Chemistry is when these strings bump into each other and form molecules.

化学指的是这些弦相互碰撞产生分子。

But when hydrochloric acid dissolves in water droplets, it forms reactive ozone-depleting molecules.

但是，当盐酸溶解在水滴中时，它会形成反应性的破坏臭氧的分子。

These are also sometimes called molecular clouds; they're cold enough that atoms can stick together to form molecules.

这些云有时也被称为分子云；温度足够低，原子可以结合在一起形成分子。

You see, the body strips off a phosphate molecule from the psilocybin to form a different molecule called psilocin.

你看，人体从裸盖菇素中剥离一个磷酸盐分子形成另一种叫做裸盖菇素的分子。

The complexed calcium forms a molecule that's electrically neutral but unlike free-ionized calcium is not useful for cellular processes.

这些结合钙形成的分子是电中性的，不像游离钙，它们不参与细胞的活动。

So atoms stick together and they form molecules.

所以原子粘在一起，形成分子。

When these atoms connect to form molecules, they follow a set of rules.

当这些原子连接形成分子时，它们遵循一套规则。

A single chlorine atom can destroy thousands of ozone molecules before finally reacting with something else and forming a stable molecule.

一个氯原子可以破坏数千个臭氧分子，然后与其他物质发生反应，形成稳定的分子。

A single chlorine atom can destroy thousands of ozone molecules before it finally reacting with something else and forming a stable molecule.

一个氯原子在最终与其他物质反应形成稳定的分子之前可以破坏数千个臭氧分子。

That air flows to the sides and sinks, and sunlight changes the chemistry in the clouds forming molecules that color the air yellow, red, and brown.

当气流涌向边缘并下沉时，阳光会改变云团中的化学成分，产生把云团染成黄色、红色和棕色的分子。

For example, it can respond to decreasing pHs by getting rid of one of the most common acid forming molecules—carbon dioxide— by well, breathing a little more.

例如，它可以依靠多呼吸的方式摆脱最普通的酸性形成分子，即二氧化碳，从而对酸碱值的降低做出反应。

A Chemist and Biochemist who has published relevant research in several journals like the American Journal of Physiology, Dr. Mark Miller, says that nitrate and nitrite are not nitrosating species, that is, these molecules cannot directly form cancer causing nitrosamines.

在《美国生理学杂志》等期刊上发表过相关研究的化学家和生物化学家马克·米勒博士说，硝酸盐和亚硝酸盐不是亚硝化物质，也就是说，这些分子不能直接形成致癌的亚硝胺。

It is just a question of making a hairpin with an appropriate genetic sequence-one that is the same as the missing strand of the original DNA-so that the hairpin will combine eagerly with the messenger to form a double-stranded molecule.

问题的关键是设计出合适的发卡结构，其遗传序列必须与其替代的DNA序列一致，才能迅速准确地结合其编码的RNA成为双链RNA分子。

Standing in the station, with Paris in back of them, it seemed as if they were vicariously leaning a little over the ocean, already undergoing a sea-change, a shifting about of atoms to form the essential molecule of a new people.

站在车站里，巴黎就在他们身后，他们似乎在替代地稍微俯身在海洋上，已经在经历一场巨变，原子的移动形成了一个新民族的基本分子。
