The relational database is used to organize data. The pre-processing with graphical human-computer interaction and 3D visual output is applied as a dramatic analysis method for engineer including data form, sample contour, isobar graph, vector graph, histogram and so on.

该系统以关系型数据库组织各种数据，完全实现了人机图形交互式前处理及三维可视化输出，为工程人员提供了包括数据表格、取样曲线、等位线、等位面图、向量图及二元函数图等一系列生动形象的数据分析手段。

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。

The recognition method of circuit drawing plotted by AutoCAD is proposed It uses the topological graph to describe the electrical symbol s drawing and adopts the isomorphic graph algorithm to recognize the electrical symbols, meanwhile,the circuit wires are also recognized It can recognize the circuit drawing automatically with high accurac

提出自动识别使用AutoCAD绘制电气原理图的方法该方法利用拓扑图表示电气符号，采用图的同构算法识别电气符号，并在识别出电气符号的基础上识别电路线该方法能够以较高的准确率自动识别电气原理

Since the graph isomorphism problem is neither known to be NP-complete nor to be tractable, researchers have sought to gain insight into the problem by defining a new class GI, the set of problems with a polynomial-time Turing reduction to the graph isomorphism problem.

由于图同构的问题既不是已知的NP完全问题，也不是听话的，研究人员设法深入了解这个问题，确定了一类新基的一系列问题，多项式时间图灵减少的图同构问题。

Graph's isomorphism is one of the basic problems and NP problems in graph theory.

图的同构是图论学科中的基本问题之1，属于图论中多个NP—完全问题之1。

A new method for understanding the construction of dual links has been developed on the basis of medial graph in graph theory and tangle in knot theory.

基于图论中反转中间图的方法和纽结理论中的缠绕理论，我们提出了构建对偶链环的新方法。

It just makes it that much easier for your audience to read and understand points on a graph if they're labeled within the graph and not to the side, like it generally is.

对你的听众而言，如果你能够将在图表中标出某一点资料的标签放在表内，而不是平时常用的在表格旁边列出，那么可以更便于他们阅览。

Figure 1 is a composite graph that illustrates the "mound" of conditioner on the lane going from channel to channel. As you can see, this graph does not show a wall. The heavy application of "oil" in the middle of the lane can make a bowling ball "bounce" as though it has hit a wall when delivered from the middle of the lane toward a part of the lane outside the 10 board.

图一是球道上每块板所上的油量厚度总合，图上看不出上头有道墙，中间部份的厚重油量会使球从中央往外侧的10块板处送去时，在球沟附近会好像有一道墙把球围起来，使它不会落入球沟里。

Let G be a simple graph. A line of graph G is allowed if it lies in some perfect matching of G.

设G为一个简单图。G的一条边为容许边，如果它属于G的某个完善匹配。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
