( 2 ) because of different initial density of samples were always used in shock wave experimental measurement by different researchers , the hugoniot data always shows contradiction sometimes . this is inconvenience for the advanced analysis and application of hugoniot data . so , it is very necessary and important to modify the hugoniot data for porosity ( 2 )在hugoniot线的实验测量中，由于客观条件的限制，不同的人所使用的样品的初始密度不同，这使所得的hugoniot数据的分散性较大，也给hugoniot数据的分析、应用带来很大不便，甚至存在一些疑问，这就影响到数据的物理解释。
Firstly , i expound the important meaning of the monitor of big dam safety and the development and the present condition of big dam deformation analysis . secondly i generalize the past application study for fem , establish the displacement conclusive model of dam to explain physics reason from the water pressure , temperature , time limited efficacy three aspects analyze 然后，在总结前人对有限元的应用研究的基础上，重点就大坝的变形和变形原因之间的物理解释，从水压、温度、时效三个方面分析，建立了基于有限元大坝形变分析的确定性模型。
In the dissertation , an in - depth study is carried out by the author by synthesizing multi - disciplinary knowledge on the following topics : the abstraction of weak spectral signal , the optimal pathlength measurement condition , the optimization of regression method , the enhancement of multivariate calibration model robustness and the physical explanation of measurement results are studied 本论文综合多学科的知识深入研究了从重叠复杂的光谱中提取微弱的化学成份信息的方法，最佳测量条件的设计，建模方法的优化，校正模型稳健性的提高以及测量结果的物理解释等关键技术基础问题。
This paper reviews the history of research of long - range dependence and self - similarity in data network traffic , introduces the related concepts and discusses the physical interpretation of long - range dependence and self - similarity along with fractional brownian motion . finally , a method for generating fractional brownian motion random series is analyzed 本文将介绍长程依赖和自相似在计算机网络研究中的历史状况，相关数学概念，给出了基于分数布朗运动的计算机网络业务流呈现长程依赖和自相似属性的数学和物理解释，讨论分析分数布朗运动随机序列生成方法。
