进展速度

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。

The good news is that, at the present rate of progress, reliable missile defence is only 50 years away.

好消息是，目前的进展速度，可靠的导弹防御系统是只有50年的距离。

At the present rate of progress some centuries will be needed for the great work.

目前的进展速度有些世纪将需要伟大的工作。

The combined training effort of a native-speaking and a local English language trainer's assistant will improve the speed of progress for young learners by creating a bilingual learning environment.

由一个本土母语和一名当地的英语教练的助理将改善进展速度为青少年学生创造一个双语的学习环境。

I hope to have a normal speed.

我希望我们能有个正常的进展速度。

"While a lot studies HAs assessed alcohol consumption and cognitive function in the elderly, the is the first absorbing to see at how alcohol consumption affects the rate of progression of mild cognitive impairment to dementia," absorbing authors Dr. Vincenzo Solfrizzi and Dr. Francesco Panza, from the University of Bari in Italy, say in a statement.

研究报告撰写者、意大利ITALY巴里Univeisity的温森佐·索尔弗里兹博士和弗朗西斯科·潘萨博士在一份声明中说："此前有很多研究对老年人饮酒与认知功能间的联系停止过探讨，而此项研究则首次对饮酒会咋样阻碍轻度认知损害向痴呆症的进展速度停止了探究。"

The results showed that it would gain higher sustainable genetic respons and lower inbreeding rate when implementing BLUP selection in larger population. When the sire-dam ratio was too low, it would not only decrease the genetic response, but also increase the inbreeding rate. To gain higher genetic progress and acceptable inbreeding rate, it should keep enough large population size and feasible sire-dam ratio in practice.

结果表明，扩大育种群规模不仅可以获得更大的持续进展，同时还可有效缓解近交系数的过快上升；育种群中公畜比例过低时，不仅会降低遗传进展，群体近交系数的上升速度也会加快，实际中应保证育种群具有一定的规模和适宜的公母比例。

But this impressive pace of progress will slow if we don't recommit to funding cancer research.

如果我们不重新提出癌症研究资助的问题，这种惊人的进展速度将减缓。

那个倾斜的信封呈现了印刷的进展速度。

But the mild sanctions imposed so far are not working, and now the technological clock in Natanz is outrunning the diplomatic clock at the United Nations.

但迄今为止实施的温和制裁均不奏效，在纳兹坦技术上的进展速度超过在联合国外交上的进展速度。

I can not make it blossom and suits me
