Chemical bond
化学键
The attractive force that holds atoms together in a molecule. Understanding different types of chemical bonds (covalent, ionic, metallic) is crucial in materials science to predict and explain the properties of materials.
将原子结合在一起形成分子的吸引力。了解不同类型的化学键（共价键、离子键、金属键）对于材料科学中的预测和解释材料的性质至关重要。(jiāng yuán zǐ jié hé zài yī qǐ xíng chéng fēn zǐ de xī yǐn lì. liǎo jiě bù tóng lèi xíng de huà xué jiàn (gòng jià jiàn, lí zǐ jiàn, jīn shǔ jiàn) duì yú cái liào kē xué zhōng de yù cè hé jiě shì cái liào de xìng zhì zhì guān zhòng yào.)
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.
