These are combined in a chemical reaction to create ethylene dichloride, which is turned into a gas, and then, through a process called " polymerization" , it becomes a fine, white powder called polyvinyl chloride, or PVC.

它们在化反应中结合，生成二氯乙烯，变成气体，然后，通过一个叫做“聚合”过程，变成一种白色细粉末，叫做聚氯乙烯，简称PVC。

There are other areas of the body or certain situations where we want the stitches to dissolve and those dissolvable stitches or absorbable stitches are made out of either synthetic polymers or they're made out of animal intestines.

身体其他部位或某些情况下，我们希望缝线溶解，这些可溶解缝线或可吸收缝线是由合成聚合物制成，或者是由动物肠道制成。

Mr Carey made his discovery when he was testing the properties of a material made of carbon nanotubes (cylinders of carbon atoms a few billionths of a metre across) and a rubbery polymer called polydimethylsiloxane.

凯利在测试一种材性时有所发现，该材成分包含碳纳米管（直径为几纳米碳原子圆柱体）和一种名为聚二甲基硅氧烷橡胶聚合物。

The center of this disk is where the Sun was born, and it's thought that the planets formed as smaller particles of material stuck together during random collisions farther out in the disk.

这个圆盘中心就是太阳诞生地方，其他行星被认为是由较小颗粒物质在圆盘外因随机碰撞而聚合形成。

The other problem with most plastics is that there are other molecules in that material-in that base polymer-that are added there to make the plastic flexible or make it really thin, and those things are broadly called " plasticizers."

多数塑还有另一个问题，在这种基础聚合物材中，还要添加其他分子，让塑变得柔软或轻薄，这些东西被统称为“增塑剂”。

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.

指纹线宽度和它们之间距离是由我们聚合物链长度决定，同时也由系统内嵌挫折程度决定。

Inspired by the cheap slime toy that children play with all over the world, Zhang's team first created the substance in 2021 by mixing a simple polymer with borax.

从这种世界各地孩子都在玩廉价黏液玩具中得到启发，张立团队于2021年通过将一种简单聚合物与硼砂混合，首次创造出了这一物质。

It's unlikely to be the plastic itself: LEGO typically uses acrylonitrile butadiene styrene, or ABS, plastic—a highly durable polymer that keeps the pieces strong for building, or what LEGO calls " clutch power."

这不太可能是塑本身问题：乐高通常使用丙烯腈-丁二烯-苯乙烯（ABS）塑，这是一种高度耐用聚合物，能够保持积木强度，并提供乐高所谓“咬合力”。

Then, when you need new building blocks, or you need to release some energy, those polymers in your body, or new ones in your food, get broken up — by catabolic reactions.

然后，当你需要新组成部分，或者你需要释放一些能量，你体内聚合物，或者你食物中新聚合物，都会被分解——通过分解谢反应。

In DNA viruses, the viral DNA enters the nucleus and uses the host's DNA polymerase to create more copies of itself as well as viral mRNA that gets translated into viral protein.

在DNA病毒中，病毒DNA进入细胞核利用宿主DNA聚合酶完成自我复制，以及将病毒mRNA翻译成病毒蛋白质。

Combining these two advances, researchers at the Massachusetts Institute of Technology created a stretchy polymer with stiffness similar to human soft tissues.

有着这两项进步，麻省理工院研究人员 创造出一种可伸缩聚合物，其硬度和人体软组织相似。

Standard PCR tests are the best tests for COVID-19 but they can't beat the dogs with the speed of the results. The pups are winning that by a nose.

标准聚合酶链反应（简称PCR）检测是新冠肺炎最佳检测方法，但这种检测出结果速度没有狗狗快。小狗以微弱优势获胜。

It's not always " you" they're after, but your behaviors help create aggregated statistical models of people who act or watch TV the way you do.

他们追踪并不总是“你”，但你行为帮助创建了行为方式或看电视方式与你相同人聚合统计模型。
