结果表明，铁肥树干强力高压注射，主要以二价铁(Fe2+)沿中央木质部的导管运输，大部分向下运输，使铁在根中大量贮存；向上运输较少，运输速度为每小时数百厘米，矫正缺铁失绿症的速度比根系输液慢，但由于根中贮存大量的铁，持效期较长。

Topological indexes of A , B , C and D were all obtained from the different combination of topological vertex degree. A QSAR equation for this series of compounds was established based on the multi-linear regression method and a new group of autocorrelation topological indexes. The results showed that the biological activity is linearly correlated with the volume and branching size of the quinclorac derivatives. Finally, new herbicide was designed based on all QSAR results.

针对应用经典结构参数和量子化学参数得出的结果不够理想的问题，对点价自相关拓扑指数进行了研究，建立了一组新型的点价自相关拓扑指数A、B、C、D；首次将该指数用于除草剂氯喹酸酯类化合物的定量构效关系研究中，建立了很好的定量构效关系方程，综合分析所有的QSAR结果设计出了潜在的新型除草剂氯喹酸烯丙酯。

In this paper, the stable Au complexes are classified according to the coordination atoms and their characteristic structure. The recent development of the researches on the antitumor activity of Au complexes including the structure-activity relationship, biological targets and the mechanisms of action are reviewed. The structure of the coordination ligand and the leaving group have great impact on the in vitro cytotoxicity of the Au complex. Many physical and biological methods are introduced to study the interaction between the Au complexes and the suspected bio-target, such as DNA, protein, mitochondrion, thio-containing biomolecules, etc. The interaction modes (intercalating, electrostatic interaction, covalent bonding, etc.) are focused to illustrate the reason for the antitumor activity of Au complexes.

本文按配位原子的不同总结了稳定三价金配合物的结构特征，按其生物活性的构效关系、生物靶点和作用机制综述了三价金配合物抗肿瘤活性研究的最新成果：配体的结构特点以及离去基团对三价金配合物的体外细胞毒性影响较大；介绍了用于检测三价金配合物与可能的生物靶分子之间的相互作用的多种物理和生物学方法，重点关注了相互作用的模式，如嵌入/静电吸引/共价结合等，并解释了三价金配合物抗肿瘤活性的原因。
