| 摘 要： | Polarization and radiation measurements and microwave studies show that the planets and the great majority of asteroids in the solar system are covered by soils similar to regolith on the moon surface.The soils repesent the composition of the asteroids and the geological elements of the planets. The spectral reflectance shows a tendency of decreasing from near ultraviolet,visible to near-infrared in order of LL→L→H→H with increasing Fe^0/Fet rato and toward to absorption for Jilin,Xinyang and Zanoyang ordinary chondrites and Qinzhen enstatite chondrite recently fallen in China,The same chemical group of meteorites feature deeper absorption valleys with increasing metamorphic grade.The spectal reflectance of igneous rocks varies from strong to what is like that of H-group chondrites in order of acid→basic→ultrabasic rocks.

| Abstract: | Polarization and radiation measurements and microwave studies show that the planets and the great majority of asteroids in
the solar system are covered by soils similar to regolith on the moon surface. The soils repesent the composition of the asteroids
and the geological elements of the planets. The spectral reflectance shows a tendency of decreasing from near ultraviolet,
visible to near-infrared in order of LL → L → H → E with increasing Fe0/Fet rato and toward to absorption for Jilin. Xinyang and Zaoyang ordinary chondrites and Qinzhen enstatite chondrite recently
fallen in China. The same chemical group of meteorites feature deeper absorption valleys with increasing metamorphic grade.
The spectral reflectance of igneous rocks varies from strong to what is like that of H-group chondrites in order of acid →
basic → ultrabasic rocks. |
