最后，我们利用辛空间中的所有一维向量子空间及极大全迷向子空间构作了一类二部图，证明了此图是一个距离半正则图，其二部半图是辛图的补图。

Phase correlation and then reaches image mosaic by graph cut and poisson image fusion.graph cut is used to find a globally optimized seam-line for deghosting while poisson image fusion is used to realize smooth mosaic without exposure difference.a new weight calculation method based on the statistics of guadient direction histogram is presented here in order to robustly realize graph cut.an edge transition poisson image fusion method is also proposed to reach exposure difference removal

该方法在相位校正的基础上将图切割和泊松融合相结合实现拼接，图切割用于搜索全局最优的缝合线以去除鬼影，泊松融合用于曝光差异的处理。本文给出新的基于梯度方向直方图统计的权值计算方法，实现稳定的图切割。另外，本文还设计出重叠过渡的泊松融合方法，较好地完成图像合成。

Finally this paper consideres an applicable case-the symbolic transition graph,then the generalized symbolic observation graph SOG and symbolic congruence graph SCG can be finite,so authors' algorithm is feasible for weak bisimulation and observation congruence.

此时由符号双迁移关系生成的符号观察图和迟符号同余图必为有穷图，因而我们的弱互模拟等价算法是可行的。

it was a routine way for graph- drawing based on coordinate data in application software to program and graph processing,because from coordinate data to graph it is uniqueness.in hydrologic analysis,we calculated related data according to figure parameters,as using rainstorm isoline to reckon average rainfall in the river basin.through examples and analysis,the paper proposed methods for curve numerical translation and area calculation by vb.

在应用程序编制和图形处理的软件系统中由坐标数据可以绘出图形是常规的途径，但有曲线图形，要生成坐标数据，至今还没有通用的方法，因为由坐标生成图形是唯一的，而反过来由图形转换为数据是非唯一的。在水文分析计算时，有时需要根据图形参数进行有关数据的计算，如用暴雨等值线图计算流域平均雨给出量的时候。通过分析和计算实例提出了利用vb实现可满足使用要求的曲线数值转换和封闭图形的面积计算方法。

According to the three-dimensional finite element analysis, the graph of axis force on steel, the graph of Z displacement on steel and the graph of whole transmogrification on girder are drawn.

通过模型分析计算得出的结果，得到钢筋轴力的分布图，相应的钢筋Z向位移曲线和梁的整体变形图，钢筋应力及混凝土平均应力曲线图，最后根据分析结果推导出钢筋应力与荷载的关系公式。

The minimum number of verticesof G whose removal from G results either in a graph that is no longer connected or in a trivial graph with a single vertex: at least K vertices must be removed from a graph with K-connectivity.

从图g中移去顶点使图成为一个非连通图或是单个顶点的"平凡图"的最少顶点数称为连通度。一个k连通度的图至少必须从图g中移去k个顶点才能成为非连通图。

We apply the results in Chapter 2 to the equitable list coloring of graphs and prove that a graph G is equitably △-choosable if G is a plane graph without i-cycles, 3 ≤ i ≤ 5, or a plane graph without 4-cycles(or 5-cycles) and 6-cycles.

从而得出不含3-圈，4-圈和5-圈的平面图和不含4-圈(或5-圈)和6-圈的平面图GΔ(G≥6均有一个Δ-均匀列表染色。

In a graph-theoretic version for a graph G,it is to find a set F of added edges such that the graph G+F is chordal and |F| is minimized.Here the minimum value |F| is called the finll-in number of G,denoted as f.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
