But in the + moiety, the three benzimidazole rings shared the whole space equally, the dihedral angel among them is about 120°, just like three fan blades of an airscrew, the molecular structure appear gear-like shape.

X-射线单晶衍射测试、红外、紫外等方法确定了三(2-苯并咪唑亚甲基)胺的Fe和Co配合物的结构，由晶体结构发现金属配位情况不同、配合物在结构上存在着差异，Fe为八面体构型，而Co为三角双锥构型；其次，两配合物中的苯并咪唑环间夹角不同，配合物中包含N2和N4的两个苯并咪唑环间夹角仅为9.41(0.11)，几乎构成一个平面，呈蝴蝶形；后者Co三个苯并咪唑环几乎平分了整个空间，它们之间的夹角约为120，呈三扇叶螺旋桨式构型，为齿轮形。

These two things are what we will study in sectionⅢ. We call them GS and PS. In this section we will study the impact of the two and the relationship between them. Of course, there are some other ways to observe the problem. One of them is to consider the period and the distribution of eigenspace. These are what we will study in sectionⅡ.

这两方面也就是本文中第三章所讲的生成序列和扰动序列，这一章中我们主要研究了这两个因素对分数傅立叶变换算子的影响及它们之间的关系；当然还有另一种看问题的角度就是从算子的周期性和特征子空间的分布的角度，这就是第二章中所介绍的内容，在这里我们给出了两个三周期的分数傅立叶变换算子并比较了其特征性质。

The three states are transformed via two-dimension liquid crystal element and polarizators, and ternary arithmetic operation and ternary logic al calculus completed directly in this way.

三值光计算机用相互垂直的两个线偏振光和零光强三个独立的光状态表示信息；用二维液晶器件和偏振器实现此三个状态间的转换；采用三进制算术运算；直接处理三值逻辑运算；拥有巨大的数据位数(容易超过10~4位)；具有光运算、光传送、电控制等结构特色，具有很强的空间、时间并行性。

And in the second part, we consider the following four inverse eigenproblems: the reconstruction of normal five-diagonal matrix by two or three ordered eigenvalues and cor...

第二个部分则讨论四类矩阵逆特征值问题：在考虑给定的两个或三个特征值次序的情况下构造唯一的规范五对角线矩阵：由三个给定的特征值和相应特征向量来构造唯一的实对称三对角线矩阵和不可约实对称三对角线矩阵。

For the above purposes, using a tailored cyanometalate precursor,(1) Tp=hydrotris (pyrazolyl borate; Bu〓N〓=tetrabutylammonium cation , two trinulear complexes,〓(2),〓(3; cyclam: 1, 4, 8, 11-tetraazacyclotetradecane), two one-dimensional polymers,〓(4; dien: diethylenetriamine),〓(5), and a cluster 〓(6) have been synthesized and characterized structurally and magnetically.

基于上述研究热点，我们以修饰的氰基金属化合物(1)为构筑基元（Tp：三吡唑基氢硼烷，Bu〓N〓：四丁基铵离子），合成了两个杂三核化合物，〓(2)，〓（3；cyclam：1，4，8，11-四氮环十四烷），两个一维聚合物，〓（4；dien：二乙烯三胺），〓(5)，和一个十四核簇合物〓(6)。

Glycols (e.g., ethylene glycol, or antifreeze) contain two hydroxyl groups, glycerol three, and polyols three or more.

甘醇有两个羟基，丙三醇有三个羟基，多元醇则有三个或三个以上羟基。

In addition to creating zone of stability in the Moon's orbit in which to build permanent space habitats, the Lagrange librations points have a unique geometry, such that three of the points form an equilateral triangle and two of those three points form congruent equilateral triangles with the Earth and Moon.

此外，可以在月球的轨道创造稳定区域，来建立永久性的太空栖息地。拉格朗日点有一个独特的几何形状，例如有三个点（L3、L4、L5），形成等变三角形。而这三个点中又有两个（L4、L5），和地球月亮构成两个等边三角形。

For example, they say that the three matzahs represent the Trinity, with the broken one representing Jesus on the cross (in Judaism, the three matzahs represent the three Temples, two of which have been destroyed, and the third of which will be built when the moshiach comes).

例如，他们会说，这三个matzahs代表三一，随著打破一个代表耶稣基督在十字架上（犹太教，三matzahs代表三个庙宇，其中有两个已被销毁，以及第三场将於何时建成该moshiach来）。

Secondly, Implement "Three Represents", which is the essential demands for the Party to be "Two Vanguards".

要成为&两个先锋队&，党必须始终做到&三个代表&，实践&三个代表&是党成为&两个先锋队&的本质要求。

Meng Fei too much trouble to see scenarios, and would take his kids went to play with the game somewhere else and thought they were about to take classes love to run around to keep busy, especially depressed mood, see Yi Xi are now over, he tells her own thoughts, Huafeng Cheung do not know when the kids are standing in the middle Dou Zhe have fun, kicking Plum Star also ran along for the ride, hands clutching a davie home a baby, Yang Lan-Hui from the hands of hold on to Cai Yaping, letting Linger walked over holding Zhi-Qiang Zou, henny and jenny to david, respectively hold the other two kids amused to see two little devils exception difficult, Meng Fei Xi easy pick over, Huafeng Xiang begins with Linger Guo Zhi-Qiang Zou hold the hands of a few kids see so many people afraid of the Ku Chu the sound, immediately followed by the other two are also up crying, see posture is not good to stay at home two david did not cry in the side, the other three is sent to the hands of their parents, until there is no crying coax Douzhe.

孟菲看情景太闹了，就带着孩子们去了别的地方玩起了游戏，想到自己快要接love班东奔西跑不停忙碌着，心情格外郁闷，见易夕也跟了过来，便告诉她自己的心事，华丰翔不知什么时候也站在孩子们中间逗着大家玩乐，惹得李子星也跑过来凑热闹，手里还抱着davie家的一个宝宝，杨晓月从徐兰惠手中抱来蔡雅萍，又让灵儿抱着邹志强走了过来，henny和jenny分别抱来david其他两个孩子逗乐着，看两个小鬼异常吃力，孟菲和易夕接了过来，华丰翔便从灵儿手中抱过邹志强，几个小孩见人太多害怕着哭出了声音，紧接其他两个也跟着哭闹了起来，见架势不妙，就留david家两个没有哭的在身边，其他三都送到各自父母手中哄逗着直到没有了哭声。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
