In lunar science, volatiles are defined as chemical elements and unstable compounds, evaporating, sublimating or flowing in other ways at low temperature. At moderate temperature, vapor transfers its flowing elements from solid materials to coexisting gas phases. Such substances include S, Cu, Zn, As, Se, Ag, Cd, In, Te, Hg, Tl, Pb, Bi and halogens (F, Cl, Br, I). These volatile substances are mainly added by small impactors, so they should be uniformly deposited in lunar regolith. In the PSRs of the lunar polar region, the extremely low temperature may allow the solar activity record to be kept longer. When the lunar soil is heated, it will release volatile elements in the form of gas, especially the particles injected into the lunar soil by the solar wind. In deeper lunar soil, it means that these particles were implanted in different periods of solar evolution. The study of regolith in polar PSRs may help to solve this problem, because it has not been widely heated and therefore may not be subjected to post-implantation modification. The research on volatiles detection in lunar polar region can help us confirm the content and distribution of water ice in the permanent shadow region of the lunar polar region, and the composition, distribution, source, transport and loss mechanism of other volatiles in this region, as well as the relationship between lunar soil in the polar region and the ancient solar wind environment, and the environment and mineral resources in the region.Chandrayaan-3 provided significant assistance to the conceptualization of this project. At the end of the article, we discussed the lunar orbit.
