And when rocks melt and reform anew, all evidence of that decay is destroyed.

I scanned her brow for any passing line that might indicate a settling emotion.

我打量前额，看那上面会不会偶然出现一个皱纹，告诉我正在衰减热情。

It takes a certain amount of time for that brightness to dissipate.

亮度衰减需要一定时间。

The amount of gamma radiation and how it fades with time are very distinctive for a nuclear weapon, and the July 2 event looked completely different than that.

对于核武器来说，伽马辐射量以及它如何随时间衰减是非常独特，而7月2日事件看起来与此完全不同。

They then estimated the age of the mineral based on differences in the decay of the radioactive uranium to lead over time.

然后，他们根据放射性铀随时间衰减成铅差异来估计这种矿年。

First, their content of radioactive uranium decays to lead at a rate that can be used to calculate their age.

首先，他们放射性铀含量衰减成铅速度可以用来计算他们年。

ALESCI : How much of a setback was the outbreak in 2006 of E. coli?

2006年爆发大肠杆菌疫情有多大程度衰减?

Their collapse is being driven by human activity, everything from traffic to industrial farming and pesticides to light pollution.

它们衰减是由人类活动造成，包括从交通到工业化农场，从杀虫剂到光污染。

And the water in the channel keeps the oxygen out, preserves all sorts of organic materials that normally decay.

河道中水将氧气挡在外面，保存各种通常衰减有。

And the second cue is that this shadow attenuates higher frequencies more than low frequencies.

第二个线索是，这个阴影对高频声音衰减比对低频声音衰减更大。

Reverb in a natural setting tends to fade as the audio signal decays.

自然环境中混响会随音频信号衰减而减弱。

Jean Twenge just had a sub stack about the rapid decline of reading.

珍·特温奇刚刚在Substack上发布了一篇关于阅读迅速衰减文章。

Well, it does dissipate, but it's proportional to the distance.

嗯，它确实会衰减，但衰减程度与距离成正比。

It's almost certainly a rapidly decaying orbit.

这几乎可以肯定是条快速衰减轨道。

Moving in such a way that your velocity always matches this flipped and squished copy of the position vector, you'd go the other direction, slowing down in exponential decay towards 0. What about if the constant was i?

以这样方式移动， 使你速度始终与这个翻转并压缩位置向量匹配，你会朝相反方向移动， 以指数衰减方式减速趋向于0。 如果常数是i呢？

The fraction of a country's population living in cities follows an attenuated s shape, rising slowly during an initial stage of growth, more quickly during an acceleration stage, then slowing and flattening off during a terminal stage.

一个国家居住在城市人口比例呈衰减 S 形，在增长初始阶段缓慢上升， 在加速阶段上升更快， 然后在末期放缓并趋于平缓。

I am expecting a case from Bordeaux which contains a few things which you must allow me to offer you as a mark of my unceasing gratitude.

我期待从波尔多送来一箱东西，里面有一些品，我希望能作为我对您永不衰减感激之情象征赠予您。

The ones with longer half-lives decay more slowly, release less energy but that means it takes a very, very long time for them to stabilize.

半衰期较长那些衰减得更慢， 释放能量更少，但这意味它们需要非常非常长时间才能稳定下来。

In addition, the dampened frequencies and environmental noise act as a blanket that blends the music together and pushes it into the background using spatialization.

此外，衰减频率和环境噪音起到了一种毯子作用，将音乐融合在一起，并通过空间化将其推到背景中。

The radio signals we've transmitted in the last 100 years traveled a relatively tiny distance and have long decayed into unreadable noise.

我们在过去100年里发射无线电波传播距离相对很小，并且早已衰减成无法读取噪声。
