构造上的

Second, in the viewpoint of crypto analysis, the practical requirement for the cryptographic function is to construct the function that can resist all the known crypto analysis and attacks. In advanced, the main cryptographic properties are compared, and the relation among these cryptographic properties is analyzed, including the trade-off ones. Get the conclusion that the construction of cryptographic Boolean function is to find out the proper Boolean function in the whole vector space under the restriction of several cryptographic properties required for the security system.

然后本文从密码分析的角度，讨论了密码函数的实际需求，即构造能够抵抗已有密码分析与攻击的布尔函数；分析了布尔函数的主要的密码学性质，并比较了这些性质之间的相互关系，包括制约的关系；得出了构造布尔函数的实质的结论，即在向量空间中构造全体布尔函数，以所需的若干密码学性质作为限制条件，用有限域上的多项式、Walsh谱、Hadamard矩阵等数学工具找出适当的布尔函数用于加密体制的设计。

It is an intracontinental deformation system resulting from the structural stress caused by the collisions of the Huaiyu terrane moving westwards and the Cathaysia block moving northwestwards.

江南古陆与华夏古陆拼接带北西侧前震旦纪地层中存在着近东西向褶皱叠加在早期近南北向褶皱上的现象，这是怀玉地块向西拼贴、华夏古陆向北西碰撞拼接过程中构造应力向陆内传递时形成的构造变形系统。

Hybrid diwa-type orogeny which is the most common is composed of the former two types in space or in time.

在壳体构造理论下，笔者将地洼型造山运动定义为后地台阶段的构造—岩浆活化过程中各种地质作用的总称，并根据其动力来源和壳体运动方式，将地洼型造山运动划分为汇聚式、离散式和混合式，其中混合式是前两类型在时间或空间上的交替，最为常见。

On the basis of a detailed structural analysis, a succession of tectonic evolution since the Paleozoic has been set up .

在多尺度、多层次构造解析的基础上，建立了该区自古生代以来的构造演化序列。

Section two elaborates the structure of a simple model on static yield curve of zero-coupon bond. According to the difference of constitution principle, the dissertation divides the numerous static models into direct ones and indirect ones. On the basis of setting forth the different constitution thoughts of two methods, it compares the merits, shortcomings, and the application scopes of the two methods. Spline model is the most common indirect method, and is the study emphasis of this section, especially its three key approaches that are defining the rank of function, the subinterval number to be divided, and knot of each subinterval, which are fully elaborated in the dissertation.

第二节阐述了现行静态零息票债券收益率曲线简单模型的构造，根据构造原理的不同，论文把众多静态模型划分为直接法和间接法两大类，在简述两种方法各自不同的构造思想的基础上，对两种方法的优缺点及适应范围进行了比较；分段样条函数模型作为最常用的间接法，是本节研究的重点，尤其是对它的三个关键环节：确定函数的阶数、确定所分的段数、确定各段的分解点，论文更是给予了充分的论述。

There are massive salt dome s of great thickness,which ranges from several dozen meters to 3,700 meters,in pre-salt Carboniferous carbonate reservoirs of the Pre-Caspian Basin.

由于盐丘和围岩间存在巨大的速度差异，因此导致盐体本身和下伏地层在常规地震资料中出现反射品质降低、构造失真、畸变(如盐下石炭系目的层地震反射层在盐丘部位出现构造上拉现象)，消除盐层的影响是含盐油气盆地勘探的重要课题。

Yizheng movement, Wubao movement and Sanduo movement happened ordinally in Gaoyou depression and then regional unconformity formed. According to the feature of unconformity and stockwerke, the sedimentary cover could be compartmentalized as upper, middle and subjacent stockwerke. Fault activity is different because of different intensity of structural movement.

高邮凹陷先后经历了仪征运动、吴堡运动和三垛运动等几大规模构造运动，形成了区域性不整合面，依据不整合及其分隔的构造层的结构特点，可将高邮凹陷的沉积盖层划分为上、中、下三个构造层。

Secondly, under the guideline of earth system science, we put forward a theory of universal tectonics,initially build the theoreticl system based on studying the history of geotectonics and present level of earth science.

以地球系统科学为指导思想，在对大地构造学发展史和地球科学现状总结、分析和研究的基础上，提出了统一构造理论的新观点和理论基础，初步建立了理论体系框架。

Moreover, the seismotectonic belts were applied in seismic risk region analysis to discuss the relationship among SB, SRR and precursory anomaly.

在此基础上，具体地把地震构造带的概念应用于地震危险区分析之中，探讨了地震危险区及地震前兆异常与地震构造带的关系。

In the work area, the Jurassic system Shaximiao gas reservoir is dominated by distributaries channel sand, mouth bar sand of river-lake delta depositianal system and fracture. The lateral change of the reservoir is fast, distribution rule of the gas reservoir is complex in vertical and horizontal direction. The gas reservoir is dominated by lithology and tectonic action etc. It is a lithological gas reservoir base of structural setting.

工区侏罗系沙溪庙组气藏受河流－湖泊三角洲沉积体系下的分流河道、河口坝砂体及裂缝综合控制，储层横向变化大，气藏纵横向分布规律复杂，受岩性、构造多种因素综合控制，为构造背景上的岩性气藏。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
