Moreover, two classes CBIR system were discussed. Especially, the emphasis was put on the GIS supported CBIR and a set of such querying algebra operators was presented. The system frame and the general schema of CBIR based on image feature index were discussed as well.

并以GIS要素与遥感图像的空间关系为基础，着重分析了GIS支持的遥感图像基于内容查询系统的主要算子，对基于图像特征索引的内容查询，也作了一般形式化的讨论并给出了应用的系统框架。

Its theoretic foundation is integration geometry, random theory of set, topology, modern probability, algebra, theory of set, graph theory, and so on.

其最基本的数学理论基础是积分几何和随机集论，同时还涉及到拓扑学、现代概率论、近代代数、集合论、图论等一系列数学分支。

Can't. As long as focusing on algebra means you get a C in psychology, or as long asyou get lectured for falling asleep in history on mornings after late gymnastics meets,you are being pushed away from excellence toward anxious shoddiness.

你专心学习代数，心理学就得不到好成绩；如果你因为前晚参加体操训练，第二天早上的历史课打瞌睡而被罚；只要这种情况不改变，就有压力迫使你放弃卓越，追求焦虑的平庸。

In chapter 1, similarity and perturbations of nest subalgebras of factor von Neumann algebras are studied. A similarity theorem is given (see Theorem 1. 2. 3), and it is shown that similar nests in a factor von Neumann algebra are close.

第一章研究因子von Neumann代数中套的相似性和套子代数的摄动，获到一个相似定理（定理1.2.3），其几何意义是：因子von Neumann代数中相似的套聚拢在一起并可向外扩展。

This dissertation studies some topics in soliton and integrable system,which mainly include as follows:exact solutions especially travelling wave solu-tions and solitary wave solutions,Painlevēproperty,transformation,similarity reduction,symmetries and their Lie algebra structure,generation ofsoliton hierarchy and their zero curvature representation,Hamiltonian struc-ture,Lax or Liouville integrability,nonlinearization of Lax pairs,applications ofWu's method and symbolic computation.

本文研究内容涉及到孤立子和可积系统的多个方面：精确解特别是行波解和孤波解，Painlevē性质、变换、相似约化、对称及其Lie代数结构、孤子族的生成及其零曲率表示，Hamilton结构，Lax和Liouville可积性、Lax组的非线性化以及吴方法和符号计算在上述研究中的应用。

Now, with maturity, the AlgebraRules are simple to learn and Algebra becomes easy

When I grow up, learning from simple to more difficult algebra calculus, from basic science to chemical and biological, and I used to use the know-how has been watered down.

当我长大后，学习内容也从简单的代数转到更难的微积分，从基础科学转到化学和生物，而我以前的诀窍使用起来也大不如前。

Diabetes is a social disease that affects several million people worldwide.

糖尿病是一个社会性疾病，全世界有数百万人罹患此病。
