covalent bond的音標(biāo)是[?kɑ?v?l?nt ?b??nd]，基本翻譯是“共價(jià)鍵”，速記技巧是“共同價(jià)值”+“連接”。共價(jià)鍵是指原子間通過共用電子對(duì)形成的化學(xué)鍵。

Covalent Bond：

Covalent這個(gè)詞來源于拉丁語，意思是“共享的，共同的”。Bond這個(gè)詞在英語中通常用來表示連接或結(jié)合，所以covalent bond可以理解為共享連接。

變化形式：詞形不變，但通常在化學(xué)領(lǐng)域中，我們更常使用covalent bond這個(gè)詞。

相關(guān)單詞：

1. Covalent Dimer 二聚體 - 兩個(gè)分子通過共享電子形成的鍵合雙分子。

2. Covalent Triplet 三聚體 - 三個(gè)分子通過共享電子形成的鍵合三分子。

3. Covalent Polymer 共價(jià)聚合物 - 由多個(gè)分子通過共享電子形成的鍵合聚合物。

4. Covalent Cross-Linking 共價(jià)交聯(lián) - 通過共價(jià)鍵將分子連接在一起，使材料更加堅(jiān)固和穩(wěn)定。

Covalent Bonds: The Foundation of Chemical Stability and Polymer Properties

Covalent bonds are essential for the stability of chemical compounds and the mechanical properties of polymers. These strong and stable bonds are formed between atoms through the sharing or transfer of electrons, resulting in a highly ordered molecular structure. Covalent bonding plays a crucial role in determining the chemical and physical properties of materials, making it a key aspect of materials science and chemistry research. Understanding covalent bonding mechanisms and strengths can help us develop new materials with enhanced properties and applications. Furthermore, covalent polymers have attracted much attention in the field of advanced materials due to their unique mechanical, electrical, and chemical properties, making them promising candidates for various applications in the field of electronics, optics, and biomedicine. Therefore, covalent bonds hold great promise for future advances in science and technology.
