In this paper, the bond market listed companies, from government policies, credit rating, the phenomenon of internal control, lack of security bonds, bonds and other varieties of single-level analysis of the corporate bonds of listed companies failed to become the main form of direct financing of the reasons,And from government control, regulate credit rating, improve the ownership structure of listed companies, the implementation of strict enterprise security and bankruptcy system, the bond layer breeds innovation by the listed companies to strengthen the bond financing measures.

本文通过上市公司债券市场的问题，从政府政策、信用评级、内部人控制现象、债券安全性不足、债券品种单一等层面分析了企业债券未能成为上市公司直接融资的主要形式的原因，并分别从加强政府调控、规范信用评级、改进上市公司股权结构、实施严格的企业担保及破产制度、债券品种创新等层而提出加强上市公司债券融资的措施。

The growth of convertible bond in China will come into a new page with the declaration of 《The management of convertiable bond for listed company》and the upsurge of convertible bond financing of listed company recently It is very necessary.to understand and analyz its features and its practice also summarize lessons expeirences in China.

因此了解和深入分析可转换债券的性质和它在中国的产生与发展，以及总结其在中国证券市场上的失败教训和成功经验非常有必要。

The metallic bond has made develop the energy band theory arriving at a metallic bond , concrete annotation of model angry from classical free electron the nature that the metallic bond forms and metal crystal physical property.

金属键由经典的自由电子气模型发展到金属键的能带理论，具体地诠释了金属键形成的本质与金属晶体的物理性质。

However, the thermal stability of metallic coordination polymer hardly enhanced in comparison with the polymer never coordinated transitional metallic ions. The reason might be that the energy of coordinate bond formed between metallic ion and polymer was trival in comparison with that of covalent bond in polymer. It started with coordinate bond when the coordinate polymer decomposed under high temperature, so it engendered little for the thermal stability at high temperature.

而金属配聚物较未配位金属的配体高温热稳定性提高不大，可能是由于金属离子与配体之间形成配位键的键能与配位体内的共价键键能相比要小得多，当金属配聚物受热裂解时，首先从配位键开始，因此对高温热稳定性的影响甚微。

Bond Form: The Pennsylvania mortgage broker bond form scares many bonding companies away from the bond.

债券形式：宾夕法尼亚抵押债券形式的经纪人远离惶恐许多担保公司债。

The results show that the sturcture of each of Tin clusters is obtained by capping one Ti atom to the Tin-1. The Natural bond orbital analysis show that the 4s , 4p, 4d orbitals hybridizes with 3d orbital, and about one electron transfer from 4s orbital to 3d orbital. Moreover, the electrons also transfer between different atom. The results also indicate that the average bond length of clusters were determined by the 4d and 3d orbitals except Ti7. But for Ti7, the average bond length only depend on 3d orbital.

研究结果表明： Tin(n=2~7)团簇都依带帽的形式在前一个团簇的结构基础上加一个原子变化而来；通过自然轨道分析发现，团簇原子的轨道存在sp-d杂化，有大约一个电子从4s转移到了3d，原子之间亦存在电子转移，而且除Ti7外，团簇键长由最外层4d轨道电子和3d轨道共同决定，在Ti7中，团簇键长由3d轨道决定。

On the other hand, in the ground state of NiSin(n=1-6) and Ni2Sin(n=1-6) clusters, electronic charges is transferred from Si-Si bond to Ni-Si bond, forming Ni-Si covalent bond, and the Mulliken overlap population of Ni-Si is positive, which I'orming bonding orbital and contribute to the stability of clusters.

另外，基态NiSi_n(n=1-6)团簇中，电荷从Si-Si键向Ni-Si键转移，形成Ni-Si共价键，Ni-Si重叠布局为正，为成键轨道，增强团簇的稳定性。

The eighth chapter begins with discussion and empirical demonstration of Chinese benchmark rate, simulates and regresses the benchmark yield curve of Chinese bond according to the latest data, reviews factors having influence on Chinese benchmark yield curve through principal components analysis, illuminates the inescapability of regulation of Chinese bond yield structure through the comparative study on American bond yield curves with different terms.

第八章开始是对我国的基准利率进行探讨和实证分析，接着根据最新的数据来模拟和回归出我国国债的基准收益曲线，在此基础上运用主成分分析法考察了影响我国基准收益曲线的因素，并通过对美国不同期限国债收益率曲线的比较研究，来说明我国国债收益率结构的调整具有不可避免性。
