ABSTRACT The research of this thesis is supported by China National Natural Science Foundation. The static and dynamic behaviour of slabs on foundation and doweled slabs of concrete pavement, identification and comparison of static and dynamic parameters are studied emphatically in this paper.

本文在国家自然科学基金项目资助下开展工作，着重研究了混凝土地基板与接缝板的静、动力特性及静、动力参数的识别与比较，主要包括以下几个方面的具有特色的内容。

In the last chapter, according to the requirement of the 4 mechanisms^(efficiency, evaluation, control and exhorting) in the

其次，我们必须建立武器装备的全系统、全寿命项目管理模式，以效益为原则，以科学和制度化的管理为基础，充分利用社会的经济、技术和设施设备，包括最主要的人力资源，利用商业化的采办方法，在满足军方需求的情况下，大量地采购或扩大采购军选民用产品，利用经济和法律的手段，调整工业结构布局和产品结构，为市场经济发展提供良好的外部环境。

The thesis includes five parts as followed:(1) In the first part ,we divide the change of Henan provincial inhabitants consuming structure into two steps to research that is from year 1952 to 1978 and year 1979 to 2001.Also we use statistics to carry out analysis of eating, wearing, expensing and living items which preliminary reveal changing rule of our provincial consuming structure.

本文的主要内容有以下五个部分：(1)在本文的第一部分，我们将河南省城乡居民消费结构的变化情况分为1952-1978年、1979-2001年两个阶段进行研究，并分别应用统计数据对吃、穿、用、住等项目的变化进行了分析，初步揭示了我省居民消费结构变化的规律。

At first,it expounds the related theory of financial evaluation .

本文主要对项目评估中的财务评估进行探讨。

The main creating aspects are finding and clarify such a fundamental physical process that the grain boundaries emit vacancies under compressive stress to induce solute non-equilibrium grain boundary dilution and absorb vacancies under tensile stress to induce non-equilibrium grain boundary segregation, formulizing the structural equations and the composition equations in force equilibrium in grain bounary region to describe this physical processes and the kinetic equations for non-equilibrium grain boundary segregation under tensile stress, calculating the modulus in grain boundary region from the expermental data of grain bounday segregation using the structure and coposition equations and calculating the diffusion coefficients of vacancy-solute atom complexes using the kinetic equation simulating the experimental results of grain boundary segregation.

本项目的主要创新点是，发现并阐明了弹性应力场作用下空位与晶界交互作用的基本物理过程：在张应力作用下，晶界会吸收空位，引起溶质非平衡晶界偏聚；压应力作用下，晶界会发射空位，引起非平衡晶界贫化。建立了描述此物理过程的晶界区力学平衡的结构方程和成分方程；？建立了张应力引起的非平衡晶界偏聚动力学方程？；用晶界区力学平衡的结构方程和成分方程？，首次通过实验测量计算出多晶材料晶界区的弹性模量；通过建立的动力学方程模拟实验结果，首次获得溶质原子－空位形成的复合体的扩散系数。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
