They're not made out of butyl rubber and they're not made out of latex. They're actually made out of an interesting kind of plastic compound which is super super light and I think that explains a bit of the ride feel.

它们不是丁基橡胶制成的，也不是乳胶制成的。它们实际上是由一种有趣的塑料复合物制成的，这种塑料复合物轻，我想这也是骑行感觉的一个原因。

But the researchers were able to make rubber self-heal by replacing the sulfur in the rubber with a pair of charged molecules, or ions, called butyl imidazolium and bromide.

但是，研究人员可以通过成对的带电分子或离子替换其中的硫磺使这些橡胶自行修复，叫做丁基咪唑鎓盐和溴化物。

Your saliva enzymes and your stomach acid can't touch the butyl in the gum base, but that doesn't mean it just hangs out.

你身体中的唾液酶和胃酸不会接触到口香糖原料中的丁基橡胶，但这并不表示口香糖会直接被排出体外。

The mission launched in October of 2021, but yesterday, Lucy reached its first target, an ancient asteroid called Dinkinesh.

该任务于202110月启动实施，但在昨天，“露西”号到达了它的第一个目的地，那是一颗名叫丁基内什的古老小行星。

It appears, the researchers said, that a big piece of rock broke free sometime in the past from Dinkinesh.

研究人员表示，似乎在过去的某个时候，一大块岩石从丁基内什上脱落了。

Lucy came within 435 kilometers of Dinkinesh to test its instruments for the larger asteroids that lie ahead.

“露西”号来到距离丁基内什不到 435 公里的地方，对前方较大小行星的探测仪器进行了测试。

But don't worry, the butyl in your gum won't make you sick.

但是别担心，口香糖中的丁基橡胶并不会致病。

Butyl imidazolium has a positive charge, and it's always accompanied by a negatively charged bromide, just like the ions of sodium and chloride that you find in table salt.

丁基咪唑鎓盐拥有正电荷，总是伴随着一个负电荷的溴化物，就像盐粒中的钠离子和氯离子。

The spacecraft observed ridges, trough structures and other features on Dinkinesh. Dinkinesh has a diameter of nearly 720 meters.

该航天器在丁基内什上观察到山脊、槽状结构和其他特征。丁基内什的直径近720米。

However, most gum today is made from natural or synthetic polymers, most commonly butyl rubber.

但是，如今的大多数口香糖由天然或人造的聚合物制成，其中最常见的是丁基橡胶。

Selam orbits Dinkinesh once about every 53 hours at a distance of about 3.1 kilometers.

塞拉姆大约每 53 小时绕丁基内什轨道运行一次，距离约 3.1 公里。

Some of this debris, they said, fell back onto Dinkinesh's surface to form a ridge structure.

研究人员表示，其中一些碎片又落回了丁基内什的表面，形成了一个山脊结构。

On the way, Lucy flew past Dinkinesh and Selam in the inner edge of the main asteroid belt.

在途中，露西在内侧主小行星带边缘掠过了丁基内什和塞拉姆小行星。

Understanding the properties of small asteroids such as Dinkinesh and Selam helps us to have a better picture of the earliest phases of planet formation.

理解像“丁基内什”和“塞拉姆”这样的小行星的特性，有助于我们更好地描绘行星形成的最初阶段。

I think it's really cute that Stinky's back.

我觉得斯丁基回来了真是太可爱了。

I think if Lucy Dinkis makes the same record, that'll be fine.

我觉得如果露西·丁基斯再做一张同样的专辑，那也挺好。

In a landmark analysis of four popular vaping liquids published in Chemical Research in Toxicology in 2021, a team at Johns Hopkins University labelled six ingredients—including caffeine and tributylphosphine oxide, a pesticide precursor—as potentially hazardous.

2021发表在《毒理学化学研究》上的一项具有里程碑意义的分析中，约翰斯·霍普金斯大学的一个团队对四种流行电子烟液进行了研究，并将其中的六种成分——包括咖啡因和作为农药前体的三丁基氧化膦——标记为潜在有害物质。

Multiple studies in humans have found that even heavy popper use showed no significant association with the risk of Kaposi's sarcoma, which does make sense, given that poppers are still sold everywhere in this city.

多项人类研究发现， 即使是大量使用丁基硝酸酯， 也与卡波西肉瘤的风险没有显著关联，这在一定程度上说得通， 毕竟这个城市到处都在销售这种产品。

Dinkinesh is the Ethiopian name for the Lucy fossil, meaning " you are marvelous" in the Amharic language.

“丁基内什”是露西化石的埃塞俄比亚名字，在阿姆哈拉语中意为“你太了不起了”。

If you don't have butylated hydroxytoluene that you put on your vegetables or you sprinkle on your steak, don't buy food with it.

如果你没有将丁基羟基甲苯涂抹在蔬菜上或撒在牛排上，那就不要购买含有这种成分的食物。
