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

平衡状态中些交联键形成、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塑料。

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

们的永久交联意味着些塑料不能仅仅被熔化和重塑。

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

种固化会种塑料的原子团之间形成交联。

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

，原子团们的交联断裂时向们的伙伴说再见。

Then the groups pair up to crosslink with new partners.

然后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.

由于们的分子可以快速改变交联键，因此种材料是有弹性的，们可以进行快速地自我修复，消耗多余的能量，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.

些交联键通常也是由共价键形成，些共价键是原子共享电子的相互作用下形成，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，连接到支架的个交联点上可以记录大脑的活动。
