This thesis mainly discusses numerical experiment of the error expansion and extrapolation theory of extensional rannacher - turek nonconforming element . comparing to the other extensively used element , we clearly see which element is more effective 本文主要讨论了特征值问题拓广rannacher - turek非协调元的误差展开与外推的数值实验结果，与其它几种广泛使用的有限元比较，我们能清楚的看到哪个有限元更有效。
The system is made up of control center and extensional control computer . the system is developed on the platform of visual c + + and the software model is made . the software system is divided into several modules , which are independent and interconnected 本文制定了系统模型的设计方法，系统由主控中心和分控计算机组成，选用vc作为开发平台而研制，并给出了系统的软件模型，将整个系统分为相对独立又相互联系的几个模块。
In the end , this thesis also devises numerical experiment for problems with small perturbation on its boundary strip . result shows that rannacher - turek element becomes exceptionally unstable . on the contary , extensional rannacher - turek element is more reliable 最后，本文又对所处理区域的边界带有小扰动的问题，进行了数值实验，实验结果表明rannacher ? turek元变得异常不稳定，而相比之下拓广的rannacher ? turek元更可靠。
Furthermore , shear type is simple shear - dominated at the early stage by analysis of wk from the method of polar mohr and pure shear component increases at the late stage by the methods of ecc . much synthetic extensional crenulation cleavage ecc is found in mylonitic rocks zone 不同方法求得运动学涡度wk介于0 . 453 ? 0 . 809间，表现为一般剪切作用类型，其中早期为以简单剪切组份为主、晚期为以纯剪组份为主的一般剪切作用类型。
Therefore unifies the data mining technology and the application , at the same time maintains the system to be extensional and the flexible , constructing data mining system that suits the enterprise user has become one of questions which is most urgent needs to be solved at present 因此如何将数据挖掘技术与应用相结合,同时又保持系统的可扩展性和灵活性,构建适合企业用户的数据挖掘商业应用系统已经成为目前最迫切需要解决的问题之一。
The results indicate : ( 1 ) the distribution of magmatic rocks shows the feature that in the middle and western part of the study area basic igneous rocks dominate , and in the middle - eastern part intermediate rocks are predominant , while in the southeastern part acid ones are developed . ( 2 ) in the area west to the shiwandashan basin , intermediate magmatites were controlled by deep ne - striking and nw - striking faults , especially at the conjunction site of these two group faults , magmatic activity was strong ; and its tectonic background can be attributed to extensional continental rift 其中，在十万大山盆地以西地区的偏基性岩浆活动受北东和北西向深断裂控制明显，尤其以此两组断裂交汇处的岩浆活动强烈，盆地构造背景属大陆伸展裂谷环境；在十万大山盆地以东地区为偏酸性岩浆活动，主要受东吴运动形成的钦防造山带的控制，属大陆边缘造山带或岛弧造山带环境。
Yinggete - bagemaode metamorphic core complex belt with three - layer construction is put forward , which evolved from late jurassic to cretaceous . the extensional simple shear model of the chagan fault depression is established . the tectonic evolution and the dynamics character of chagan fault depression and its adjacent mesozoic - cenozoic basins are discussed : at the end of triassic continental orogeny increased crust thickness crust uplift and denudation were happened ; jurassic was a period of local partly extensional collapse of erogenic belt and cretaceous was a period of widely extensional collapse of postorogenic erogenic belt ; cenozoic was a period of the development of stable intracontinental depression with the character of long distant collision response and weaked compression flexure 讨论了查干凹陷及邻区中-新生代盆地构造演化及其地球动力学特征，三叠纪(印支期)为陆内造山作用与地壳增厚、隆升剥蚀阶段；侏罗纪(燕山早期)为造山后造山带的局部伸展垮塌阶段；白垩纪(燕山晚期)为造山期后大规模伸展垮塌作用与伸展盆地的发育阶段；新生代(喜山期)为远距离碰撞效应与弱挤压挠曲性质的稳定大陆内坳陷的发育阶段。
Viewing from the global tectonics , the authors dynamically described the dialectical relationships between extensions and compressions in time special 4 - d , and pointed out the different tectonic deformation systems corresponding to different tectonic dynamical environments . considering the geological evolution of sichuan basin , from nine aspects , the authors proved that the tectonic dynamical environments of sichuan basin , after its formation , has experienced the early extension , middle transition and late compression environments . correspondingly , as the paper suggests , a considerable attention need to be paid to the comprehensive studies of the early extensional structures , middle inversion structures and the late compression structures of sichuan basin when analyzing its tectonics 从全球构造着眼，动态地从时间-空间四维阐述了拉张-挤压构造动力学环境的辩证关系，指出了不同构造动力学环境对应于不同的构造变形系统。结合四川盆地地质演化历程，从9个方面论证了四川盆地自其形成以来，构造动力学环境曾经历了早期拉张中期过渡晚期挤压的过程，相应地在对四川盆地进行构造分析时，要注意早期伸展构造中期反转构造晚期挤压构造的识别和综合研究。
Recently , two important things need to be further addressed : ( 1 ) the time of the transition from compressional to extensional setting , and the geodynamics processes in se china ; ( 2 ) the relationship between polymetallic mineralization and lithospheric thinning and crustal extension 近年来随着研究的深入，逐渐凸显出两个重要的地质问题需要解决： ( 1 )中国东南部晚中生代构造属性的转变时间及地球动力学演化过程； ( 2 )多金属成矿作用与岩石圈伸展减薄及地壳拉张的关系。
In order to formulate the reasonable rejection standard of automobile and the synthetic evaluation of performance , based on synthetic analysis of the performance indexes of various systems part , this paper has established the extensional matter - element evaluation model , and brings forward the extension evaluation method with relative functions 为了制定合理的汽车报废标准及综合性能评价，本文在综合分析汽车各系统部件性能指标的基础上，建立了汽车完损度可拓物元评价模型，并给出了基于关联函数的可拓评价方法。
