In chapter 2, a relationship between three types of oriented triple systems mts, dts, hts is discussed, i. e., if the block incidence graph of an mts ( v, a ) is 3 edge - colorable, then we can get three disjoint dts ( v, ) s and four disjoint hts ( v, ) s
第二章討論三類有向三元系mts ， dts ， hts之間的一種關聯關系：如果一個mts （ v ， ）的區組關聯圖是3 -邊可染色的，則可得到三個不相交的dts （ v ， ）及四個不相交的hts （ v ， ） ，且對應區組的基礎集均一致。 -
Firstly, the connected end sets of the relay lines are got using the breadth first search algorithm and the connected relationship of wiring terms is got in the electrical circuit diagram according to different cad block structure of different element type. secondly, the appropriate specification of the relay element is chosen by using the equinoctial graph algorithm, and the panel layout diagram is generated automatically by the combining automatic layout and manual intervention. finally, the optimized path algorithm which passes each vertex in the completed non - directional graph once and only once is put forward, this algorithm and the prim minimum spanning tree algrotithm can generate the inner panel wiring diagram and terminal wiring diagram automatically
首先，採用廣度優先搜索演算法查找電氣原理圖中的連通導線端點集，並根據不同類型的繼電元件對應的cad圖塊結構的不同，得到電氣原理圖中元件接線端子之間的連接關系;其次，根據二分圖匹配演算法為電氣原理圖中繼電元件選擇合適的型號和規格，並採用人工干預和自動布置相結合的方法完成屏面布置圖的自動生成;最後，提出了完全無向圖中經過每個頂點一次且僅一次的優化路徑演算法，利用該演算法和經過預處理的prim最小生成樹演算法自動生成屏內安裝接線圖和端子接線圖。 -
In this graph, the galactic plane is horizontal and we ignore the distances. note that the gas and dust in our galaxy not only block the stars in our galaxy, but also the galaxies far away. taking this into consideration, the distribution of the galaxies is fairly uniform
圖中中間的水平線標示出銀河系平面，銀河系的氣體塵埃除了掩蓋了背景星光，亦同時遮蔽了遙遠的星系，撇除了這個因素，我們會發覺星系在天空的分佈是頗為平均的。 -
Ldpc ( low density parity check ) code is a kind of linear block code that defined by very sparse parity matrix or tanner graph, and it is also called gallager code since gallager initially presented it
Ldpc （ lowdensityparitycheck ）碼是一類用非常稀疏的校驗矩陣或二分圖定義的線性分組糾錯碼，最初由gallager發現，故亦稱gallager碼。 -
With the help of metis, which is a software package in static graph partitioning, we construct a type of block jacobi preconditioner
J時十u個1任用問題，分別用該分解作近似川j i 』 d寸十八』 。 -
Since the crossing numbers of graph equal the sum of the crossing numbers of all its 2 - connected blocks, we work on the crossing numbers of graphs for n < 9 with unique 2 - connected block.
由於圖的交叉數等於其所有二連通分支的交叉數的和，本文計算了n 9的所有單二連通分支圖的交叉數。 -
In chapter 4, fault isolation based on statistical methods is discussed. firstly, the fault isolation ability of multi - block principal component analysis is tested on the tennessee eastman process. then principal component analysis and signed directed graph are combined, and the method is applied to a continuous stirred tank reactor
第四章探討了多元統計法在故障分離中的應用：首先以田納西過程為實例檢驗分塊主元法的故障分離能力，然後把統計法故障診斷與符號有向圖法結合，並把這一方法應用到一個連續攪拌的化學反應釜中。 -
Then, with this property and the concept of block graph, we obtain four properties of shortest 2 - connected steiner networks. in chapter 3, we are mainly concerned with the so - called basic shortest 2 - connected steiner networks, which was introduced by hsu and hu [ 16 ]. we give two new properties of basic shortest 2 - connected steiner networks and two sufficient conditions for shortest 2 - connected steiner networks to be basic
Hsu和hu在文獻[ 16 ]中引入了基本最短2 -連通steiner網路的概念，並且給出了它的幾個性質，在第三章中，我們對基本最短2 -連通steiner網路進行了進一步的研究，首先得到了基本最短2 -連通steiner網路的兩個新的性質，然後給出了基本最短2 -連通steiner網路的兩個充分條件。 -
And it also can not give the exact appearance place. aiming at this question, basing on studying the underground cavity in laxiwa hydroelectric station, through establishing entity model, combining model, slicing model, and vector analysis, article introduce a method of analyzing the stability of block and get the certain search. all the graph result is showed in autocad, which is a graph software
針對此問題，本文以拉西瓦水電站地下洞室為研究場所，以autocad圖形軟體為平臺，建立地下洞室和結構面的實體模型，通過對實體模型的組合、剖切獲取結構面的洞頂及洞壁展示圖，再以結構面展示圖為基礎，應用矢量運算對塊體進行穩定性分析，並在autocad中顯示結構面展示圖和塊體展示圖。
