In this thesis, terahertz transmission properties through three kinds of simple sub-wavelength metallic structures, including single sub-wavelength metallic circular hole, single sub-wavelength metallic slit and double sub-wavelength metallic slits, are experimentally investigated in the far field by using our own THz time-domain spectroscopy system and are theoretically analyzed. Conclusions are obtained as follows:(1) a single sub-wavelength metallic circular hole exhibits the same terahertz transmission properties as that of round metallic waveguide, which are influenced by the diameter of circular hole and the thickness of metal foil.

All the sub-plans are described by a group of general mathematic formulae. The computation of the sub- plan can be decomposed into two sub-problems by relaxing the constraint that production level at production period of a sub-plan must be more than zero. Based on the properties of an optimal solution, two polynomial algorithms are devised to solve sub-problems and reintegrate the relaxed constraint. Finally, a dynamic programming algorithm with complexity O(T^4) is developed to solve the global problem, where T is number of periods in planning horizon.

In order to analyze the reason for a flawed Iraqi identity, this article delaminates the internal identity of Iraq to two levels——national and sub-national, further distinguishes familial identity, religional identity and ethnic identity on the sub-national level, and studies the relations between national and sub-national identities with looking back at the momentous events in Iraqi history, consequently finds the different influences that various of sub-national identities react on the formation of Iraqi national identity and how the discriminative internal policy intensified sub-national identities, and then builds a theoretical framework with two dimensions from upwards and downwards to explain the reason for unshaped Iraqi national identity.

为了分析伊拉克国家认同没有形成的原因，文章将伊拉克内部认同在国家和次国家两个层次上进行划分，并进一步区分了次国家认同中的家族部落、宗教派系、族群这三个认同类型，然后以国家认同和次国家认同的关系为切入点，研究了伊拉克历史上的几个重大事件，发现了各次国家认同对国家认同的形成具有不同程度的影响，其中族群认同对国家认同形成的破坏作用最大；与此同时，伊拉克前政府歧视性的内部政策强化了各次国家认同，是造成伊拉克国家认同没有形成的另一个原因，从而从上、下两个维度解释伊拉克国家认同未形成原因的理论架构。
