Combined with the general solution for the above problems, the analytical solutions for crack tip fields with surfaces acted on the above three kinds of loads are obtained. These solutions offer theoretical basis to construct analytical elements for plastic analysis of crack.

The thesis resorts to the methods of deduction and counterevidence to demonstrate the defects of textualist and contextualist stylistics both theoretically and practically. Then it puts forward an analytical model, which incorporates them. Finally, by applying this model to the analysis of Andrew Marvell's To His Coy Mistress, William Blake's London and George Owell's A Hanging, this analytical model is proved to be able to avoid many drawbacks common with the previous stylistic studies.

文章首先用演绎和反证的方法，从理论和实践两方面指出了文本主义文体学和语境主义文体学的缺点，然后提出了一种有机结合这二者的综合分析模式，并用该模式分析了安德鲁·马韦尔的《致羞涩的情人》，威廉·布莱克的《伦敦》和乔治·欧维尔的《绞刑》等三篇作品。

Chapter six presents such new concepts as margin utility contribution force, profit-risk exchange rate, state-expectation-variance utility function, long-term expectation-variance utility curve and optimal portfolio expansion curve. The state-expectation-variance analytical method is developed from the expectation-variance analytical method. The changing rate of profit-risk exchange rate to state variable is used to define and distinguish the decreasing, constant and increasing relative risk aversion. A decomposition formula about the margin contribution force of holding wealth to state-expectation-variance utility function is displayed. The decomposition formula demonstrates that the contribution force of investors' holding wealth to their utility is composed of the pure contribution force of holding wealth and the investment contribution force bronght about through investment portfolio.

第六章提出了边际效用贡献力、收益—风险替换率、状态—期望—方差效用函数、长期期望—方差效用曲线、最优证券组合扩展线等新概念；把期望—方差分析方法发展成状态—期望—方差分析方法；用收益—风险替换率对状态变量ω的变化率来定义和区分递减、定常、递增相对风险厌恶；获得了持有财富对状态—期望—方差效用函数的边际贡献力的分解式，该分解公式表明投资者的持有财富对他的效用的贡献力由持有财富本身的纯贡献力和持有财富通过投资证券组合所产生的投资贡献力所组成。

Instead this paper focuses on the theoretical, analytical dimension and offers three theoretical, analytical explanations for the questions: 1 because the literary indigenization paradigm engenders a kind of antagonism between different historical narratives which is difficult to be weakened; 2 because in the identity politics strategic essentialism is ready to slide from a mere strategy to a form of de facto essentialism that provokes an essentialist backlash; 3 because the literary indigenization paradigm and the conflict caused by it, after all, involves state power.

因此本文另辟蹊径，从理论分析的角度提出三点解释：第一，由於文学的本土化典范是一种叙事的本土化典范，其相关的争论有如世界观的冲突；第二、由於认同政治∕文化斗争中的「策略的本质主义」与本质主义之间不易区分，即使是策略性的认同宣称，也容易引起本质主义色彩的对抗；第三，因为文学的本土化典范终究涉及国家权力。
