a can opener 的音标是[ə] [kæn] [ˈəʊpənər] ，含义是开罐器，分别的发音是[kæn] [əʊpənər]，分别的用法如下：n. 分别；分开的时刻；区别；不同；分别的事物；各自的东西；各自的情况；adj. 分别的；各自的；不同的；各自地；v. 分开(separate的现在分词)；使分离。可以这么记：a/can/opener分别由/æ/，/k/，和/ən/，/əʊ/，/pənər/拼写而成，可以联想到开罐头的东西，所以叫开罐器。
a can opener涉及到物理现象：力的作用，杠杆原理。在用开罐头器开罐头时，我们利用了力的作用效果之一：改变物体的形状，使金属片插到罐头盖子上，利用杠杆原理，省力。
