And we can even create more elaborate structures if we use unsymmetrical molecules, where one polymer chain is significantly shorter than the other.

如果我们使用不对称分子，我们甚至可以创造出更精细的结构，那种情况下其中一个聚合物链明显短于另一个。

Polyethylene can actually be converted into a thermoset polymer by introducing cross-links, basically molecular bridges between those polymer chains.

聚乙烯实际上可以通过引入交联转化为热固性聚合物，基本上是这些聚合物链之间的分子桥。

One type of self-assemble material -- it's called a block co-polymer -- consists of two polymer chains just a few tens of nanometers in length.

有一种自组装材料叫做嵌段共聚物，由两条只有几十纳米长的聚合物链组成。

All DNA is made up of four distinct molecules known as bases, strung together in combinations to form long polymer chains.

所有 DNA 均由四种不同的分子（称为碱基）组成，它们组合在一起形成长聚合物链。

And the size of this cylinder and the distance between the cylinders, the periodicity, is again determined by how long we make the polymer chains and the level of built-in frustration.

这个圆柱体的大小和圆柱体之间的距离，周期性，也是由我们制造聚合物链的时间长短和内部障碍程度决定的。

And the width of the fingerprint lines and the distance between them is determined by the lengths of our polymer chains but also the level of built-in frustration in the system.

指纹线的宽度和它们之间的距离是由我们的聚合物链的长度决定的，同时也由系统内嵌的挫折程度决定。
