with the focus on the rivalry between idea and writing technique in eileen chang studies,this thesis studies chang's feminist writings so as to probe into the divergence between scholars home and abroad upon the relationship between idea and technique: most scholars in mainland pay much attention to idea and tend to incorporate chang's inferior position of the "second sex" as a supplement into the feminist literary tradition of chinese new literature;besides emphasizing technique,overseas chinese scholars associate technique with idea by interpreting chang's feminist writings as subversive acts to undermine chinese androcentric literary tradition.

着眼于张爱玲研究中的意识与技巧之争，从张爱玲的女性写作切入，探讨海内外学者在意识与技巧关系问题上的差异：大陆学者多是就意识而谈意识，将张爱玲甘于&第二性&弱者的女性立场，以&补充&的姿态&纳入&中国新文学女性文学传统；海外华人学者在重视技巧的同时，将技巧联系意识，借张爱玲的女性写作技巧对中国男性主流文学传统进行破坏和颠覆。

分子进化分析就是利用分子数据来研究进化问题。地球上呈现的生物多样性则是突变和自然选择的产物，是生物进化的结果。生物进化的过程包含有两个面：基因的长期进化和遗传多样性，也就是通常意义上的大进化和小进化。该项目就是以两个不同的实验——即&蛱蝶科各亚科间分歧时间的估计&和&青藏高原垫状点地梅的空间遗传结构分析&——分别探讨了分子进化分析在大小进化两个方面的应用。

经与解析方法、积分方程等其他方法的计算结果对比表明，交错网格有限差分法结合散度校正和不完全乔累斯基分解预处理的双共轭梯度迭代方法进行正演计算，速度快、精度高、结果稳定，能适应三维复杂介质的数值模拟，为三维电磁反演奠定了基础。

The concrete work include: First, we consult a lot of herbarium specimen from PE, NAS, IFP and XJA etc.; Second, we collect more than 100 species of Brassicaceae from Xinjiang, Jilin and Shandong; Third, we study the phylogeny of Brassicaceae from China to approach some divergence on the tribe, genera and species of Brassicaceae using many ways including morphology, micromorphology and molecular systematics, furthermore, estimate the significance of every index.

2确定了两种模式植物-拟南芥与盐芥的系统学位置和系统学关系，认为两者分别归于拟南芥属和盐芥属，其亲缘关系较远，拟南芥属靠近须弥芥属、荠属、亚麻荠属、旗杆芥属、无苞芥属、糖芥属以及垂果南芥等，而盐芥属靠近山嵛菜属和沟子荠属，对于它们的深入认识，为两种模式植物在进化领域研究物种抗逆适应与趋异分化提供了一个不可多得的比较模式系统，以及更多可供比较的物种，具有重要的应用价值。
