And they also subjected it to a technique called reflection-mode Fourier-transform infrared spectroscopy.

还对其进行了一种称为反射模式傅立叶变换红外光谱的技术。

Like Owen and Fourier and those guys.

就像欧文、傅立叶和的同道中一样。

At a later period he had spent some months in a community of Fourierists.

后来，在一个傅立叶学派社区呆了几个月。

I also put an advanced Fourier system on the main hallway chalkboard.

走廊黑板上有高级傅立叶算式。

Instead, you have to perform something called a Discreet Fourier Transform.

相反，您必须执行称为散傅立叶变换的操作。

Fourier was the first to theorize what is now known as the greenhouse effect.

约瑟夫·傅立叶是第一个提出现在被称为温室效理论的。

But in Fourier's dictionary, we find one of the first recorded uses of that new pronoun form.

但在傅立叶的字典中，我发现了这种新代词形式最早的记录之一。

They needed to know how much of different frequencies were present which meant they needed to take a Fourier transform.

需要知道存在多少不同的频率，这意味着需要进行傅立叶变换。

To complete one discrete Fourier transform requires multiplying N data points by N different frequency waves.

要完成一次散傅立叶变换，需要将 N 个数据点乘以 N 个不同频率的波。

Basically, anytime a signal is processed, there's a good chance that a Fast Fourier Transform is involved.

基本上， 每当处理信号时，很有可能涉及快速傅立叶变换。

And one of the distinguishing features of a Discreet Fourier Transform is that the frequency spectrum is also discreet and finite.

散傅立叶变换的显着特征之一是频谱也是散且有限的。

And there's also a really excellent video on the channel reducible, talking about the fast fourier transform, which is an algorithm for computing these more quickly.

还有一个关于通道可简化的非常出色的视频，谈论快速傅立叶变换，这是一种用于更快地计算这些的算法。

The real obstacle to detecting underground explosions wasn't the accuracy of the seismometers, it was the vast amounts of computation required to Fourier transform the seismometer signals.

探测地下爆炸的真正障碍不是地震仪的精度，而是对地震仪信号进行傅立叶变换所需的大量计算。

Around the same time that America's landscape was being altered, in the 1820s, Joseph Fourier, a French mathematician, began studying the Earth's temperature, and he made an important discovery.

大约在同一时期，也就是19世纪20年代，法国数学家约瑟夫·傅立叶开始研究地球的温度，并做出了一个重要发现。

Remember, again, that poverty is extinct, and that the Fourierist phalangsteries and all their kind, as was but natural at the time, implied nothing but a refuge from mere destitution.

再次记住，贫困已经绝迹，傅立叶主义的方阵和其类似的东西，在当时是很自然的，只不过是为了逃避贫困而已。

Filtering that out, by just smushing the spike down, what you'd be looking at is the Fourier transform of a sound that's just like your recording, only without that high frequency.

通过将尖峰压扁， 将其过滤掉，您将看到声音的傅立叶变换， 就像您的录音一样，只是没有高频。

Fourier calculated that due to the Earth's size and distance from the Sun, it should be far cooler than it is, which led him to propose that the Earth's atmosphere insulated the planet.

傅立叶计算出， 由于地球的大小及其与太阳的距，地球该比实际温度低得多，这促使提出地球大气层具有保温作用。

So on your computer, most of the images will be saved in this form as a two dimensional Fast Fourier Transform and then when you wanna look at the picture again, the computer simply inverts the transform.

因此，在您的计算机上， 大多数图像将以二维快速傅立叶变换的形式保存， 然后当您想再次查看图片时，计算机只需反转变换即可。
