Evolution has provided a goodly range of these in the form of enzymes, which are large, complicated and sometimes temperamental protein molecules, but which have the advantage that they can create pure versions of what are known as optical isomers.

进以酶的形式提供了大量的这类物质，这些酶是大型的、复杂的、有时还会变无常的蛋白质分子，但它们的优点是可以产为光异构体的纯净版本。

Also, ketamine itself, S-ketamine is an isomer of ketamine that's been patented for depression.

此外，氯胺酮本身，S-氯胺酮是氯胺酮的一种异构体，已专利用于治疗抑郁症。

And you're quite right, it can be heterogeneous.

是对的，它可以是异构的。

But now, We have a vast array of heterogeneous technologies with different capabilities.

但现在，我们拥有大量不能力的异构技术。

If all of the things attached to those carbons are the same, it doesn't matter, but if the parts are different, it's possible to have two totally different isomers of the same compound.

如果连接在这些碳原子上的所有基团都相，则无影响；但如果这些基团不，则可能形成两种完全不的一合物的异构体。

You also learned a little bit about cis-trans isomerism and learned a few important reactions of alkenes and alkynes such as hydrogenation, halogenation, and polymerization.

还了解了一点关于顺反异构体的知识，并习了一些烯烃和炔烃的重要反应，如氢、卤和聚合。

What do you feel like the missing layer of tooling is for this generation of, okay, now we're moving into the heterogeneous world?

觉得对于这一代来说，现在我们正进入异构计算的世界，还缺少哪一层工具呢？

They might be deployed against fuel and ammunition stores too A week-long demonstration of HCUS is planned for later this year.

它们也可能部署去对付燃料和弹药库。今年晚些时候计划进行为期一周的异构协作无人系统演示。

This detail through the Photoisomerization of a bound chromophore.

这种细节是通过结合的发色团的光异构。

They're not structural isomers like n-butane and i-butane, instead, they're what we call cis-trans isomers.

它们不是像正丁烷和异丁烷那样的构造异构体，而是我们所说的顺反异构体。

They're not structural isomers like n-butane and i-butane. Instead, they're what we call cis-trans isomers. These have the atoms in the same positions on the molecule, but the atoms are oriented differently in space.

它们不是像正丁烷和异丁烷那样的结构异构体。相反，它们是我们所说的顺反异构体。这些分子中的原子在分子中的位置相，但原子在空间中的取向不。

Well, and I think one of the things that it's pushing people towards is more heterogeneous computing, right?

嗯， 我认为它正推动人们走向更多样的异构计算，对吧？

But looking at this table of the number of possible isomers you could see that that escalated quickly.

但是查看这张可能的异构体数量表， 您会发现它迅速增加。

But if the parts are different, it's possible to have two totally different isomers of the same compound.

但如果这些部分不，就有可能形成一合物的两种完全不的异构体。

But pentane, C5H12, has 3 possible isomers and C6H14, known as hexane, has 5.

但是戊烷 C5H12 有 3 种可能的异构体， 而为己烷的 C6H14 有 5 种。

With the information we have, this 2-butene could be one of two different isomers: one with the methyl groups on the same side or one with the methyl groups on different sides.

根据我们掌握的信息，这个2-丁烯可能是两种不的异构体之一：一种是甲基位于一侧， 另一种是甲基位于不侧。

They call that isobutane and it is an isomer of butane, but according to these all important rules of nomenclature, it's not actually any sort of butane at all.

他们其为异丁烷， 它是丁烷的异构体，但根据所有重要的命名规则， 它实际上根本不是丁烷。

Note, by the way, that organic compounds cannot switch from cis to trans or the other way around. You would have to break the pi bond, and thus the entire molecule, to rotate between isomers.

顺便提一下，有机合物无法在顺式和反式之间相互转换。要实现异构体之间的旋转，必须断裂π键，从而导致整个分子结构发变。
