In order to improve the expression capability and the performance ofthe graph transformation in applying to software evolution, a softwareevolution operation description language SEOL (Software EvolutionOperation Language) is proposed, and the structured operational semantics on SEOL is studied, and then the semantic equivalence analysismethod about software evolution operation is described. To the SEOLexpression, the dissertation builds the corresponding processingmechanisms, which include the basic principles and the processing flow,and discusses the graph transformation description in SEOL.

为提高图变换在软件演化应用中的表达能力和处理性能，结合谓词逻辑，论文提出了软件演化操作描述语言SEOL(SoftwareEvolution Operation Language)，研究了SEOL语言的结构化操作语义，指出了软件演化操作语义等价的分析方法，针对SEOL语言表达式，构建了相应的处理机制，包括处理的基本原理和处理流程，讨论了图变换操作的SEOL描述。

After introducing the AOP, there are components, system connectors, aspect connectors and constraints in architecture. The UML and ADL description of each model are given, and achieves the transform from semi-formal to formal model, and the model's refinement and verification, which provides a good foundation for the development of tools.

引入方面的软件体系结构是由构件、系统连接件、方面连接件以及约束构成的配置格局，不仅给出了体系结构中各元素的统一建模语言和体系结构描述语言的描述，实现体系结构模型从半形式化到形式化的转化，而且实现了模型的求精和验证，为各种工具的开发提供了一个良好的基础。

Firstly, the definition of cooperative transactions is given and the states of them are specified. Secondly, the dependencies among cooperative transactions and those between cooperative transactions and outside environments are specified in terms of states of cooperative transactions. Finally, the serializability correctness criterion for the presented model is specified by state dependencies of cooperative transactions.

首先给出了协同事务的定义，并描述了协同事务的状态，然后从协同事务的状态角度刻画协同事务之间、协同事务与外部环境之间的复杂依赖关系，最后用协同事务的状态依赖描述了可串行化正确性准则。

In the past,description on topological spatial relationship of GIS was based on basic theory of point set topology.

过去对GIS拓扑空间关系的描述均是基于点集拓扑学的基本理论，描述点、线、面、体间的覆盖、相邻、相交和相离等关系。

Meanwhile, the shopworn epithet "beautiful", which we can safely identify as a European concept, describing certain qualities in Western art, may yet be applied informally, and objectively, to characterise a piece of Buddhist sculpture, for example, which exhibits the same or similar qualities; but it should be acknowledged that in using it we may be extending the meaning of the concept, and possibly creating further confusion about it.

而同时，如果我们用老掉牙的"美"，这个我们可以安全地甄别为欧洲概念，用来描述西方艺术的某些特点的概念，来描述似乎显示了相似的特点的菩萨雕塑，我们不得不承认，我们可能会制造混乱，延伸了这个概念的外延（对比前面我们关于种族的讨论）。

So,the massive data acquired in the period from January to December in 2006 and authorized by CAIDA Skitter project were used to analyze the searched topological data at CAIDA(cooperative association for Internet data analysis) router level,thus describing the characteristics of the distribution of the degree s of nodes at router level.

针对目前对路由层面的Internet拓扑研究较少的问题，基于2006年1月至2006年12月采集的CAIDA Skitter项目授权的海量数据，对CAIDA路由层面拓扑探测数据进行了分析，描述了路由级节点度分布的幂率性。在此基础上计算出了更能体现网络拓扑层次性的各节点的核数，描述了节点核的幂率分布性质，进一步分析了节点核数与度之间的关系。研究表明，对低核节点，其度分布存在着幂率性质

The polarizations of the strings also change with the soft pedal because the third string will be polarized more horizontally, which contributes to the gentler sound.

上述的讨论，对于钢琴真正音响的成因，只有一些特性的描述，并没有量化的讨论及精确的机制描述。

Possibly the use of a triangular mesh would have made the description simpler: that is to say, it might be that we could describe the surface more accurately with a coarse triangular mesh than with a fine square mesh, and so on.

也许用三角形格子的网会使描述更为简单：也就是说，用较稀的三角形网格也许比用较密的四方形网格能够更精确地描述这个表面，如此等等。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
