The research of industrial stucture adjustment and upgrading in the new period: Based on the case of Nanjing ABSTRACT As the important contents of the subject of not only economy, but also economic geography, the industrial structure has great significance to the regional economic and social development. The adjustment and upgrading of industrial structure has the dynamic indissolubility without ceasing based on the absolute advancing of market demand without end, and the forever inevitability of the capital chasing profit.

新时期产业结构调整与升级研究—基于南京的实证产业结构不仅是经济学也是经济地理学研究的重要内容，产业结构的变迁对一个区域的经济发展和社。。。

In the wake of diversity of social economics activities, the application and rights and privileges of real estate also become more intricateness. If people explore the reason of conflict and disposal process just at the point of normative abstract content and applicable, it will always be unable to gain the ideal result. As to the dispute parties concerned, beside the different interpretation of the law and the fact, how to properly solve the problem is more important than the legal action.

随著社会经济活动的变化，对於不动产的使用形态与权利类型也日益复杂，如果探讨纷争发生的原因及其处理方式时，仅著眼於规范的抽象内容与如何适用，往往比较不能得到想要的结果，因为就纷争当事人而言，除了对於法律规范与事实之间的认知有所不同外，更重要的是如何妥善解决问题会比如何适用法律来得重要。

If it is feasible, the closed noninteractive literature-based KDD process can be used to prove the legitimacy of the open discovery process. This system also deals with "Title" and "Abstract" respectively in the light of Swanson"s method and retrieves the correct "B" word between the start literature"A" and the target literature"C.

系统采用的是Swanson教授本人的闭合式知识发现算法，同样对标题和摘要都进行了处理，结果发现用标题计算仅能求得部分中间词，而用摘要计算可以求得几乎所有期望得到的中间词，可见此算法处理摘要的效果优于处理标题。

The researches in this paper are based on the abstract theoretic models which are more accordant with the reality of the electric power system than the classical Cournot model. The results will provide references for electric power producers to make optimal output decision.

本文的研究是建立在高度抽象的理论模型基础上的，所建的模型比经典Cournot模型更复杂也更贴近电力市场运行的实际情况，其结果可以为实际电力系统的政策制定者提供较好的参考作用。

ABSTRACT The researches of this thesis are carried out around the development of high performance machine tool spindle permanent magnet synchronous motor and its drive system. Five parts are included: First of all, concerning the operating characteristics of the machine tool spindle drive system, the optimum current control strategies of spindle PMSM are determined; The design rules of spindle PMSM's key parameters are summarized, based on the study on the influences of the design parameters on the performances of the PMSM operating at different current control strategies; The practical methods to improve the flux-weakening ability of the PMSM are presented; Based on the analysis and comparison of the operating performances of PMSM with different rotor structures, a novel PMSM rotor structure, which is of excellent mechanical performance, suitable for fluxweakening operation and can improve the torque output capacity in the same time, is presented.

本文围绕高性能机床主轴永磁同步电动机及其传动系统的设计研究展开，所做工作主要包括五部分：首先，确定了主轴永磁同步电动机定子电流的最优控制策略；通过对不同控制策略下主要设计参数对主轴永磁同步电动机性能影响的计算研究，总结了参数设计规律；提出了永磁同步电动机弱磁扩速的实用措施；在分析比较不同转子磁路结构电机的性能，尤其是弱磁扩速能力的基础上，提出了一种机械性能优越，易于弱磁扩速，同时能保证电机恒转矩运行时的转矩输出能力的新型转子磁路结构。

They endeavour to prove that the ancient charter...were nothing more than a re-affirmance of the still more ancient standing law of the kingdom.... In the famous law...called the Petition of Right, the parliament says to the king,"Your subjects have inherited this freedom," claiming their franchises not on abstract principles "as the rights of men," but as the rights of Englishmen, and as a patrimony derived from their forefathers.

他们竭力在说明这份古老的宪章···不外乎就是王国的更古老的法律的重新确立···在这份众所周知的法律中···一种叫做请愿的权利，国会对国王说："你的臣民已经继承了这种自由"，这宣称了他们的权利不是建于更抽象的"人的权利"原则之上，而是"英国人的权利"，是从他们先辈那里继承的遗产。

He therefore criticized Leibniz, saying the main disadvantage of pictography – in comparison to alphabetical writing – was that the essence of the former is bound to the "sensuous-concrete", while only the latter manages to capture the abstract and the formal.

因此他批评莱布尼兹，说比起拼音书写，象形文字的短处是它被'感官-实形'所困，只有拼音文字才能捕捉抽象和形式。

Research on the Development Issue of Chinese cocoon and silk industry Abstract The cocoon and silk industry is our country's traditional industry, as "the achievement industry", it has made great contributions for the national economy and occupied the monopoly status in the international market. So far, there are 20 million farmer families which are dealing with planting mulberry and sericiculture, one million silk workers.

茧丝绸业是我国的传统产业，是为国民经济发展做出过重大贡献的"功勋产业"，是在国际市场上处于垄断地位的优势产业。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
