在非快速眼动睡眠期，完全没有这种反射性的调整。
This reflexive adjustment is totally absent during NREM sleep.
在白天，你的大脑就像一个活跃的蜂窝——在非快速眼动睡眠期间，它就几乎没有嗡嗡声了。
During the day, your brain is a beehive of activity—during NREM sleep, it is barely humming.
这是因为在非快速眼动睡眠中，自动的新陈代谢系统对呼吸有排他的控制，身体消耗更少的氧气，产生更少的二氧化碳。
This occurs because during NREM sleep the automatic, metabolic system has exclusive control over breathing and the body uses less oxygen and produces less carbon dioxide.
在快速眼动睡眠期发生的额外的呼吸变化，甚至比那些在非快速眼动期发生的变化还要显著。
Additional breathing changes occur during REM sleep that are even more dramatic than the changes that occur during NREM.
第二，一旦完全进入睡眠状态，非快速眼动期间血液中的二氧化碳增加，氧气减少。
Second, once sleep is fully obtained, there is an increase of carbon dioxide and a decrease of oxygen in the blood that persists during NREM.
在非快速眼动睡眠期的更深层阶段，脑活动较慢一点。
In the deeper stages of non-REM sleep brain activity is slower.
睡眠过程可分为快速眼动阶段和四个非快速眼动阶段，每个阶段的脑波频率都不一样。
Sleep is divided into REM and four stages of non-REM; each has a distinct brain wave frequency.
我们大多数人会从清醒状态转入预料中的周期：深度非快速动眼睡眠（non-REM），之后是充满梦境的快速动眼（REM）睡眠。
Most of usdrift from our waking lives into predictable cycles of deep, non-REM sleep, followed by dream-filled rapid-eye-movement (REM) sleep.
他们发现学习上的成功和第二阶段非快速眼动（NREM）相关。 NREM是深快速眼动（REM）睡眠之前的阶段。
They found that success in learning correlated with the amount of stage-2 non rapid eye movement (NREM) sleep, the stage preceding deep rapid eye movement (REM) sleep.
以长程睡眠脑电数据分析和仿真为例，分析结果表明关联维的高低能够反映出睡眠的阶段，据此对非快速眼动睡眠期的仿真预测与实际结果相符。
The value of correlation dimension can reflect sleep stages after analyzing and simulating the sleep EEG, and then simulation forecast for NREM sleep stage was made which accorded with actual result.
非快速眼动睡眠时，我们的大脑和身体活动减少，心跳变慢，呼吸均匀。
Non-REM sleep is when our brain and body slow down. Our heart rate slows and our breathing is regular.
我们还知道7个月大小的胎儿也做梦，胎儿的肌肉和眼动能清清楚楚地反映出快速眼动睡眠(rem)和非快速眼动睡眠(non - REM)信号。
We also know that at seven months a fetus is dreaming, its muscles and eye movements giving the tell-tale signs of REM (or rapid eye movement) sleep and non-REM sleep.
我们还知道7个月大小的胎儿也做梦，胎儿的肌肉和眼动能清清楚楚地反映出快速眼动睡眠(rem)和非快速眼动睡眠(non - REM)信号。
We also know that at seven months a fetus is dreaming, its muscles and eye movements giving the tell-tale signs of REM (or rapid eye movement) sleep and non-REM sleep.
