The simulation result shows the collection efficiency of TIR lens model is 67% when the angle of light is confined within 15°. And the uniformity on observation screen is improved in some degree. The optimal design of TIR lens further provides the development space of LED micro-projection display system.4 On the base of the theory research and the model simulation, four projection display systems which have LCOS as micro-display panel and which combine different optical devise for UHP and LED light source respectively are proposed in this dissertation. And the quality of projection display system is evaluated by thesimulation outcome.

Finally, the grafting polymerization of textile materials initiated by microwave low temperature plasma was conducted. Knitted cotton fabric was grafted by AMPS first, then knitted cotton and terylene/cotton fabrics were grafted with AMPS/NIPA dualistic monomers respectively. By means of grafting polymerization, the P dualisticintelligent hydrogel was added to textile.The influences of the factors on add-on, such as treatment time and power of plasma, concentrations of crosslinking agent and total monomers, proportion of AMPS, polymerizing temperature and time etc, was studied fully. The optimal conditions of grafting polymerization initiated by microwave low temperature plasma were determined by orthogonal design, variance analysis and mathematical statistics method so as to analyze the main influencing factors. Then swelling/deswelling kinetics, temperature-sensitivity and pH-sensitivity of grafted textile were studied. The performance indexes of hydrostatic pressure, moisture permeability and bursting strength of the knitted cotton and terylene/cotton fabrics before and after grafting were compared and evaluated synthetically.

According to the information grasped by author,there lacks the systematic and specialstudy on diplomatic policies of modern Egypt weather in international or in internal academicstudy.Moreover,the study of diplomatic policies of Nasser's age is still in the initial stage.However,the study of Nasser as the leader of nonalignment movement gives us a deep impression,in which of course did not lack the study on Nasser's diplomatic policies,but as a whole therelacks the systematic study.

据笔者掌握的情况，国内学术界尚缺乏对埃及外交进行系统而专门的研究，而对纳赛尔时代埃及外交的研究也处在一种起步的阶段，与这种情况形成对比的倒是对纳赛尔作为不结盟运动领袖人物的研究，使人们对纳赛尔保持着深刻的印象，这当中固然不乏对纳赛尔外交政策的论说，但总体上看仍缺乏较为系统的研究。
