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.

So we can figure out the chemical make up of the other stars by comparing this spectrum pattern it has to the pattern of the element in the libraries.

所以我们可以我们可以通过以库中的光谱样式和它们有的光谱样式来进行对比从而估算出别的行星的化学成分。

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。

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.

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.
