This is our F nears machine which is functional near-infrared spectroscopy.

是我们的近红外光。

New ways of using a mass spectroscopy machine may produce uncompromised evidence.

方法使用质器进行分析，样则会产生完全可靠的证据。

Initial mass spectroscopy suggested proteins were involved, but shed no light on which.

最初的质分析表明涉及蛋白质，但并没有阐明具体是哪种。

A near-infrared spectroscopy (NIRS) machine records and displays the patterns of information flow.

一台近红外光进行记录并且显示了信息流的状态。

It also meant that spectroscopy became a force, say it with me now: for science.

也意味着光学成为了一种力量，现在跟我一起说：为了科学。

The infrared spectroscopy matched paint fragments in the head wound to the proximal line of pipe wrenches.

红外光显示死者头部伤口的油漆残片与管钳的近似线吻合。

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

他们还对其进行了一种称为反射模式傅立叶变换红外光的。

Yes, and this is a good example of how important spectroscopy is in astronomy.

是的，是光学在天文学中的重要性的一个很好的例子。

This is known as spectroscopy and is a major feature of JWST's science instruments.

被称为光学，是 JWST 科学器的一大特色。

But today, you learned about how to analyze the composition of a light source using diffraction grating and spectroscopy.

但是今天，您了解了如何使用衍射光栅和光分析光源的成分。

They used a technique called Raman spectroscopy to confirm that it really was plastic and not, say, bits of crayfish exoskeletons.

他们使用一种称为拉曼光的来确认它确实是塑料的，而不是小龙虾外骨骼的碎片。

From infrared spectroscopy of minerals deposited on its surface they determined that, yes, it had been buried at some point.

根据沉积在其表面的矿物的红外光，他们确定，是的，它曾在某个地方被掩埋过。

The amazing thing about spectroscopy is that we can use it to look at stuff that's right around us or across the galaxy.

光学的神奇之处在于我们可以用它来观察我们周围或银河系中的东西。

The authors of this new paper published in the journal Nature used a technique called vibrational spectroscopy to figure out the composition of tiny pockets in the Greenland rocks.

发表在《自然》杂志上的篇论文的作者使用一种称为振动光学的来弄清楚格陵兰岩石中微小口袋的成分。

Participants in these studies wear a special sensor that uses spectroscopy to measure near-infrared light absorption; you see, red blood cells absorb light differently when they're carrying a lot of oxygen.

些研究的参与者会戴上一个特殊的传感器，它使用光来测量近红外光的吸收；你看，红血球携带大量氧气时吸收光的方式不同。

Using a technique called spectroscopy, they were able to see that the light shining from the galaxy's edges seemed to come from very hot sources rich in helium but essentially devoid of heavier elements.

利用名为“光学”的，他们发现从星系边缘发出的光，似乎来自非热的光源，而个光源富含氦元素但基本上不含重元素。
