摘      要：Helium-3(3He) implanted by solar wind in the lunar regolith is a valuable resource because of its potential as a fusion *** the basis of the Apollo regolith samples,a linear relationship between 3He abundance and solar wind flux,optical maturity and TiO2 content has been *** successfully launched its first lunar exploration satellite Chang-E 1(CE-1) on October 24,2007.A multi-channeled microwave radiometer was aboard the satellite with the purpose of measuring microwave thermal emission from the lunar surface *** the multi-channel brightness temperature(Tb) observed by CE-1,the global distribution of the regolith thickness was inverted from the multi-channel Tb,and was used to evaluate the total amount of 3He per unit area in the lunar *** global inventory of 3He was estimated as being 6.6×108 kg;3.7×108 kg for the lunar nearside and 2.9×108 kg for the lunar farside.
