Using mordern physical chemistry techniques (such as XRD、 TG-DTA、 IR、 XPS and 〓Xe-NMR)、 chemical adsorption techniques (NH〓-TPD、 H〓-TPD、 TPO、 TPR etc.) and pulse flow microreaction of n-hexane、 methylcyclopentene and n-hexane containing 0.2ppm thiophene, we studied mainly the following three points:(1). the changes occured during the calcination pretreatment of Pt ammine complex supported on β and L zeolites;(2). the effect of structure and acidity-basicity of zeolite on the dispersion and electron state of Pt particles; and (3). the influence of second metal component on the reactivity of nhexane aromatization and sulphur-resistance of Pt/L zeolite catalyst. Several interesting and valuable results are obtained and summerized as follows

In chapter three, the dynamics of a driven spin-boson model is studied by means of the perturbation approach based on an unitary transformation. Analytical expressions for the population difference and the coherence of the two state system are obtained.

在第三章中，采用基于幺正变换的微扰方法，我们研究了驱动spin-boson模型的动力学，得到了在微波驱动下二能级系统的粒子数反转和相干性的解析表达式。

The relationship among three ensemble s (microcanonical ensemble ,canonical ensemble ,and grand canonical ensemble ) was discussed by means of derivation of distribution function,calculation of partition function,clarification of the basic thermodynamics as well as the fluctuations of particles in order to get profound cognition of these three ensemble s.

从三则系综(微正则系综、正则系综和巨正则系综)分布函数的推导，配分函数的计算，基本热力学量的表达及能量、粒子数的涨落等方面来讨论三则系综之间的关系，以便更深刻地认识三则系综之间的关系、灵活运用三则系综来解决实际问题。

Due to the low viscosities of inversemicroemulsions, our approach is suitable for the direct impregnation of porous SiC materials with well-defined ceria nanoparticles.

由于反相微乳剂的粘度低，我们的方法适合用轮廓清晰的氧化铈纳米粒子对多孔碳化硅材料进行直接渗透。
