Lasers characteristic as a shock wave drive and the advantages of KrF laser are explained. Finally, the progress at home and abroad is enumerated.In chapter two, the basic principle of the EOS study is introduced. Specially, the impedance mismatch effect of the double-layer flyer is mentioned here. It is the primary theoretical basis of this paper.In chapter three, a one-dimension, three-temperature hydrodynamic code HYADES is introduced briefly. it is used to make a qualitative analysis about how the thickness of ablator affect the flyer velocities and stability.In chapter four, the experimental setup is described.
第一章为绪论部分,简要总结了状态方程研究的历史,激光作为冲击波驱动源的特点和KrF激光的优势,以及国内外的进展情况;第二章是本工作的理论基础,讨论了冲击波物理和雨贡纽曲线测量的基本原理和方法,重点介绍了激光飞片法的特点、关键要素和双层飞片的阻抗失配效应,鉴于KrF激光短波长和长脉宽的特点,我们拟对双层飞片的特性展丌研究工作,为实测状态方程做好准备;第三章简单介绍了一维三温流体力学数值模拟程序Hyades并运用它进行了若干状态方程实验的计算和设计,进行了烧蚀层厚度对飞片速度、稳定性的影响的定性分析;第四章是实验平台描述部分,介绍了光束平滑化技术,靶的制作,条纹相机的原理和使用,系统同步控制以及光学记录速度干涉仪系统的简单原理和构成。

Tooby and Cosmides proposed some rules about functional analysis:①functional analysis should be expressed in adaptationist terms,②a set of phenotypic properties is not an adaptation if it is transient, varying from individual to individual,③adaptations should be distinguished from their expression (which may vary from context to context),④a set of phenotypic properties is not an adaptation if it was absent in the environment of evolutionary adaptedness,⑤a set of phenotypic properties is not an adaptation if it did not solve an adaptive problem in the environment of evolutionary adaptedness.
图比和考斯米戴丝提出了功能分析的原则:①功能分析应该用适应的术语来表达;②一系列表现型的特点如果是暂时的,在不同的个体身上发生变化,它并非是一种适应;③适应应该与它们的表现(在不同的情景中可能发生变化)区分开;④一系列表现型的特点如果在进化适应性环境中不存在,则不是一种适应;⑤一系列表现型的特点如果不能解决进化适应性环境中的一种适应性的问题,也不是一种适应。

Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.
菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别,特别是花器官发生特点差异尤为显著,如菖蒲属花器官发生过程中,没有苞片原基,也不存在任何形式的复合原基,花被与雄蕊原基均以单向性方式发生,雌蕊由3心皮发育而成,具有"盾状心皮"的特点等,黑三棱属则有苞片原基发生,且苞片原基与雌花原基起源于共同的复合结构,雄花的花被原基和雄蕊原基均以螺旋状方式发生,雌蕊由单心皮发育而成,未发现有2或3个心皮原基或其痕迹的现象,体现出"囊状心皮"的特点。

The main work and innovation1 In general , a image compression method has different effect to different image . Some are fit for image which has much high frequency . Some are fit for image which has much low frequency .This paper analysis the applicability of fractal algorithm . In this dissertation , an improved algorithum is given . The basic algorithum without eight change and the joint use of quantitative coding , The compression ratio and PSNR can be adjusted , and it can get more quickly speed of coding .2 To a group of exact fractal code , the decoding image can be any resolution .With this characteristic ,choose the proper domain block and range block,this paper get an algorithum which can get higher decoding PSNR and speed than the basic fractal algorithum.3 Give a new method to calculate the scale factor . The calculation of basic algorithum is complex and enormous . The factor of scale is an important variable of the basic algorithm. Now there are two methods to calculate the factor of scale .A new method was given to calculate the factor of scale. The calculation load and complexity are reduced by the new method. Compared with the basic algorithm , the method can reduce coding time.4 The basic fractal algorithum is based on the Collage theorem and contraction mapping theorem . A mathematic model based on basic fractal algorithum is given .
本文的主要工作及创新点主要包括以下几点:1一般情况下,一种图像压缩的方法对不同特点的图像,压缩效果会有所不同,本文利用分形压缩编码对不同特点的图像进行编码,分析了分形编码对不同图像的编码适用性,利用去掉8种变换的分形编码算法与简单的均匀量化编码方案相结合,得到了一种可以调节压缩比与解码质量的分形编码方案,该提高编码速度6倍以上。2分形编码的特点之一是分形解码的分辨率无关性,即对于一组分形编码可以将其解码到任意分辨率下,本文利用分形编码的这一特点,结合不同的量化编码方案,选择合适的定义域块与值域块及适当的编解码分辨率,得到了一种提高解码质量,编码速度提高12倍以上的加速算法。3比例因子是基本分形算法中的一个重要变量,目前有两种计算比例因子的方法,文中给出了一种新的求比例因子的方法,该方法简化了求比例因子的计算,从整体上减小了基本分形算法的计算量,简化了算法4分形压缩的数学基础是不动点定理与拼贴定理,本文根据基本的自动分形编码方法,建立数学模型对其进行推导,得到了用普通数学的极限理论解释分形编码的数学表达式,从而对由基本分形编码得到的解码图像中的像素点的值给出了确定的表达式。

One of his online essays,他的一个网上杂文, The Origins of the Overclass 起源的overclass , attempted to show "why the richest 1 percent have exploded ahead since 1975, with the help of the New Right, Corporate America and, surprisingly, the CIA." In the essay he argues that Richard Mellon Scaife ran Forum World Features, a foreign news service used as a front to disseminate CIA propaganda around the world.
