| 摘 要： | Clementine UVVIS and NIR data from the lunar sampling sites (totaling 46 sampling sites) were processed and used to refine the iron determination method of Le Mouéic et al. (2000, 2002). We found that about 21 sampling sites are unsuitable to Le Mouéic et al's spectral parameters ("slope" and "depth l") because their 1500 nm filter could not be used as spectral parameters' right shoulders and to evaluate the depth of the 1-μm absorption feature accurately. We used the rest 25 sampling sites to refine the method developed by Le Mouéic et al. (2000, 2002 ) and obtained our own equation of FeO content determination. We tested our own equation, and the results are satifactory. In our work we also acquired some useful experiences in scientific applications of our own dataset of the Chang'E-1 mission.

| Abstract: | Clementine UVVIS and NIR data from the lunar sampling sites (totaling 46 sampling sites) were processed and used to refine
the iron determination method of Le Mouéic et al. (2000, 2002). We found that about 21 sampling sites are unsuitable to Le
Mouéic et al’s spectral parameters (“slope” and “depth 1”) because their 1500 nm filter could not be used as spectral parameters’
right shoulders and to evaluate the depth of the 1-μm absorption feature accurately. We used the rest 25 sampling sites to
refine the method developed by Le Mouéic et al. (2000, 2002) and obtained our own equation of FeO content determination. We
tested our own equation, and the results are satifactory. In our work we also acquired some useful experiences in scientific
applications of our own dataset of the Chang’E-1 mission. |
