We find serval conditions that are equivalent to 2-tournament matrices being singular,give the bound for the maximum algebraic multiplicity of 0 as an eigenvaulle of n order2-tournament,obtion the spectral radius of a singular 2-tournament matrix of order nis bounded above by n-2,and investigate 2-tournament matrix achieving this bound.

第五章讨论了2-竞赛矩阵的奇异性和特征值之间的关系，得到了2-竞赛矩阵奇异的充要条件，给出了2-竞赛矩阵的零化向量的刻划，得到了得分向量，3-圈数目与奇异性的关系；给出了2-竞赛矩阵的特征值0的代数重数的上下界，得到了奇异的2-竞赛矩阵谱根的最大值及谱根达到最大值的竞赛矩阵的得分向量的特征。

The background of the sword is black, whose surface is bestrewn with silvery white multi-cycle and multi-line patterns. All of them are made of plane and natural patterns. Though pictures can be taken for them, they are not to he made into rubbings. They do not lack ease and grace, but they are still subjected to certain rules.

该剑底色青黑，其上满布银白色重圈纹和组丝纹；它们都是平面花纹、自然花纹；看得见，难触摸；可摄影，不可拓摩；既自然流畅，又有一定规则。

This result is a common generalization of atheorem of Posa and a theorem of Bondy et al on the existence of heavy cyclesin weighted graphs under the same condition.

这推广了Bondy等人关于赋权图中最重圈的一个结论，也推广了Pósa的在非赋权图中有关最长圈的一个定理。

The inconsistencies of dimensional reduction and naive dimensional regularization in dealing withChern-Simons-matter theory are analyzed.The consistent dimensional regularization combiningwith higher covariant derivative regularization is adopted to consider Chern-Simons field theorycoupled to complex scalar and spinor field.All the local parts of one-loop two-point functionsand three-point functions are computed.Slavnov-Taylor identity is combined with these explicitcalculation results to give the one-loop local effective action.The finite gauge invariant quantumcorrection is shown and finite wave function renormalization constant for each field is defined.Thelocal part of one-loop three gauge field vertex is especially evaluated and it is verified that thereexists a renormalization choice compatible with BRST symmetry.

然后计算了所有的两点函数和三点函数单圈修正的定域部分，利用S-T恒等式给出了单圈定域有效作用量，定义了场的重正化常数，发现物质场和规范场都存在有限的规范不变的量子修正，并讨论了这些有限的规范不变的量子修正的物理意义，进而通过考察单圈三规范场顶角，表明存在与BRST对称性相容的重正化选择。5、在背景场方法的框架下，选择高阶协变导数正规化与维数正规化的杂化正规化方案计算了背景场两点函数的两圈量子修正，结果表明，标志紫外发散的极点项恰好抵消；进一步利用背景场方法中明显的规范对称性，证明背景场三点函数的两圈图贡献也是有限的。

It also had a hooded front iron sight in addition to the heavy barrel.

除了重的枪管之外，它还具有一个有护圈的的金属准星。

Even though the car was heavy, it was one of my best first laps this season.

尽管赛车很重，但这是我本赛季以来最出色的第一圈。

One is theexplicit formula for strict-connected acyclic hypergraphs:〓where a=r-d,m=/a;the other is the recurrence formula for linearacyclic hypergraphs:〓where the numbers of r-1 and r in the multinomial coefficient are j and krespectively,〓 and 〓.

一个是关于严格-维连通无圈超图的显式公式：〓其中a=r-d，m=/a；另一个是线形无圈超图的递推公式：1=〓其中r-1与r在多重组合数中的重数分别是j与k，〓且f(0，r)=1。

The city changed a climax to come, should avoid to encircle ground motion again, barytic, heavy city does not weigh city, small town old strategy, put through big question.

城市化高潮来了，应避免再来一次圈地运动，重土、重城不重市，把小城市大战略，搞成了大问题。

A special tribe called Kayan is known for wearing rings around their neck. Kayan women often say that their purpose for wearing the rings is cultural identity. The rings are rarely removed since they started wearing them around the age of five. The coiling and uncoiling is a long procedure. They are usually only removed to be replaced by a new or longer set of coils. To set the record straight, women do not suffocate if the rings are removed, though the muscles covered by them are weakened. Many women have removed the rings for medical examinations. Contrary to popular belief, the neck is not actually lengthened. Each coil is replaced with longer coils as the weight of the brass pushes the collar bone down and compresses the rib cage.

在清迈有一个少数民族称做Kayan族，当时为了逃难而来到泰国西北边界的媚洪顺，后来不知为何这支民族的妇女认为长颈才能显示出女人的美丽，因此她们从5岁起就在母亲的协助下在颈子上架起了铜圈，到了10岁开始每年再多加一圈直到25岁为止，到了25岁这些铜圈更可高达25圈重达5至10公斤；铜容易生绿锈，要时常擦拭，而且铜很沉，会将肩膀压塌，所谓的长颈并不是因为颈子变长，而是因为钢圈的重量长期压住锁骨和肋骨，使得脖子看起来变长了。

Based on the detailed study of seismic tomography image in South China, and according to the geotectonic environment and shape and heat of asthenosphere upwelling, we divided the structure of lithosphereasthenosphere at the Mesozoic upper mantle of Eastern China into three types.(1)Continental platform area (North China platform and Yangtze platform): asthenosphere upwelled along paleorift; over the plume head, the granitic rocks of crust and mantle mixed and correspondingly, Au, Cu, Mo, PbZn, etc. mineralizationconcentrated regions were formed; and at the steep contact belt of asthenosphere and the thick area of lithosphere, mediatebasic complex was formed.(2)Central area of fold zone: asthenosphere was "recumbent" at suitable depth, with adequate heat and in a great extent; by heat conduction, the interior of partial crust remelted, and the crustsource granitic rocks, and correspondingly, W, Sn and rare elements mineralizationconcentrated regions were formed.

在深入研究华南地震层析成像的基础上，按照大地构造环境和软流圈上涌形状和热度，将中国东部中生代上地幔中岩石圈软流圈构造划分为3类：(1)陆台区，软流圈沿古裂陷上涌，其柱头上方形成幔壳混熔花岗质岩及相应Au、Cu、Mo、PbZn等矿集区，并于软流圈与岩石圈厚区之陡接触带形成中基性杂岩及相应Fe矿集区；(2)褶皱带中心区，软流圈在适当深度、热量充足、较大范围内&平卧&，因热传导而致使地壳内物质部分重熔，形成壳源型花岗质岩及相应的W、Sn、稀有元素矿集区；(3)褶皱带边缘区(大兴安岭南部及华南南缘)，在软流圈上涌柱上方形成幔源或幔壳混熔的花岗质岩，相应为Cu、Au、PbZn、Mo、Ag矿集区。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
