Absorption spectrum是吸收光谱的意思。以下是一篇关于吸收光谱的英文范文：
The absorption spectrum of a substance is a graphic representation of the wavelengths of light that are absorbed by that substance. In other words, it shows the spectrum of frequencies or colors of light that are no longer available to pass through the substance. This spectrum is typically obtained by placing a sample of the substance in front of a light source that is producing light of a range of wavelengths, and then monitoring the amount of light that is no longer present after passing through the sample.
The absorption spectrum of a substance can provide valuable information about its chemical composition and structure. For example, certain spectral features can be used to identify the presence of specific elements or compounds, while others can indicate the presence of structural changes or impurities. Additionally, the absorption spectrum can be used to determine the temperature and pressure conditions under which the substance was examined, as well as its state (solid, liquid, or gas).
In some cases, the absorption spectrum of a substance can be used to identify its source or origin. For example, astronomers use absorption spectra to determine the chemical composition and temperature of interstellar gases and dust clouds, which can provide valuable information about the environment in which stars and galaxies are formed.
In summary, the absorption spectrum of a substance provides valuable information about its chemical composition, structure, and environmental conditions. It can also be used to identify its source or origin in some cases.
