优势原理

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。
