模群

It proves that the first cohomology group of Block Lie algebraL with coefficients inL-module V is trivial.

证明了系数在模V上的Block型李代数的一阶上同调群是平凡的。

The paper first obtains the L2 -apriori estimates for the solutions of two kinds of autocatalytic model s under Dirichlet boundary conditions, and then, using the properties of linear semigroup and delicate calculations, the estimates of the maximal norms are obtained, therefore, the global existence of the solutions is proved.

该文利用重要不等式及能量积分方法首先得到了解的初等的先验估计。然后利用线性半群的有关性质及精细计算得到了解的最大模估计，从而证明了两类三次自催化模型在Dirichlet边界条件下整体解的存在性，并进而证明了第一类模型的最大吸引子的存在性

The two side buildings are the imitation of the Palace of Fontainebleau of France.

建筑面积24，000平方米，由一座主城堡和两座城堡式配楼组成，主城堡由法国设计师参照法国十大贵族城堡之一的"拉斐特城堡"为模型设计，再现欧洲后文艺复兴时期巴洛克式建筑风格，主城堡前是一片布局独特的法国公爵式模纹花坛，栩栩如生的古希腊神话雕塑群置于其中。

The group velocity dispersion properties of photonic crystal fiber were investigated in detail by equivalent index model.

应用等效折射率模型对折射率导模光子晶体光纤的群速度色散特性进行了详细的讨论。

The results of PMD value by numerical simulation are similar to that estimated by Jones matrix when differential group delay is less than a bit period.

将模拟得到的偏振模色散大小与从琼斯矩阵理论中计算的结果进行比较，结果表明，采用该模型的模拟结果与理论计算值在差分群时延为一个比特周期内符合较好。

Note that when the modulus of the group is a prime, we have G =.

注意，如果群的模是素数，我们就有G =。

The pajama-striped, shawl-collared suit that opened the show comfortably established the manifesto: no shirt, just a scarf. Even given the exaggeration one allows the catwalk, Dolce and Gabbana were clearly onto something. Chic-but-comfy is the grail of enough guys that the combination of tailoring and trackies should spell ka-ching. And it's not just guys—Naomi Campbell looked gorgeously natural in the grand finale of Orientalia in her flowing kimono, shorts, and ballet flats. BTW, each of those closing outfits was arduously hand-inked: There's a new challenge for your dry cleaner.

同时，与男仕同款图案的女性睡袍衣衫也点缀的在这群精壮迷人的男模中：Naomi Campbell一袭日式和服风格罩袍与抽绳boxer下搭平底芭蕾舞鞋样式便鞋，营造出无远弗届的完全性感；要特别注意的是，这一系列东方花鸟虫鱼图案的休闲单品可是相当精致的手工印染，也同时挑战著你的乾洗衣店师傅的专业功力。

The sufficient and necessary conditions which Fuzzy subalgebra of direct product Boolean algebra can be decomposed as direct product of two Fuzzy subalgebras are obtained.

进而分别定义了在对偶模意义下直觉模糊群的外直积与内直积。

Methods A stratified random cluster sample of 17269 students in China were investigated with the children and adolescents' QOL scale according to the census data in 2000, and the urban and country norm of the scale were respectively established.

依据2005年第5次全国人口普查资料，在全国进行多阶段分层整群抽样，分别建立城市和农村2套常模。

It is found that for a certain mode-locked solid-state laser with a pulse profile of sech2(1.763t/τ),the jitter is approximatively a linear function of the net group delay dispersion,and turns to be larger with increasing GDD ;however,it cannot be reduced to zero even if the GDD is completely compensated.

结果表明：对于一台脉冲轮廓为sech2(1.763t/τ)的确定的锁模固态激光系统，时基抖动近似为净群速延迟色散的线性函数，且随着GDD的增加而变大；然而，即便在GDD被完全补偿的情况下，时基抖动也不会是零。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
