Nitrous oxide in the sky can be destructive, but on Earth the substance can be used as a medicine.

在天上一氧化二氮是破坏性的，但是在地面上，它可以被用作一种药物。

Nitrous oxide in the stratosphere is already dangerous for life on our planet, and according to a new study, it may become even more dangerous in the near future.

平流层中的一氧化二氮对地球上的生命而言是危险的。根据一项新的研究，在不久的将来，它可能变得更加危险。

In addition, Yohimbe increases the formation of Nitrous Oxide a natural substance that is important for circulation and sexual performance.

此外， Yohimbe增加形成一氧化二氮（一种天然物质，是非常重要的流通和性的表现。

To understand why nitrous oxide is dangerous, it's important to understand what else is in the stratosphere.

为了了解为什么一氧化二氮如此危险，我们很有必要知道平流层中还有哪些物质。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
