Achiral
非手性的
A molecule that is superimposable on its mirror image. In other words, it lacks chirality or "handedness." Many molecules important in materials science, like ethylene and benzene, are achiral.
与其镜像可以叠加的分子。换句话说，它缺乏手性或“旋向性”。许多在材料科学中很重要的分子，如乙烯和苯，都是非手性的。(yǔ qí jìng xiàng kě yǐ dié jiā de fēn zǐ. huàn jù huà shuō, tā quē fá shǒu xìng huò "xuán xiàng xìng". xǔ duō zài cái liào kē xué zhōng hěn zhòng yào de fēn zǐ, rú yǐ xī hé běn, dōu shì fēi shǒu xìng de.)
About the IPA
The International Phonetic Alphabet is a standardized system of symbols used to represent the sounds of spoken language.
It helps linguists, language learners, and educators accurately describe pronunciation across languages.
Example: the word "hello" in British English is transcribed as /həˈləʊ/ in IPA.
