构

For example, if a graph has exactly one cycle, then all graphs in its isomorphism class also have exactly one cycle.

"这一概念图同构"使我们能够区分图形性能固有的结构图自己从性能与图申述：图图，数据结构的图形，图表标号等例如，如果一个图，正是一个周期，然后在其所有图形类也有同构的一个周期。

Graph isomorphism problem is one of the problems that have not been classified as NP complete, or within P.

根据图同构国内外目前的研究进展，图同构既未被归入P问题，也未被归入NPC问题，是一个尚未解决的问题，有待进一步研究。

A novel method,the circuit simulation algorithm,is proposed here,whichtransfers the graph isomorphism problem into the identical circuits problem.

提出了一种新的同构判定算法：电路模拟法，即将图的同构问题转化为电路的相同问题。

图同构； NP问题； P问题； NPC问题；图同构完备

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。

The concept is simple but it's not so easy to determine whether two graphs are isomorphism or not.

同构的概念看似简单，但是，判定两个图同构却不是一件简单的事情。

At the same time, isomorphism for many special classes of graphs can be solved in polynomial time, and in practice graph isomorphism can often be solved efficiently.

与此同时，同构为许多特殊类别的图形就可以解决在多项式时间内，并在实践中图同构，往往可以有效地解决。

The superstructure has used the model of elastical constitutive relation; the pile-group foundation has quoted the soil-pile equivalent compound model. It has been analyzed the constitutive relation for soil-pile equivalent compound which regarded as the transversely isotropic body this construction relations, and determined the corresponding elastic constant.

上部结构采用线弹性本构模型，下部群桩基础引用了桩土等效复合体模型，分析了将桩土等效复合体视为横观各向同性体的本构关系，确定了相应的弹性常数。

In my paper, under the aesthetic principle of uncertainty ,I analyse the features of Barthelme's works on two aspects: game and carnivalization, with the French philosopher Jacque Derrida's major destructive key words and the Ruassian philosopher Bakhtin's theory.

本论文从巴塞尔姆不确定性的美学原则入手，以德里达的解构主义和巴赫金的狂欢化理论为指导，从两方面探讨了巴塞尔姆作品的特点：结合延异、播撒、擦抹等解构策略分析了巴塞尔姆小说的游戏性；从狂欢化角度切入作品的艺术思维、美学风格、修辞、语言等几方面，探讨了他作品的狂欢化美学风格。

Molecular configurations in LB films undergo change from keto form to zwitterion assurface pressures increase,companied by intermolecular hydrogen bonds decreaseand intramolecular hydrogen bonds increase.

在LB膜中，随表面压增加，分子间氢键减少，分子内氢键增加，SBC18头基构型在转折区发生醌式→双性离子构型转变。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
