electrical networks; concepts related to topology of electrical networks and theory of graphs 電網(wǎng).與電網(wǎng)拓?fù)鋵W(xué)和曲線圖解原理有關(guān)的概念
the theory of graphs can be roughly partitioned into two branches : the areas of undirected graphs and directed graphs ( digraphs ) 圖論大致可分為兩個(gè)方向:無(wú)向圖與有向圖。
a new algorithm based on the minimum spanning tree theory of graph was proposed which improved the computation efficiency and reliability of previous methods . 2 對(duì)基于圖的最小生成樹理論的算法進(jìn)行了改進(jìn),新算法在效率和可靠性方面都有所提高;2
based on these achievements, this paper mainly considers the stability of networks with neighbor condition . some results are obtained, therefore the stability theory of graphs are enriched in some extent 本文在前人工作的基礎(chǔ)上,著重研究了鄰域場(chǎng)合下圖的穩(wěn)定性,得到一些相關(guān)結(jié)果,在一定程度上豐富了已有圖的穩(wěn)定性理論。
based on the research and analysis of information of assembly of product, semantic of assembly is divided into four types in order that assembly mode is expressed briefly and definitely . assembly mode of product is described through graph of assembly semantic by the way of the theory of graph 在產(chǎn)品裝配關(guān)系深入研究和分析的基礎(chǔ)上,為使產(chǎn)品裝配模型信息表達(dá)簡(jiǎn)潔、意義明確,將裝配關(guān)系分成4種基本類別,采用圖論方法對(duì)產(chǎn)品的裝配模型進(jìn)行圖的表達(dá)。
