To counteract this oxygen would have to be diluted with non reactive gas.

为了制造这种情况，氧气中的空气比率需要利用惰性气体来降低。

I mean, I love that you said you are looking for ways to re-tweak the fundamental design of the system to discourage some of the reactive behavior, and perhaps -- to use Tristan Harris-type language -- engage people's more reflective thinking.

我是说，我喜欢说正在寻找方法来重新调整系统的基本设计，以阻止某些反应行为——使用特里斯坦·哈里斯式的语言——人们更有反思的想法。

So when you're in any situation in life, you can choose to be reactive or proactive, but the basic idea is that by choosing to be proactive, you choose to increase your circle of influence.

没有药，没有类似的东西吗？— 不，我们现在开始反应了。

This is because the internet is a novelty machine, something dopamine is particularly reactive to.

这是因为，网络是新奇的设备，多巴胺尤其容易对新奇事物起反应。

While the human body secretes multiple enzymes to protect itself from these effects, under high pressure the production of these highly reactive species overwhelms a cell's ability to protect itself, destroying the cell.

虽然人体能分泌多种酶来保护自己免受这些影响，但在高压下，这些高反应性物质的产生压倒了细胞保护自身的能力，并最终摧毁。

As a result, AA is both highly reactive and heck-a explosive.

结果就是，AA高度不稳定，而且非常容易爆炸。

'Cause the thing about oxygen is that it's super reactive.

因为氧气是超级活性的。

Overworked hair cells can also generate dangerous molecules called reactive oxygen species.

过度使用的毛细胞 也有可能会产生危险分子，称为活性氧类。

This means that these muscle cells become less reactive to stimuli.

这意味着这些肌细胞对刺激的反应性降低。

Free radicals are highly reactive chemical entities that can damage cells.

自由基是能破坏细胞的、有高反应活性的化学实体。

Crucially, in that gel were plenty of thioketals, compounds that fall apart when exposed to reactive, oxygen-containing molecules, plus just a sprinkle of titanium dioxide--an inert material that, when exposed to ultrasound, releases just those molecules.

至关重要的是，这种凝胶中含有大量的硫酮化合物，这种化合物接触到活性的含氧分子就会分解，外加少量二氧化钛--一种惰性物质，暴露在超声波下时，这些分子就会被释放。

So, because the body's so connected and is so reactive to each different aspect of life, because the body's all about maintaining homeostasis, which is sort of a balanced state within the body.

因为身体是如此的相互联系并且对生活的各个不同方面都有如此敏感的反应，因为身体的功能就是维持体内平衡，也就是身体内部的一种平衡状态。

Great. And, number three: If you want to improve your English, should you be a) reactive, b) preactive or c) proactive when you're learning new words?

很好。3：如果想提高的英语，学习新单词时应该 a) reactive，b) preactive 还是 c) proactive。

Scientists at the University of Hertfordshire [UK] asked volunteers to play with the simple reactive robot. The same robot was then programmed with an algorithm to make it playful and curious, and they compared what people thought.

英赫特福德郡大学的科学让志愿者和这个简单的反应型机器人玩耍。然后，他们给同一个机器人编入算法，让它更有趣、更有好奇心，然后对比人们对两种机器人的看法。

And it's thought that radiation generates reactive oxygen species in the tissue, which ultimately leads to inflammation over time, and causes myocardial fibrosis, or fibrosis of the heart muscle tissue, which makes the tissue stiffer and more restrictive.

它被认为是因为辐射会在组织中产生很多活性氧物质，随着时间推移最终导致炎症，导致心肌纤维化，或者说心脏肌肉组织的纤维化，即导致组织更加僵硬、受限。

Scientists are now pretty certain that the early atmosphere was nothing like as primed for development as Miller and Urey's gaseous stew, but rather was a much less reactive blend of nitrogen and carbon dioxide.

科学们现在相当肯定，早斯的大气根本不像米勒和尤里的混合气体那样已经为生命的形成作好准备，而是一种根本很不活泼的氮和二氧化碳的混合物。
