After descibing the concepts, definitionsand operation approaches of quantum group and SLq(2) Lie algebra, the physicalmeaning of quantum group particles is explained in the present thesis. The gaugeinvariance in SLq(2) gauge field and its thermodynamics model is considered basedon the idea of q-deformation. The zero energy gap equation and q-deformed energygap equation are derived under the assumption of q-quantization and semi-classical q-quantization, then the zero-temperature energy gap A(0,q) and crititical temperature〓 can be calculated from the q-energy gap equation.
在介绍了量子群和SLq(2)李代数的基本概念,定义和运算方法后,文中进一步阐述了量子群粒子的物理意义;在q变形思想基础上,本文研究了SLq(2)规范场及其热力学模型中的规范不变性质,并在q量子化和半经典q量子化的假设下导出了零能隙方程和q变形能隙方程;然后从q能隙方程计算了与零温度能隙△(0,q)和临界温度〓。

It is proved that the problem of determining whether there is a Hamiltonian path from a specified vertex s to another t on a given digraph can be reducible at polynomial time to the problem of constructing a minimum spanning flow in a two-terminal extended network Ns,t, with the unit capacity for all arcs.
在此基础上,利用网络最小生成流的概念提出了一个修正模型,并证明了无环最小生成流问题可以在多项式时间内转换为哈密顿圈问题。文中最后指出,这一新的模型为解决在有向图内构造哈密顿轨的有效算法提供了一个新的思路和方法。

A simple coded modulation technique, which is called "split-phase coded modulation", is studied in this thesis. Such a technique is especially suitable to be applied in a multi-antenna system. To have an insight into the possible transmit diversity benefits to the proposed scheme, here we consider the employment of multiple transmit antennas and a single receive antenna for the considered system.
本论文探讨一个简单的编码调变技术,我们称为「相位分离编码调变」,此编码调变技术特别适用於多天线系统,为了进一步了解这样的架构在「传送分集」上所造成可能的效益,在此论文中,我们假设传输端布署多重天线,但在接收端仅使用单一天线接收。

A highly in uential source of this suspicion is Barry Stroud, who in his article 'Transcendental Arguments' suggested that for any claim concerning the necessary condition S,"the sceptic can always very plausibly insist that it is enough we believe that S is true, or it looks for all the world as if it is, but that S needn'tactually be true"(Stroud 2000: 24).3 So, in the case of the problem of the external world, for example, the concern is that no argument can be constructed to show that there must actually be an external world, but just that there must appear to us to be one, or that we must believe there to be one.
斯特劳德在《先验论证》一文中指出,任何涉及必要条件S的断言都会受到怀疑论者这样的反驳:我们确实要相信S是真的,或者说在所有的世界都是这样,但是,S不需要真正地为真。所以,在外在世界问题上,并没有一个论证可以给出证明,说外在世界必须真正实际地存在,而我们只能说,必须有一个外在世界向我们显现,或我们必须相信有一个外在世界。

In the sense of Von Karman large displacement, the governing equation of nonlinear dynamic response of the clamped circular plates under impact of a mass is established by using the virtual displacement principle and Galerkin's method in this paper. The effect of coupling between the impact load and the displacement of. the circular plates is considered. The governing equation is solved by applying the time increment method and the singular perturbation theory, and the asymptotic solutions of nonlinear dyna...
