查询词典 representation

Assume a Lie algebra g has a form B which has all the useful properties of Killingform:bilinearity nondegeneracy,symmetry and invariance.Note that for such a Liealgebra the adjoint representation is equivalent to the coadjoint representation.We callit a symmetric self-dual Lie algebra and the form B an invariant scalar product.

在第一部分的最后一节，我们引进了拟Heisenberg代数的概念，证明了这些李代数均为具有非极大秩的CN李代数，进一步我们还证明了这些CN李代数构成的集合与极大秩幂零李代数构成的集合之间存在着1-1对应关系。

By analysis of frequency spectrum based on MATLAB platform, wavelet method in the application of cutting out a section of inputting earthquake wave was presented. In the process of pseudo dynamic test results, the method of non-dimensional representation and analytic representation of hysteretic curve was provided. The above two methods will help to compare dissipation energy capacity of this structure at the different acceleration peak value stage of pseudo dynamic test more precisely and comparably.

通过基于MATLAB的地震波频谱分析，说明了小波分析方法在拟动力试验中地震波截取方面的应用：在拟动力分段试验数据的处理方面，本文将试验结果的无纲量表示方法以及曲线的多项式拟合法引入滞回曲线的数据处理，这将有助于拟动力试验不同加速度峰值条件下，各阶段结构耗能能力的客观比较。

On the basis of Earth surface space using reference ellipsoid as height basis, map space using Gauss-Kruger projection plane as height basis, a viewpoint is proposed that map projection actually establishes corresponding relationship between the height bases of two different spaces above. From the viewpoint of projection and visible representation, the relationships among earth surface space, RS imagery space and map space are analyzed; the differences among different representations of earth surface space are identified theoretically; virtual reality is applied to the representation of land surface space, and a prototype of real 3D virtual reality system based on spatial information is developed. By means of digital simulation, virtual reality representation of land surface space in visual image space is realized.

在以参考椭球面为高程基准面表征地表空间、以高斯-克吕格地图平面为高程基准面表征地图空间的思想基础上，提出了地图投影实质上是建立两个空间的高程基准面之间关系的观点；从投影和可视表达的角度，分析了地表空间、遥感图像空间、地图空间之间的关系，从理论上区分了对地表空间的不同表达方式之间存在的差别；将虚拟现实技术应用于地表空间的表达，研制了空间信息三维虚拟现实系统原型，利用数字模拟技术在视像空间实现了对地表空间的真三维虚拟现实表达。

In this paper, we proposed a novel text representation model named Graph Space Model and introduced a novel way to measure the representation ability of a text representation model.

According to the characteristics of soybean cultivation areas, the knowledge data representation, combining with the pattern representation and the knowledge unit representation, is used in the system. Under a cross-platform system compeleted by using the module technology and the distribution network technology, this method is helpful to the inference machine's design and implementation.

根据大豆栽培领域问题的特点，本研究选用模式表示与知识单元表示相结合的知识表达方式，在利用组件技术与分布式网络技术实现的跨平台系统下，该方法有助于推理机的设计与实现。

The original contributions of this dissertation: Considering context as a holistic unit of representation, using context representation as a technological approach to the design for the experiential learning, proposing an EL model, creating a conceptual framework of context representation.

论文的创新性贡献体现在：将情境作为整体表征的基本单位；探讨了从情境表征的角度设计体验学习的新路径；提出了体验学习过程模型；构建了情境表征的概念框架。

The paper commences with the analysis of personal identification of the autobiographers, points out that they mostly put emphasis on reflection and discovery of self-value, which are abundant in pursuit of value and show the birth of modern personality witha modern connotation consciousness and the spirit of science.Chapter III, how to write about I, analyzes two representative aspectsselected from many characteristics shown in artistic expression of the autobiographies, one of which is that its method of representation is not limited the single way of classic Chinese autobiographies, i.e, the mixture of representation and argumentation , and thus gives birth to psychologized representation; the second of which is that its surrounding description shows great mobility, which is different from stiffness and other literary forms.

本文首先从现代作家自传表现出的传主们各异的身份自认的分析中，指出他们的自传大多侧重于对自我存在价值的反思与发现，并且在他们的诸种反思中不仅蕴涵着丰富厚重的价值追求，而且也昭示了现代人格的诞生，其人格的现代性内涵主要包括叛逆精神、忏悔意识和科学精神。

Halliday ( 2000: 441/516 ) defines "projection" as "the logical-semantic relationship whereby a clause comes to function not as a direct representation of (non-linguistic) experience but as a representation of a representation", and this relationship "is always, in fact, a relationship between processes—between a mental or verbal process on the one hand, and another process of that is mentalized or verbalized by it."

Halliday(2000：441／516)将投射定义为小句复合体中两个小句之间的这样一种逻辑语义关系，其中&一个小句的功能不是对经验的直接表述，而是对表述的表述&，这种关系&总是存在于过程之间——其中一个为思维或言语过程，而另一个过程则被它思维化或言语化了。&

This representation method not only wides SRC Ontology's 8 topological relation representation method, and provides more explicit formalization representation for spatial relation ontology modeling, but also make the practical application possible.
