单体
monomers is the plural of monomer.
a simple compound whose molecules can join together to form polymers
- 1.
A relatively small molecule which can be covalently bonded to other monomers to form a polymer or oligomer.
一种相对较小的分子,能与其他单体通过共价键结合形成聚合物或低聚物。

In use
Ethylene is a simple monomer that can link into long plastic chains.
The polymer is made from thousands of monomers joined end to end.
Each monomer contains a reactive group that helps it bond with the next one.
a monomer of [chemical compound]
用 of 引出单体聚合后形成的聚合物或其他物质。
Ethylene is a monomer of polyethylene.
乙烯是聚乙烯的一种单体。
monomers polymerize to form [polymer]
monomer 通常用复数，表示多个单体共同参与聚合。

这些单体聚合形成一种坚固的塑料。
[adjective] monomer
形容词可说明单体类型，如 vinyl、acrylic 等。
This vinyl monomer is highly reactive.
这种乙烯基单体反应性很强。
a monomer used in [process]
过去分词短语作后置定语修饰 monomer。
It is a monomer used in making synthetic rubber.
它是制造合成橡胶所用的单体。
Common mistakes
The polymer chain is made up of thousands of monomer.The polymer chain is made up of thousands of monomers.
单体（monomer）是可数名词，在“thousands of”等复数数量词后必须用复数形式 monomers。汉语名词没有复数变化，所以容易漏掉词尾的 -s。
Each monomer have a reactive group at one end.Each monomer has a reactive group at one end.
each 作主语或修饰主语时，谓语动词要用单数形式（has）。monomer 是单数可数名词，与 each 搭配时强调单个个体，不能用 have。
The small molecules that join together are called polymers.The small molecules that join together are called monomers.
聚合物（polymer）由单体（monomer）聚合而成。这里指的是参与聚合的小分子，应该用 monomer（单体），而不是 polymer（聚合物）。两个词在中文里分别对应“单体”和“聚合物”，容易混淆。

Learner notes
Memory Tip
mono-像“一”，-mer像“部分”：单体就是一个个能串联成聚合物的单元。
Context & Register
语域：formal 常见场景：高分子化学教材、化学论文、材料科学文献 monomer 多用于化学、高分子材料等专业语境，属于正式/学术用词，日常口语中很少出现。
Pronunciation & Spelling
In monomer the ending -mer is pronounced /mə/. Polymer, isomer, consumer, former, and customer all end with the same /mə/ sound and the same -mer spelling. Summer also ends with /mə/ but is spelled -mmer, so it looks similar but is not a true -mer match. None of these words rhyme with monomer because the stressed syllable and following sounds differ.
