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.

我打量着她的前额，那上面会不会偶然出现一个皱纹，告诉我她正在衰减的热情。

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

亮度衰减需要一定的时间。

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，伽马辐射的量以及它如何随时间衰减是非常独特的，而7月2日的件起来与此完全不同。

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的差异来估计这种矿物质的。

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

首先，他们的放射性铀含量衰减成铅的速度可以用来计算他们的。

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

2006发的大肠杆菌疫情有多大程度的衰减?

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

它们的衰减是由人类活动造成的，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.

河道中的水将氧气挡在外面，保存着各种通常衰减的有机物质。

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的衰减比对低频声音的衰减更大。

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

自然环境中的混响会随着音频信号的衰减而减弱。

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的文章。

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

嗯，它确实会衰减，但衰减的程度与距离成正比。

It's almost certainly a rapidly decaying orbit.

这几乎可以肯定是条快速衰减的轨道。

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?

以这样的方式移动， 使你的速度始终与这个翻转并压缩的位置向量匹配，你会朝相反的方向移动， 以指数衰减的方式减速趋向于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的人口比例呈衰减的 S 形，在增长的初始阶段缓慢上升， 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.

我期待着从波尔多送来的一箱东西，里面有一些物品，我希望能作为我对您永不衰减的感激之情的象征赠予您。

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.

半衰期较长的那些衰减得更慢， 释放的能量更少，但这意味着它们需要非常非常长的时间才能稳定下来。

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，衰减的频率和环境噪音起到了一种毯子的作用，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里发射的无线电波传播的距离相对很小，并且早已衰减成无法读取的噪声。
