain molecules with a straight or branched structure. They are commonly found in natural gas and petroleum and are used in various applications, including fuel for vehicles and other devices, heating and cooking purposes, and as a component in fuel supply systems.
One of the unique characteristics of alkanes is their high flammability, which makes them a dangerous but also useful substance in certain contexts. However, their purity and stability are crucial for precise measurement and analysis, as well as for ensuring safe and reliable use. In addition, the mixture of alkanes can be used for various purposes, including heating and cooking, and the storage of alkanes is also an important aspect of fuel supply systems.
