An enclosed, surface-level colony would create a much safer habitat with lower risks of narcosis and decompression sickness.

一个封闭表层生物群落将构建出一个更安全栖息地，这会降低麻醉症状减压病发生风险。

Some divers suffering from nitrogen narcosis have died from willingly removing their scuba equipment in their confused state.

一些因氮麻醉而死亡潜水员，是由于神志不清情况下，自愿摘掉了潜水设备。

To avoid inert gas narcosis, many divers fill their tanks with Heliox, which combines 21% oxygen with 79% helium.

为了避免惰性气体麻醉病症，许多潜水员会水箱中注入一种氧混合剂，这可以将21%氧气79%气混合一起。

Nitrogen too becomes highly toxic to humans at high pressures, inducing nitrogen narcosis or " rapture of the deep" , which produces a drunken-like state in the victim.

氮气高压下也会对人类产生剧毒，诱发氮麻醉，也叫做深海眩晕，这会让受害者进入一种类似醉酒状态。

Below 25 meters, inert gases like nitrogen can trigger a condition called inert gas narcosis, which alters your central nervous system, leading to faulty judgment and hallucinations similar to the effects of an anesthetic.

25米以下，像氮气这样惰性气体会引发一种叫做“惰性气体麻醉”病症，这种病症会改变人中枢神经系统，会导致你出现错误判断幻觉，类似于麻醉剂效果。
