变构性

Ringel realized positive parts of semisimple Lie algebras in the framework of Ringel-Hall algebras. The main result of this thesis is to build a geometric and topological model over triangulated categories such as derived categories and stable module categories of repetitive algebras. We defines a Lie bracket by Euler characteristics of constructible subsets and thus realizes infinite dimensional Lie algebras of various types with non-degenerated bilinear form.

本文的主要结果是在导出范畴和重复代数的稳定模范畴等三角范畴水平上建立相应的几何-拓扑模型，并利用相应可构集的欧拉示性数定义了一个Hall代数的交换子乘法，从而在三角范畴水平上实现了一大类无限维李代数的整体构造，并且这类李代数本质上都具有非退化的不变双线性型。

In this paper, granite of BeiShan was chosen, experiment was made to research on the granite behavior in the effects of temperature , combining damage mechanics and viscoelastoplastic theory, tentative efforts were made in the coupling of thermal and stress as well as rheologic constitutive formula.

本文选择甘肃北山花岗岩作为研究对象，对花岗岩温度影响下的力学行为进行了初步的试验研究，结合损伤力学和粘弹塑性理论在热应力耦合和岩石蠕变本构方程方面进行了尝试性的工作。

The article, focusing on the thought orbit especially in the field of literature, emphasizing the inter-link between the changes of their thought, explaining the life choice of thought subject and taking the learning and thought idea of World Consciousness and World View as breakthrough points, depicts their social and moral bear and transcendality of their thought version. Contrasting their literary thoughts of organon and ontology with each other, the article explains the central role played by "tragedy" in their thought structure and homorganic and interdynamic relations between their best but last aesthetic "tragedy" and life "tragedy".

本文以描述王国维、鲁迅二人的思想轨迹为中心，其中又以揭示二人思想、诗学迁变的内在链接为描述重点，兼及思想主体的生命选择，以学术、思想的&天下意识&与&天下观&为切入点，凸显二者的社会、道德承担和思想眼界的超越性，对比二人文学思想之工具论与本体论暨&无用之用&与&善撄人心&、&境界&与&摩罗诗力&，解说&悲剧&在二者思想构造中的中心意义，阐发这种臻于至境的美学&悲剧&与二人臻于绝境的生命&悲剧&的同构与互动关系。

RESULTS: Pathological diagnosis: hamartomatous polyp in the recta, but no besides malignant melanoma or blue nevus, suggesting to extend removal and close follow-up.

结果：病理诊断为直肠错构瘤性息肉合并大量黑色素细胞，不除外恶性黑色素瘤或蓝痣基础上恶变，建议扩大切除，密切随诊。
