But the researchers were able to make rubber self-heal by replacing the sulfur in the rubber with a pair of charged molecules, or ions, called butyl imidazolium and bromide.

但是，研究人员可以通过成对的带分子或离子替换其中的硫磺使这橡胶自行修复，叫做丁基咪唑鎓盐和溴化物。

Butyl imidazolium has a positive charge, and it's always accompanied by a negatively charged bromide, just like the ions of sodium and chloride that you find in table salt.

丁基咪唑鎓盐拥有，总是伴随着一个负的溴化物，就像盐粒中的钠离子和氯离子。
