顺磁性金属

在配合物中，两个顺磁性金属离子间需要间隔一个或多个抗磁性原子才能使相转移温度有一定程度的提高。

In this kind of complexes , one or more diamagnetic atoms are between two paramagnetic metal ion .

这类配体依靠RGD序列的多肽引导其肿瘤组织靶向性，通过棕榈酸长链的接入实现两亲性，与顺磁性金属离子配位之后有望成为一种新的双亲性靶向MRI造影剂。

These ligands are compose of RGD peptide and long-chain palmitic acid . If coordinated with Gd3 + , the complex were expected to be an new amphiphilic and tumor targeted MRI contrast agent .

通过对比实验分别研究不同含有顺磁性金属离子溶液及其饱和岩样的弛豫特性，为核磁共振测井提供了基础的实验数据。

The relaxation characteristics are investigated with experiments of ion solutions of different paramagnetic melals and saturated core samples , which provides basic experimental data for nuclear magnetic resonance log .
