查询词典 null algebra

Vector spaces are a central theme in modern mathematics ; thus, linear algebra is widely used in both abstract algebra and functional analysis .

向量空间的一个中心主题在现代数学，因此，线性代数被广泛使用在抽象代数和功能分析。

In addition to calculus with linear algebra, I had two semesters of mathematical analysis, partial differential equations, abstract algebra was also a senior this semester in the measurement theory.

除了微积分跟线性代数，我还上了两个学期的数学分析，偏微分方程，抽象代数还有在大四这个学期上的测量理论。

Mode of exquisite visual is a visual image thinking in comparison to understand some of the more abstract algebra problem for preliminary exploration mode, the purpose is to make the direct-viewing can better applied to high school algebra teaching

模式直观讲究的则是一种以比较直观形象的思维来理解一些较为抽象的代数问题，为此初步探索模式直观的目的在于使之能够更好地应用到中学代数教学之中。

I am a professor of the Department of Applied Mathematics at Xiamen University, a doctoral supervisor, and also the mentor of Mr. Ben Niu in the course Linear Algebra and the course Abstract Algebra. Therefore I have good knowledge of his academic capabilities and potential, so to speak...

我是厦门大学数学系教授、博士生导师，也是牛犇线性代数和抽象代数的授课老师，可以说我对他的学习能力和发展潜力是比较了解的，听说他正申请攻读贵校的硕士研究生课程，我当然全力支持。。。

This dissertation is changed into two parts. The first part, the theory and application about Wu-Ritt differential characteristic sequence method are discussed, which involves the theories of differential equations, abstract algebra and computer algebra etc.

本文共分两部分，第一部分讨论微分特征列法的理论和应用问题，涉及到微分方程，抽象代数，计算机代数等重要学科。

Higher algebra is an abstract and theoretical subject.In the teaching,it is hard to join the examples with the real life.This gives people the impression that learning algebra is not useful.

高等代数是一门抽象性和理论性较强的学科，在教学中所涉及的例子较少能与实际生活密切相连，让人感觉到学习的内容与生产实践脱节，体现不了数学的应用价值。

We explain the basic conception of the Lie group, Lie algebra and Riemannian manifolds in detail, deeply analyze and research the Special Euclidean Group SE(3) and se(3) in the Lie group, Lie algebra. Establish the relation between the adjoint transformation Adg and the operatorφ(k + 1,k) under a particular condition , substitute the operatorφ(k + 1,k)with spatial adjoint operator Ad kk ?

在多体系统动力学理论体系中，详细阐述了Lie群、Lie代数和Riemannian几何的基本概念，对Lie群、Lie代数中的特殊Euclidean群SE(3)和se(3)作深入分析与研究，建立Lie括号下的伴随变换Adg在特定条件下与空间算子代数理论中的空间变换算子φ(k + 1，k)之间的相互关系，并将空间伴随算子Ad kk ？

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。

Based on White event algebra, the formal framework is extended for event algebra, considering semantic definition of events in more concise temporal relationships of events to enhance the expressiveness of event query language while taking into consideration event selection and consumption policy-the context consumption policy to improve the performance of event detection.

基于White事件代数，扩展了事件代数的形式化框架，在形式化框架中考虑复合事件在更精细的时间关系下的语义定义，以增强事件代数的表达能力，同时考虑与应用相关的事件选择和消费策略-上下文策略，以提高事件检测的性能。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
