But Sauvage and his team used copper ions to coax molecules into interlocking like links in a chain, which they call a catenane.

但是索维奇及他的团队使用铜离子诱导分子如同链环般相互扣住，这就是他们所说的链。

Normally, different molecules are connected by covalent chemical bonds between their atoms. But Sauvage and his team used copper ions to coax molecules into interlocking like links in a chain, which they call a catenane.

通常，不同的分子通过其原子之间的共价化学键连接。但是 Sauvage 和他的团队使用铜离子诱使分子像链条中的链接一样相互连接，他们称之为链烷。
