In this paper, firstly, the embeddability of near-triangular graphs on the orientable surface is studied. By using Petersen's Theorem about 1-factor, we first prove that for a near-triangulation on the orientable surface, its geometry dual graph has a 1-factor; then after a procedure of operation leaded by the 1-factor, we show that if a graph G triangulates some orientable surface S_g, then G has a near-triangular embedding in S_h for h = g,g + 1,...,β(G/2」, where β is the Betti number of G. Hence we obtain a conclusion: A near-triangulation of the orientable surface is upper-embeddable. As a generalization, a class of near-quadrangulation is studied, and similar results are obtained.

本文首先研究了近三角剖分的可定向曲面嵌入性质,通过运用Petersen关于1-因子的定理,首先证明了对于可定向曲面上的三角剖分,其几何对偶具有1-因子;然后在1-因子的导向下,通过做一系列增加亏格的手术,证明了如果一个G三角剖分可定向曲面S_g,那么G可以近三角剖分可定向曲面S_h,这里h=g,g+1,…,「β(G/2」,β是指G的Betti数,从而得出推论:可定向曲面上的三角剖分是上可嵌入的,作为推广,又研究了一类近四角剖分的可定向曲面嵌入性质,并得到类似的结论。

The main work of this paper is that we have given the edge game chromatic number of cycle likes, fan graphs, flowers, Halin graphs, and the upbound is sharp for cycle likes and Halin graphs, it is also a good example for the study of planar and outerplanar graphs.

Firstly, we give out the definitions of L-graph and partial L-subgraph, and we ob-tain some properties of partial L-subgraphs. Secondly, continuous mapping is intro-duced respectively between L-graphs and between L-cotowers, and the relationshipbetween the category L-FG of L-graphs and the category FG_L~C of L-cotowers isstudied. At last, we study the finite topological property of the category L-FG, andgive out the concrete constructions of finite product and finite coproduct.

Aiming at the multiple loop structures in quality management process network, an improved graph pattern mining approach based on Apriori algorithm is put forward, where a frequent pattern of size k, denoted as G, is joined with another frequent pattern of size k, denoted as G, to form a candidate frequent pattern of size (k+1), if there exists a source vertex s in G and a sink vertex e in G such that the graph derived from G by subtracting node s equals with the graph derived from G G by subtracting node e.

采用基于APriori方法的频繁活动序列挖掘算法,认为k-频繁集中,当一个减去其中的一个源顶点后,如果所得到的与另一个减去其中的一个沉顶点后的相同时,可以连接生成一个(k+1)-候选频繁,从而减少了传统Apriori算法迭代过程中生成的冗余候选频繁的数目。

The math models of the tree structure chart and the net structure chart are formed by describing the different road state abstractly.The tree structure chart model is presented without consideration of U structure and ring structure. This kind of model has a notable feature: there is a line only between the two dot in the chart, which means that there is only one road from one point to another point in expressway ,so the tree structure chart is called "single roads chart".

在不考虑U型路段和环路的情况下,提出了高速公路的树状结构模型,该模型具有一个显著的特点:中两点之间有且仅有一条连线,这意味着由高速公路上的一个地点到达另一个地点仅有一条通路,也称这种高速公路树状结构为"单路径";考虑到包含U型路段和环路的高速公路路况,提出了高速公路的网状结构模型,这种模型可抽象成一个连通,即中任意两点之间至少有一条直线相连,这意味着由高速公路上的一个地点到达另一个地点有多条通路,也称这种高速公路网状结构为"多路径"。

Vectorgraph can be converted to a bitmap, but in turn bitmap converted to vectorgraph technical comparison difficult to achieve, a lot of graphic design software that support the use of pixel figure converted to vectorgraph, a general description of the software for free vector function realization, so that we can on the basis of vectorgraph to do the editing, but this kind of conversion sometimes is time-consuming, and sometimes does not achieve the expected results, it is generally used for relatively simple bitmap, or you would like some special effects.

矢量可以转换成位,不过反过来把位转换为矢量技术上比较难实现,很多形设计软件都支持将像素转换成矢量性,一般可用矢量软件的描摹功能实现,这样我们就可以在矢量形的基础上再做编辑,但这样的转换有时候会很耗时,有时候并不能达到预想的效果,一般用于比较简单的位,或者想要表现一些特殊的效果。

Isogram addition with line, histogram, and Lorenz plot is latterly realized in HBACIS so that the results of the inquiring, calculating and analyzing of the climate information can be visually displayed. The successful exploitation of HBACIS shows that the B/S system adopted JSP can totally satisfy the requirement of the agricultural climate information system. For one thing, JSP with the characteristics of high efficiency and security, multiplatform and expansibility, basing on the object oriented language-JAVA, can be sustained widely, and is easy to exploit and maintain. The JSP tags can be extended and the components are reused. For another, the client side of the B/S system is all applied with the browser as the interface, which is very simple and wieldy.
