易混淆词
propellant
EN: 'Propellant' is the substance that provides propulsion (e.g., fuel); 'propulsion' is the act or force of propelling.
zh: 'Propellant'（推进剂）是提供推力的物质（例如燃料）；'propulsion'（推进）是推动的行为或力量。
impulsion
EN: 'Impulsion' refers to a sudden urge or driving force, often psychological; 'propulsion' is more physical/mechanical.
zh: 'Impulsion'指的是一种突然的冲动或驱动力，通常是心理层面的；而'propulsion'则更偏向物理/机械层面。
拼写提示
EN: Note that 'propel' has a single 'l', but derivatives like 'propellant' double the 'l' before a vowel suffix. The related word 'propeller' also doubles the 'l'.
zh: 请注意，'propel'只有一个'l'，但像'propellant'这样的派生词在元音后缀前会将'l'双写。相关的词'propeller'也将'l'双写。
