摘　　要：本文首次报导了Ln(OOCCF_3)_3(Ln=Pr,Nd,Sm,Eu,Gd,Tb,Ho,Er,Tm,Yb,Lu)在甘油中的正负离子FAB谱,总结并讨论了其谱图特征。通过亚稳离子分析,探讨了某些离子碎裂和形成途径,提出了Ln(Ⅲ)→Ln(Ⅰ)可能的还原变价机制。This paper has firstry reported the positive and negative ion fast atom bombardment mass spectra of rare-earth-trifluoroacetic complexes Ln(OOCCF_3)_3 in the matrix glycerol. The ionic characteristics has been summitted and discussed. The fragmentation pathways of several ions been investigated and the reduction mechanism of Ln(Ⅲ)—Ln(Ⅰ) has been suggested by metastable the ion analysis.
