These crosslinks form and dissolve and form again in an equilibrium.

在平衡状态中这些交联键形成、溶解、再形成。

About 10 years ago, researchers in France developed plastics with releasable crosslinks.

大约 10 年前， 法国的研究人员开发了具有可释放交联的。

Their permanent crosslinks have meant these plastics can't just be melted and reshaped.

它们的永久交联意味着这些能仅仅被熔化和重。

That curing forms crosslinks among groups of atoms in this plastic.

这种固化会在这种的之间形成交联。

Here, groups of atoms say goodbye to their partners as their crosslinks break apart.

在这里，在它们的交联断裂时向它们的伙伴说再见。

Then the groups pair up to crosslink with new partners.

然后这些小组配对以与新合作伙伴交联。

Because their molecules can shift their crosslinks around on the fly, the materials are stretchy, can repair themselves quickly, can dissipate excess energy, and are usually soft.

由于它们的分可以快速改变交联键，因此这种材是有弹性的，它们可以进行快速地自我修复，消耗多余的能量，它们通常是比较柔软的。

Those crosslinks are generally also formed from covalent bonds, which are interactions where atoms share electrons and generally require a chemical reaction to make or break.

这些交联键通常也是由共价键形成，这些共价键是在共享电的相互作用下形成，通常需要化反应才能使之形成或断裂。

(Applause) So what we had to do was figure out a way to put a sensor, connected to this crosslinks of the stent that could record that brain activity.

（掌声）所以我们必须想办法放置一个传感器，连接到支架的这个交联点上可以记录大脑的活动。
