Unfortunately, it has been shownthat these methods are not suitable to study about chemical bonds due to not involvingchemical bonds. In order to consider chemical bonds obviously, we have proposed an atom-bondelectronegativity equalization model on the basis of density-functionaltheory and electronegativity equalization principle. The main contents of our atom-bond electronegativity equalization model contain:(1)Considering the fact that there are varies of chemical bonds in molecules andpartitioning the molecular electron density as summations of atomic electron densitiesand chemical bond's electron densities, we obtained the basic equations of atom-bondelectronegativity equalization model: the expression of the total energy 〓, theexpression of the atom electronegativity 〓 and the expression of the bondelectronegativity 〓.
为了明确地考虑和处理分子中存在的化学键,以便能够更好地描述体系中的电荷分布进而准确地描述分子体系中的有关物理化学性质,尤其是与化学键有关的物理化学性质,我们在密度泛函理论和电负性均衡原理基础上提出了原子-键电负性均衡模型,原子-键电负性均衡模型的主要内容是:(1)考虑到分子体系中存在各种化学键这个事实,将分子空间看成是由原子区和化学键区组成的,将分子的单电子密度表达成为分子中各组成原子的单电子密度和各化学键的单电子密度的加和,从而得到了原子-键电负性均衡模型的基本方程:分子体系总能量〓和分子中原子电负性〓和化学键电负性〓表达式。

This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.

The results of this work indicate that the humic macromolecule is composed of many humic molecules with different relative molecular mass and chemical compositions. These humic mo lecules are probably the humified products of various compounds in different hum ification processes. This implies the heterogeneous and complex compositions of the humic acid geomacromolecules.
