In this section, applying the method, from abstract to specific and from history to present, it analyzes the operation mechanism of urbanization economy affected by market mechanism; puts forward four theories of urbanization economy from economic perspective, including agriculture surplus and comparison advantage; non-agricultural industry; agglomeration economy and spillover effect, on this basis of the theories, it, on one hand, analyzes two kinds of internal mechanism in the chronologic operation of urbanization economies: increasing mechanism of urbanization economies in urban output industry; and changing mechanism from specialization to integration, which are the representations of the evolution of "mart" development; on the other hand, it analyzes two internal mechanism of dimensional operation of urbanization economy: internal spatial enlargement mechanism of urbanization economies from monocentric city to multi-center city, and external spatial enhancement mechanism which represents city-regionalization and city-chain connection, the later two mechanism represent the evolution of "polis" development.

这一部分，按照由抽象到具体和由历史到现代的研究方法，分析了市场机制作用下的城市化经济运行机理，从经济学角度提出了农业剩余与比较优势、非农产业、聚集经济、外溢效应四大城市化经济定理；在此基础上，一方面分析了城市化经济运行沿时间增长的两个内在内容提要机制：城市输出产业的城市化经济增长机制和从专业化到综合化的城市性质变迁机制，它们主要表现为&市&发展的延续；另一方面分析了城市化经济运行沿空间增长的两个内在机制：从单中心到多中心的城市化经济运行的内部空间扩展机理和表现为城市区域化、城市连绵体的城市化经济运行的外部空间扩展机理，它们主要表现为&城&发展的延续。

The structure and stability of all possible isomers of C50X(X=SiH2, PH, S) were investigated by ab initio HF/3-21G calculations. The calculation results indicate that the preferred position for cycloaddition of SiH2, PH, and S on C50 is consistent, i.e. on the C3-C4 and C4-C4 sites of C50, and the resultant most stable cycloaddition isomers are [5,6]-closed and [5,5]-closed structures. The main driving force governing the stability of the C50X(X=SiH2, PH, S) isomers is the strain, or the conjugative effect, or the combination of strain and conjugative effect, depending on the addition positions and the types of the attacked C-C bonds.

用从头算HF/3-21G方法研究了C50的环加成衍生物C50X(X=SiH2， PH， S)所有可能的异构体的结构与稳定性，计算结果表明，SiH2基团、PH基团与S原子在C50上环加成的优先加成位置相同，都为C3-C4类键和C4-C4类键，并且相应形成[5，6]-闭环和[5，5]-闭环结构的最稳定异构体；决定C50X(X=SiH2，PH，S)各异构体稳定性的主要因素，因加成位置以及发生加成反应的C-C键的单双键类型的不同，可能是张力、共轭效应或者二者的共同作用。

In the end, the paper demonstrates the application of the model with two listed companies in China, Younger and Kelong. It makes some calculation based on the initial experts grading, and gets basic status of the two companies by the analysis of weights, relative importance and effect of each factor. The results from the model are not contradictious to those from professional credit rating companies, who usually evaluate firms through financial analysis and on-site investigation.
