查询词典 plane graph

In this paper,we study the problem finding basic circle in plane graph,in which the number and coordinate of nodes and the node number of two ends of the side is given,we create a method,which is enlightened by the"proble of find way in labyrinth",to find way in branch point and then to find basic circle.

论文讨论了平面图形中存在着节点和边，在已知节点的坐标、标号以及边的标号和边两端的节点标号情况下，对其中存在的一阶环进行计算机搜索问题，提出了受"走迷宫"问题启发的一种在分叉点沿一定的方向进行搜索的方法。

In Chapter 4, we calculate the equitable total chromatic number of some specific graphs. For some plane graph, we also calculate the vertex-edge-face equitable total chromatic number.

在第四章中主要计算了一些特殊图的均匀全色数，对于一些平面图计算出了它的均匀全色数。

A configuration is reducible if no minimal 5 chromatic plane graph can contain it.

如果没有极小5色平面图能包含某个构形，就说此构形是可约的。

The method defines two types of oriented 4-valent plane graph: G_e and G_o, whose vertices are covered by E-tangles and O-tangles, respectively.

这一方法定义了两种有向4-度平面图：G_e和G_o分别用E-tangles和O-tangles覆盖两种有向4-度平面图的顶点。

It is well known that every triangle-free plane graph is 3-colorable.

我们知道一个著名的定理：不含3-圈的平面图是3-可着色的。

A configuration is a connected cluster of vertices of a plane graph together with the degrees of the vertices.

一个构形是面图的一连串连通的顶点与这些顶点的度。

In this article, we give a new form of Steinbergs conjecture by showing that every plane graph without i(4≤i≤6) faces in which any two triangles have distance at least 3 is 3-colorable.

在本文中，首先给出了Steinberg猜想的一个新形式，证明了没有4到6面的平面图中如果任意两个3圈的距离至少为3，那么这个图就是可以3色的。

Thus, the conjecture holds if G is a plane graph with triangle-free.

结合结果，给出猜想的一个正面的肯定。

We also get another expression of Steinbergs conjecture about plane graphs, that is, every plane graph without i(4≤i≤5) faces in which any two triangles have distance at least 3 and no 3-face is adjacent to any 6-faces is 3-colorable.

我们还得到平面图的一个类似结论：没有4、5面的平面图中如果任意两个3圈的距离至少为3，而且没有3面和6面相邻，那么这个图也是可以3色的。

This invention relates to three-dimensional seismic data processing quality monitoring technology. Selecting time-window and analysis frequency for FFT to obtain frequency-domain conversion result for every channel; taking mean-filter to obtain the statistic excited energy or noise disturbance; plotting all results on plane graph to monitor the 3D excited energy or noise disturbance; taking normalization and autocorrelation to all earthquake channel; summating all autocorrelation statistic result to obtain opposite statistic autocorrelation result; finding out and plotting the zero-crossing of autocorrelation on plane position for monitoring excited wavelet.

本发明涉及一种三维地震资料处理质量监控技术，步骤是：选定时窗和分析频率；对某炮各地震道在时窗内做快速富立叶变换，得到道数据在频率域变换结果；对同炮的所有地震道做频率域中值滤波，得到该炮的统计激发能量或噪声干扰量结果；将所有炮的计算结果绘到各炮点平面图上，监控三维激发能量或噪声干扰；对地震数据某炮的各地震道做归一化自相关；对同炮的所有地震道的自相关统计求和，得到该炮的统计自相关结果；寻找该炮统计自相关的零交叉时，将所有炮的零交叉时绘到各炮点平面位置上，完成激发子波监控。
