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

现在，跟成熟一起，代数软件是简单的学习和代数变得容易。

So we come out of public school knowing how we should feel socially, but unable to do simple algebra.

因此从公立学校出来我们知道感受社会，但我们不能做简单的代数。

Long lists of references, simple bits of algebra, or other documentation are good candidates for footnotes.

一个长序列的参考文献、简单的代数、或其他的文献证据，可以用作脚注。

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。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
