- couple
Couple emphasizes physically linking or connecting two things (often mechanically), or figuratively combining two elements; it sounds more formal or technical than pair in this sense.
couple强调把两个物体物理连接或衔接起来（常用于机械连接），也可比喻性地把两种因素结合在一起；这个意义比pair更正式、更偏技术性。

- pair 本词
Pair emphasizes matching two similar or complementary things, or grouping two people together to form a set; it is the everyday, common choice for socks, shoes or partners.
pair强调把两个相似或互补的东西搭配在一起，或把两个人组成一组；这是日常最常用的说法，比如配对袜子、鞋子或搭档。
The teacher paired each student with a partner for the science project.
老师把每个学生和一个搭档配对，一起完成科学项目。
Couple and pair both mean joining two things together. Couple stresses a physical or abstract connection and sounds formal; pair stresses matching two similar or complementary things and is more everyday. This does not compare their noun uses, such as 'a couple of friends'.
这两个词在“把两者结合在一起”这个意义上接近，但couple更强调物理连接或抽象结合，语气较正式；pair更强调把相似或互补的两者搭配成一组，日常更常用。这里不比较couple作名词表示“一对，几个”（a couple of friends）以及pair作名词表示“一双，一对”（a pair of shoes）的用法。
