TiO2, fine-grained aggregates等等，应该是物理吸附在月壤颗粒上的
The helium-3 found in the lunar soil comes originally from the Sun. A stream
of particles from the Sun, called the solar wind, contains helium-3 which
is deposited on the Moon's surface.
The factors taken into account by the researchers in mapping the likely
abundance of helium-3 in a given area of the Moon are the exposure age of
the Moon's surface matter, or regolith; the amount of helium-3, arriving
from the Sun in the solar wind and the titanium content of the lunar soil.
Older regions of the Moon's surface should be better sources of helium-3
because they have been exposed to the solar wind longer and contain greater
amounts of fine-grained aggregates that absorb helium-3.
Taking this into consideration, the scientists estimate that the greatest
amounts of helium-3 will be found on the far side in the maria, or "seas,"
of the Moon.
Helium-3 could also be found in near side areas where high concentrations of
titanium dioxide help trap the isotope.
