Polymer
Mandarin:
聚合物 (jù hé wù)
聚合物 (jù hé wù)
Explanation in English Language (EN):
A polymer is a large molecule (macromolecule) composed of many repeating structural units called monomers. These monomers are linked together by covalent bonds to form long chains or networks. Polymers can be natural, such as proteins and DNA, or synthetic, such as polyethylene and nylon. Polymers exhibit a wide range of properties, including strength, flexibility, elasticity, and resistance to chemicals, making them essential materials in various applications.

Explanation in Mandarin (ZH):
聚合物是一种大分子（高分子），由许多称为单体的重复结构单元组成。这些单体通过共价键连接在一起，形成长链或网络。聚合物可以是天然的，例如蛋白质和 DNA，也可以是合成的，例如聚乙烯和尼龙。聚合物表现出广泛的性能，包括强度、柔韧性、弹性和耐化学性，使其成为各种应用中的重要材料。
