1·So how do we know which spectral patterns match up with which elements?

那么我们如何知道哪些光谱模式与哪些元素相匹配呢？

2·I want you to notice that this spectrum is interrupted by dark lines called spectral lines.

我想让你们注意到的是，这一光谱是被叫做光谱线的暗线所打断的。

3·There was a pretty extensive library of spectral line patterns of elements even by the 1860s.

甚至在19世纪60年代，就已经有了一个相当广泛的元素谱线模式库。

4·Using ultraviolet light, we can see the spectral signature of each component part of the pigment.

通过利用紫外光，我们可以看到颜料各个组成部分的光谱特征。

5·Spectroscopy is basically the study of spectra and spectral lines of light, and specifically for us, the light from stars.

光谱学基本上是一种研究光谱和光谱线的学科，特别对我们来说，是研究恒星发出的光。

6·A British astronomer was analyzing a spectrograph of sunlight, and he noticed a particular pattern of spectral lines that didn't match anything in the library.

一位英国天文学家在分析一台太阳光摄谱仪时，注意到一种特殊的光谱线模式，它与图书馆里的任何一种都不匹配。

7·Each pattern stands for a distinct chemical element, and so different sets or patterns of spectral lines mean that the star has a different chemical composition.

每一种样式代表一种不同的化学元素，所以光谱线的不同集合或模式意味着这颗恒星有不同的化学成分。

8·This light is passed through a prism, which breaks it up into a spectrum, and a unique pattern, kind of like a chemical fingerprint of spectral lines for that element appears.

铁块会一直加热，直到到达某一燃点，便会辐射出光来；而当它的光线穿过一块棱柱时，棱柱就会分割光线，形成光谱。

9·She is compelling, spectral, fascinating, an unforgettably unique performer.

她的表演很有吸引力，如鬼魅一般，令人着迷，令人难忘，是一个独特的演员。《柯林斯英汉双解大词典》

10·The detailed structure of spectrum of atmospheric tides is obtained by the spectral analysis-and harmonic analysis from the microbarograph records.

根据微气压计记录采用频谱分析和调和分析两种方法得出了大气潮谱的详细结构。
