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

在平衡状态交联键形成、溶解、再形成。

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.

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

交联键常也是由共价键形成，共价键是在原子共享电子的相互作用下形成，常需要化学反应才能使之形成或断裂。
