Secondly, by introducing the generators of the infinitesimal transformations of Jourdain, the Noether′s theorem for the above nonholonomic systems of variable mass in event space has been obtained, which is based upon the invariance of the differential variational principle under the infinitesimal transformations of group.

这一成果揭示了力学系统的守恒量和其内在的对称性的关系，极大地推动了力学、物理学的发展。在近20年来，国内外的许多学者相继对Noether定理做了多方面的推广，不但用Hamilton作用量而且用微分变分原理研究完整和非完整系统的守恒律。

The former three chapters are about theoretical research, and the forth chapter is about empirical research. The theoretical research part generalizes the theoretical basis, theoretical model and the concept of city competitiveness both at home and abroad. According to these theories, the paper introduces the complete and explicit definition of city competitiveness and brings in a new city competitiveness model .The paper emphasizes on empirical research using the data in 2004 as sample, whose objects are ten big cities:Guangzhou, Shenzhen, Tianjin, Shenyang, Dalian, Nanjing, Hangzhou, Wuhan, Chongqing and Chengdu. Firstly, on the basis of mean square deviation method, it finds out both the scores of integrated competitiveness of cities and other factors, based on that analyze the relationship between them. And then the paper computes the scores of competitiveness of cities above by principal component analysis and sorts out them for assessment.

理论研究部分主要是概括的叙述了城市竞争力研究的理论基础和理论模型及国内外城市竞争力的概念，在此基础之上对城市竞争力给出了完整明确的定义，并提出了新的城市竞争力模型；全文的重点在实证分析部分，实证分析是以广州、深圳、天津、沈阳、大连、南京、杭州、武汉、重庆、成都10个城市为研究对象，以其2004年的数据为样本，首先用均方差的方法计算各城市综合竞争力与各要素竞争力的得分，以此来分析综合竞争力与各要素竞争力之间的关系，然后采用因子分析的方法计算2004年各城市综合竞争力的得分并给出排序进行评价。
