分析几何学

On the basis of geometrical research,a new method that draws sufficiently with assistant vanishing point s is provided.

通过对量点法中灭点远超出图板的难点进行分析，从几何学角度研究，在30o~60o量点法的基础上，提出一种利用辅助灭点扩大对象表现区域的新方法。

The truths that conceptual analysis arrives at are thus apodictic, rather like the truths of geometry.

因此，概念分析得出的真理就像几何学的真理一样，是无可置疑的、必然的。

In accordance of dynamical analysis to asymmetric basin forming, it is restricted doubly by crust multi-layer rheological structure and regional geotectology background in the Lower Yangtze regional crust, especially in close relationship with action of C-layer (18-20km) in the Lower Yangtze region crust. After quantitative analysis of mutual relation between the basin geometrical feature and the crustal structure, a new way will be supplied to the research of Mesozoic-Cenozoic sedimentary basin evolution and the oil -gas exploration in the Lower Yangtze region.

在此基础上，对非对称盆地形成的动力学分析认为，它受下扬子地区地壳多层次流变结构及区域大地构造背景的双重制约，尤其与下扬子地区地壳C层(18-20Km)的活动密切有关，定量分析了盆地的几何学特征与地壳结构之间的相互关系，为下扬子地区中新生代沉积盆地演化的研究及其油气勘探提供了新的研究途径。

First, based on the analysis and comparison of wave breaker indices defined by geometric, kinetic as well as dynamic stability, which were verified by observation, the value α, which is equal to H/ by Miche' s result and may be modified by Goda' s results, is suggested as the wave breaking criteria. The applicable values of α for pure waves or wave-current co-existing field are given.

首先，基于对波浪破碎的几何学、运动学及动力学三种指标的分析比较和观测资料的验证，本文提出可以合田良实的结果为基础修正Miche的H／=α值，并提出了适用于纯波及波浪与水流共存时的临界α值。

The generalized fractal dimension model of openings perimeter in jointed rock mass is put forward. The relation between erecting parameters and generalized fraetal dimension of openings perimeter is analyzed. According to the fractal theory, the relation between overbreak as well as underbreak and generalized fractal dimension of openings perimeter is built.

块体理论是研究洞室超欠挖的重要工具，它是从拓扑几何学的角度来研究洞室中的关键块体，但关键块体与超挖块体之间存在区别，文中对超挖块体和关键块体之间的关系进行分析研究，应用块体理论和结构面网络模拟技术相结合的方法预测了洞室超挖块体的大小。

In this dissertation, sedimentology, historical geology, structural geology, geophysics, structural dynamics/geometric, plate structure etc were combined properly. Taking Jiyang depression as studying object, fault distribution of different periods was analyzed, and thus discussing their structural dynamics. Using tectonic subsidence history modeling and denudating relationship between hanging wall and foot wall in Mesozoic faults, fault activity characteristics were discussed.

本论文将沉积学、地史学、构造地质学、地球物理、构造几何学和运动学、板块构造等多学科有机的结合，以济阳坳陷为研究对象，采用各时期断裂分期配套，分析了不同构造运动时期济阳坳陷断层展布，进行构造运动学讨论；利用构造沉降史模拟与中生代断层上下盘剥蚀关系的恢复，探讨了中生代断裂活动的特征。

This database contains geometrical and molecular information that allows the classification and search of particular combinations of site characteristics, and answer questions, such as How many mononuclear zinc-containing sites are five coordinate with X-ray resolution better than 1.8 Angstroms? and then be able to visualize and manipulate the matching sites.

该数据库包含了从几何学到分子学的信息，借助这些信息可以对位点特性组合进行分类和检索，并且可以回答诸如有多少锌指结构包含在优于1.8埃X射线分析结果，随后便可以看到并对这些匹配位点进行操作。

Carnot wished "to free geometry from the hieroglyphics of analysis ".

Carnot希望&把几何学从分析学的画符样难懂的文字中解放出来。&

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
