More precisely,we shall say that two graphs are isomorphic if there is a one-one correspondence between their vertices which has the property that two vertices are joined by an edge in one graph if and only if the corresponding vertices are joined by an edge in the other [3],Another graph isomorphic to the graphs in Figs.

更准确地说，如果两个图的顶点间存在一一对应，使得在一个图中有一条边连接两个顶点在另一个图中相应也有且仅有两个对应顶点由一条边相连，则说这两个图是同构的。

Then, by taking the local features provided by users as portions of the AAG, and the whole CAD model as the whole AAG, the problem of local feature matching is transformed into that of subgraph isomorphism. Subgraph isomorphism is a NP-complete problem.

在局部匹配过程中，用户输入的局部结构被表示成"子图"，待匹配的整体CAD模型被表示成"大图"；则在整体CAD模型中，检索局部结构的问题就被转换成在"大图"中寻找同构"子图"的问题。

在焊缝图象系统的研制中，基于结构光空间付氏变换的光纹图象数学模型，建立了焊缝图象处理算法，并基于焊缝三维空间特征的规则模型，建立了焊缝图象分析系统，使焊缝检测与分析的精度和可靠性达到了弧焊机器人焊接参数自动规划及焊接路径自动规划的精度要求。

The model applies use-case view (use-case diagram, sequence diagram, collaboration diagram and activity diagram), logical view (class diagram, object diagram and state graph), component view and deployment view to carry on a detailed description respectively, presenting a stock information system model from each one possibly.

该模型通过用例视图（用例图、时序图、协作图和活动图）、逻辑视图、组件视图和部署视图分别进行详细的描述，尽可能地从各个方面呈现出股票信息系统模型。使用C#和。NET对股票信息系统进行编程，实现了有效股票基本信息的提取、组织和呈现。

In order to correct these geometric distortions on satellite SAR image, and cooperate this information on SAR image with the information from other sensors, it is necessary to geocode original SAR image, and obtain correct standard geocoded image in the defined map projection.

为了校正星载SAR图象的几何畸变，使SAR图象上的数据信息和其它传感器上得到的信息进行融合，必须对星载SAR原始图象进行地理编码，得到校正后的统一的地图坐标系上的标准地理编码图象。
