According to the existence results of general equilibrium problems and vector equilibrium problems have been studied more and more. Inspired and motivated by these research results, this paper is devoted to study systematically a class of equilibrium problems, which is unify and extension of a large number of known equilibrium problems and variational inequalities problems. The research is carried on from three aspects.Firstly, in finitely continuous topological spaces, we introduce four new types of the system of generalized vector quasi-equilibrium problems, and we derive some existence results of a solution for the system of generalized vector quasi-equilibrium problems via the maximal element theorems in product finitely continuous topological spaces.Secondly, in complete metric spaces, we provide the Ekeland variational principle to equilibrium problems with set-valued maps. And via the Ekeland variational principle, existence results for vector equilibrium problem with set-valued maps and the system of vector equilibrium problem with set-valued maps.
针对一般的均衡问题和向量均衡问题解的存在性,已有许多研究成果,受这些成果的启发,本文主要从理论上较为系统地研究了一类均衡问题,它统一和推广了许多已有的均衡问题和变分不等式问题,研究分有三个方面;首先,在有限连续拓扑空间中,我们提出了四类广义向量拟均衡系,并借助于有限连续拓扑空间中的极大元定理讨论了这四类均衡系问题的解的存在性问题,然后,在完备度量空间中,我们给出了关于集值均衡问题的Ekeland变分原理,并利用Ekeland变分原理分别讨论了集值向量均衡问题和集值向量均衡系问题的解的存在性。

So, he takes "Dance" as characteristic spacial consciousness in Chinese art and model of all Chinese Yijing , emphasizing that spacial consciousness and spacial representation of Chinese art just lie in "Seeing infinity in finitude, and returning to finitude from infinity". Only in such artistic space can the profound contents uncovered by artists (namely,"Tao", life rhythm,"real life","cosmic truth") be embodied, and can artistic creation reach its ultimate ideal and maximal achievement.
所以,他把"舞"理解为中国艺术的空间意识特征和一切中国艺术意境的典型,强调中国艺术的空间意识和空间表现就是"于有限中见到无限,又于无限中回归有限",只有在这样的艺术空间里,艺术家所要揭示的深刻内容(中国人所谓"道",亦即生命节奏、"真的生命"、"宇宙真际")才获得了具象化,艺术创造才达到了最后的理想和最高的成就。

To establish the constitutive equation of material, the metric tensor for stress , strain and their transformation equations between different configurations are derived, and basic theory of finite deformation as well as elasto-plastic deformation criterion are studied. By analyzing the applicability of different element models, four-node quadrilateral degenerated Mindlin isoparametric element is adopted because of its good versatility, and the element stiffness matrix is derived. The static implicit elasto-plastic finite element equation for complex skin stretch-forming is put forward based on Updated Langrange formulation.

The basic idea was to discrete the structure and find the load function according to the energy criterion of buckling and the principle of random displacement method. As the critical load is the minimum of the load function, a problem of frame buckling can be transformed into an optimization problem. Therefore, the critical load can be found through solving the optimization problem.
