By contrast, Au atoms with a larger nuclear charge but a similar atomic radius to silver owing to the lanthanide contraction are able to have a stronger interaction with CO.

这主要是因为镧系收缩产生的结果：与银相比金带有更多的核电荷，但是因为镧系收缩原子半径却和银几乎一样，因此更容易跟电子给予体的一氧化碳相互作用。

Substantial researches on lanthanide carboxylate complexes have been investigated in the last two decades with rapid development of single-crystal diffraction technique; however, most of which merely are with a view to single or sporadic studies.

随着单晶衍射技术的快速发展，近年来稀土羧酸类配合物晶体结构的研究日益兴起，但大多数的研究仅仅着眼于单一或零星研究，系统性的研究工作不多。

The results indicate that the weak election-withdrawing group 4-hydroxymethyl in 4-position of pyridine in 4-HMDPA could weaken the fluorescence intensity of the lanthanide complexes. The contradistinctive experimental results show that the fluorescence intensities of these complexes are related to pH value of the aqueous solution and the dipole moment of solvent molecule: in the neutral aqueous solution,the fluorescence intensities of these complexes were strongest,while the less the dipole moment was,the stronger the fluorescence intensity was.

结果表明，在吡啶4位引入弱吸电子基团4-羟甲基会减弱稀土配合物的荧光强度；在水溶液中稀土配合物与溶液的pH值有着密切的关联，中性水溶液中荧光强度较大；分子偶极矩较小的溶剂中稀土配合物荧光强度较强。

The functional groups which are placed at 4-position of pyridine-2,6-dicarboxylic acid can effect the electron cloud of the lanthanide complexes.

吡啶-2，6-二甲酸的4位取代官能团能影响配合物的电子云形状，配合物的荧光性能和电子能量传递密切相关。
