在卸载和反向加载时，采用与骨架曲线相同的函数形式，并以前一次卸载开始点作为起点，以土体的极限应力水平作为渐近线，构造出土体动力本构模型的滞回曲线。

The first chapter gives the summary of basic theories of EOS for solids, including often-used thermodynamic theories and phenomenological expressions during the study progress of EOS along with the finite strain theory. Furthermore, from the view of solid-state theory the general expression of EOS of solids P =Pc+Pn is given, and the microcosmic mechanism of compression for solids, i.e., the interactive potential energy between atomics, is also analyzed, subsequently several different forms of cold energies and pressures are derived.

第一章，给出了物态方程的基本理论概要，总结了EOS研究中最常用的热力学理论和唯象关系式以及有限应变理论，并从固体理论角度给出了固体物态方程的一般形式P =Pc+Pn，分析了固体压缩的微观机理——原子间相互作用势，由此导出了几种不同形式的冷能和冷压。

Staphylococcus aureus Staphylococcus aureus with inhibition of 14 species (of the total strain of 87%).

Methods The clpE-deficient strain was constructed by LFH-PCR and identified by PCR and sequencing. The impact of clpE mutant on the virulence of S. pneumoniae was evaluated in a mouse model. In addition, we also studied the effect of clpE mutant on adherence and invasion of host cells. Real time RT-PCR was used to measure the mRNA expression levels of autolysin A, pneumococcal surface adhesion A, pneumolysin, pneumococcal surface protein A and neuraminidase The clpE gene was replaced completely by erm cassette.
