We can figure out the chemical makeup of another star by comparing the spectrum pattern it has to the pattern of elements in the laboratory.

我们可以通过比较恒星的光谱和实验室元素的光谱来确定某颗恒星是由某种元素构成的。

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。

These patterns form the core of a pattern language covering a wider spectrum of issues around SOA and SOI as you move into higher levels of maturity in the adoption of SOA (shown below in Figure 1).

这些模式构成了模式语言的核心，当您达到SOA采用的成熟度的较高级别时，将涉及各种围绕SOA和SOI产生的问题(如下面的图1所示)。

Just as in a container, molecules in an inter-galactic gas cloud absorb certain wavelengths and leave a pattern of dark lines on a quasar's spectrum.

ECONOMIST: Fundamental physics

For all the potential that such an agreement could provide, talks between the companies are currently said to be in a holding pattern while the FCC completes its review of Dish's spectrum holdings.
