在英汉翻译和化学术语使用中,monomer与polymer的辨析需注意以下要点:
一、构词与词源差异
1. monomer(单体)
- 希腊语词根"mono-"(单一)+"meros"(部分)
- 汉语对应"单体",强调独立存在的基本单元
- 例:Ethylene is the monomer for polyethylene(乙烯是聚乙烯的单体)
2. polymer(聚合物)
- 希腊语词根"poly-"(多)+"meros"(部分)
- 汉语对应"聚合物/高分子",强调重复单元的组合
- 例:PVC is a polymer widely used in construction(P ...(以上内容有节略,please sign in for more)
A long or larger chemically bonding together many identical or similar small molecules called monomers. A polymer is formed by polymerization, the joining of many monomer molecules.
A material consisting of such polymer molecules.
A relatively small molecule which can be covalently bonded to other monomers to form a polymer.
Any one of two or more substances related to each other by polymerism; specifically, a substance produced from another substance by chemical polymerization.
The basic conceptual building unit of a polymer; a molecule of low molecular weight which may combine with other molecules to form a molecule in a chain or branched form having high molecular weight; as, amino acids are the monomer units which are combined to form proteins; vinylic plastics are formed from monomers having a vinyl group.
