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.

由于它们的分子可以快交联键，因此这种材料是有弹性的，它们可以进行快地自我修复，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，这些共价键是在原子共享电子的相互作用下形成，通常需要化应才能使之形成或断裂。

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一种具有可释放交联的塑料。

(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。

The outer wall of a gram-positive bacteria cell consists of layers of peptidoglycan held together by crosslinks of proteins.

革兰氏阳性细菌细胞的外壁由层层肽聚糖通过蛋白质交联连接而成。

The crosslinks effectively weld  the polymer strands together This makes the rubber stiffer,   but also more brittle.

交联有效地将聚合物线焊接在一起，这使得橡胶更硬，但也更脆。

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

在这里，原子团会与原来的舞伴告别， 因为它们的交联断裂了。

If the penicillin is present while bacterial cells are dividing, the beta-lactam rings bind to the crosslinks while they are still under construction, preventing the completion of cell division.

若在细菌细胞分裂时存在青霉素，其β-内酰胺环会与正在构建中的交联结合，阻碍细胞分裂的完成。

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

那种固化会在这种塑料中的原子群之间形成交联。

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塑料不能简单地被熔化和重塑。

Then the groups pair up to crosslink with new partners.

然后这些原子团会重新配对， 与新的舞伴形成交联。
