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分子或离子替换其中硫磺使这橡胶自行修复，叫做丁基咪唑鎓盐物。

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.

丁基咪唑鎓盐拥有正荷，总是伴随着一个负荷物，就像盐粒中钠离子氯离子。
