如果你真的放大太阳光的光谱，你可以分辨出多达10万条的光谱线。

If you really magnify the spectrum of the sunlight, you could identify more than 100,000 of them.

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。

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

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。

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.

对铜合金可见光谱线进行了计算机数字模拟处理，研究了基体元素铜和各成分元素的可见光谱特征。

The visible spectrum characteristics of the copper matrix and component in Cu-based alloy were(studied) with computerized digital simulation processing technique.

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。

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.
