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。

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。

The state takes on Exxon Mobil and its lawsuit over the oil giant's use of the gas additive MTBE.

该州控告头埃克森美孚使用汽添加剂甲基叔丁基醚。

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。

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。

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造的聚合物制成，其中最常见的是丁基橡胶。

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。

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

员表示，似乎在过去的某个时候，一大块岩从丁基内什上脱落了。

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

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。

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

该任务于2021年10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's got elevated levels of dibutoxyethanol, methane, and benzene.

亚乙基二醇二丁基 甲烷和苯的含量，严重超标。

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

“丁基内什”是露西化的埃塞俄比亚名字，在阿姆哈拉语中意为“你太了不起了”。

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。

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。

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，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。

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。

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，这种塑料复合物超级超级轻，我想这也是骑行感觉的一个原因。

Then in the 1950s, a new BIO side compound was developed, a compound called tributyl tin, or t BT p BT based paints were so effective that they were seen to be the perfect product for preventing BIO fouling.

然后在 1950 年代， 开发了一种新的 BIO 侧化合物，一种称为三丁基锡或 t BT p BT 基涂料的化合物非常有效， 以至于它们被视为防止 BIO 污染的完美产品。
