摘　　要：根据ＪｕｄｄＯｆｅｌｔ理论，测定并计算了稀土配合物在不同溶剂中的振子强度，讨论了不同配位场强对稀土离子振子强度的影响。通过Ｈｏ３＋，Ｅｒ３＋超灵敏跃迁振子强度对Ｎｄ３＋超灵敏跃迁振子强度作图，发现几条直线的反向延长线基本趋于一点，交点坐标代表最小配位影响强度值。The oscillator strengths of the absorption spectra for rare earth complexes in different solvents were determined and calculated on the basis of the JuddOfelt theory. The effect of different ligand field strengths on the oscillator strengths of lanthanide ions is discussed. In plotting of the oscillator strengths of the hypersensitive transition of Ho3+, Er3+ against those of Nd3+, the reverse extending lines of the straight lines were found to intersect at a point on the whole. The coordinates of the crosspoint are believed to represent the strength value of the smallest coordinated effect.
