"Communications, leisure, living, product consist of city's fundamentalfunctions"(《Athens Charter》). With the development of society, tourism has becomean important function of city. City is the origination and destination of tounism byaccommodating the visitors. Because of the high efficience of transportation, perfectaccommodations, interesting amusement facilities and wonderful "human culturebackground", city becomes an important place which absorbs more and more people.Any landscape tourism zone or other places only depend on city that can formperfect receivirg systems. Tourism and amusement are different with the normalliving of citizen's, but all of these actions are under the base of fitting the high levelleisure wanted. City provides important carrier to deal with this contradict.Meanwhile, it becomes the bridge between tourism and city planning and UrbanDesign. Only expanding this research fields under city level that can take the maincontradict of"City Tourism." City Tourism is composed with some different loose trades.

雅典宪章》认为：&交通、游憩、居住、生产&构成城市四大功能，随着社会的发展，旅游服务已成为现代城市重要功能之一，城市是出入境和接待工作的必经之地，也是旅游的主要目的地和客源地，城市由于其便利的交通、完善的住宿餐饮、娱乐设施及良好的人文环境而成为重要的旅游吸引地之一，任何风景旅游区或其他旅游活动也只有依附于城市才能形成完善的接待服务体系，旅游者在城市中的旅游与游憩需求与居民日常生活虽有差异，但都是在满足基本要求基础上的高层次游憩与休闲活动，城市为解决上述矛盾提供了重要载体，也成为旅游业和城市规划与设计行业共同发展的桥梁，只有深入城市层面展开研究才能抓住旅游产业发展的主要矛盾。

This problem is also important and valuable in Nonlinear Optics. It will be very helpful to understand how the aberrations affect the course of three- wave mixing, such as the change of conversion efficiency, the distribution of intensity and phase.Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental waves aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.

首次从三维三波相互作用方程组推导得到了位相畸变光束倍频的小信号解；通过建立国防科学技术人学研究生院学位论文三维数值模型，编写相应仿真程序，首次得到了位相畸变光束倍频过程的大量计算结果，深入细致地研究了位相畸变光束经非线性光学频率变换后谐波的转换效率、光强分布、位相分布以及影响它们的各种因素；得出谐波的远场发散角和光斑二阶矩的变化规律会因为基波像差的不同而不同，但谐波的远场发散角明显地比相应基波的小的结论；得到了在走离效应和衍射效应等影响许多因素可以忽略的情况下，位相畸变传递到二次谐波的估算式；举例分析了KDP三倍频方案中，基波位相畸变对二次谐波和三次谐波的影响；实验工作中，用哈特曼一夏克传感器分别对IO64nm倍频过程和790飞秒超短脉冲倍频过程中的基波和谐波的位相分布进行了测量，给出了相应结果。

Went to meet Jude for quiet drink to talk about Flow some more and noticed a familiar besuited figure with knitting-pattern dark good looks sitting in a quiet corner having dinner: it was Magda's Jeremy.

跟茱儿见面，我们静静地喝东西，再继续深入讨论冥想的问题，注意到有一个仪表堂堂的熟悉身影，穿著针织的衣服，安静地坐在角落吃晚餐———是玛格达的杰里米。

In this dissertation,preparation and thermoelectric characterization of conventional silicon-based materials and devices have been studied, including amorphous silicon films, polycrystalline silicon germanium films and amorphous silicon thin-film-transistors. A novel MEMS-IC integration method based on porous silicon micromachining has been developed, which is used to fabricate resistive bolometers with a-Si and polySiGe films, and a-Si TFT-based room-temperature infrared detector pixels and 8×8 arrays with primary capability of thermal imaging have been reported for the first time.

The application of fair value in Chinese Accounting Standa rds is full of twists. Under development of global economic integration and international coordination of accounting,Chinese standards-making institutions has realized that avoidance of fair value will lead to the set back of accounting theory. Thus, Fair value accounting is widely and deeply researched. In February 2006,the Ministry of Finance issued the new Accounting Standards System. Fair value as measurement was written in basic standard and widely applied in specific standards.

在经济全球一体化和会计国际趋同发展的大环境下，我国准则制定机构清醒地认识到，对公允价值的回避是理论上的退步，于是对公允价值进行了广泛、深入的研究。2006年2月，我国财政部发布了由一个基本准则和38个具体准则组成的新会计准则体系，首次将公允价值作为一种计量属性写入基本准则中，并且在具体准则中大量地运用了公允价值。

The well-acknowledged difficulty of translation can be accounted for by vinous reasons,ranging from many internal factosrs to external ones,bm there is,among other things,an internal cause which we can not afford to ignore,I.e.,the objective interference of between the translator and the source language writer In the course of translation ,the translator,conditioned by many of his own elements,is unable to share thoroughly the thoughts, feelings,emotions and intentions of the original whier....

翻译难是一个众所周知的事实。难的原因有多种，涉及许多内在和外在诸因素，其中有一个不容忽视的成因是译者与原作者之间客观地存在着&心智距离&，即译者在语际传译过程中，受自身诸种内在因素的制约，不可能真正地深入到原作者的内心中去，与原作者同思维、共呼吸，与原作者的意旨彻底复合。当代西方流行的接受美学理论为这一现象作了很好的佐证。
