In the hypothesis, it is assumed that the photoreceptor outer segment is a cylindrical-like structure, while a photo enters the outer segment, the possibility of the impact between the photon and a photopigment molecule is maximal if the photon's travel path parallels to the axis of the cyclinder.

其理论系假设光感细胞的外节为一圆柱状结构，当光子进入到光感细胞的外节部分时，若其路径与此柱状结构的轴向平行，其碰撞到光色素分子的机率会最高，因此所产生的响应将最大。

Scalariform thickening A type of secondary wall formation consisting of interlaced helical bands of thickening giving a ladderlike formation. It allows for very little further extension, and is found in tissues such as metaxylem tracheids and vessels, which do not elongate after maturation.

梯纹加厚：是植物细胞次生壁的一种形态结构，壁由加厚过程中相互交错成梯状形态的螺旋带形成，其可延伸性很小，多存在于后生木质部管胞和导管等一些成熟后便不再延伸的管状分子中。

Objective In order to make a foundation for molecular diagnosis and gene engineering studies of Avian encephalomyelitis virus, the structural protein VP3 gene of AEV and expression of its recombinant protein were cloned and sequenced.

目的对VP3进行克隆和测序后，在杆状病毒系统中表达获得重组蛋白，为AEV的分子诊断以及更深一层次的分子和基因工程研究打下基础。

Such one-dimensional chains interconnect via hydrogen bonding and π-π interaction to form an extended undulated sheet-like structure.

经配体桥联的两个金属离子的距离是6.703〓。这样的一维链通过配体的NH部分〓Cl及溶剂分子甲醇相互之间形成的氢键连接扩展成二维波浪状结构。甲醇分子被包容在层间。

Its hydrophilic groups is the inside carbonyl and amine base, and its lipophilic groups is the inside hydrocarbon chain and outer methyl. PAMAM of integral generation basically has not the surface activity. Its reason is that its outer groups is acylamino groups having very strong hydrophilicity so as not to reduce the surface tension of water. PAMAM different from traditional surfactant, have not critical micelle concentration, and exist in the form of "unimolecule micelle" in water.

结果表明：半代的PAMAM水溶液的表面活性与其分子具有两亲结构有关，亲水基团是内部的羰基和胺基，亲油基团是内部的碳氢链和外层的甲基；整代的PAMAM水溶液基本上没有表面活性，其原因是其最外层基团是酰胺基，亲水性很强，不能降低水的表面张力；树状大分子与传统的表面活性剂不同，不存在临界胶束浓度，在水中是以&单分子胶束&形式存在。

Synthesis and liquid crystalline behavior of three recently reported mesogenic block-molecules, namely polyhydroxy 1-benzoylaminopropane-2,3-diols I、star-shaped pentaerythritol tetrabenzoates II and calamitic bolaamphiphiles with lateral chains III which are constituted of anisometric block, amphiphilic block and alkyl or perfluorinated chains with different topologies are reviewed in this article.

The results show that the conformation of copolymer molecules is totally different from that of carboxy methyl cellulose because of the introduction of the surface active macromonomers.

结果表明，共聚物在水溶液中的形态完全不同于羧甲基纤维素分子，亲水疏水链段的引入，使共聚物分子聚集形成了以疏水链段为核心的棍状胶束结构。

The copper center was situated in a distorted square pyramidal (4+1) CuN3X2 coordination geometry with terpyridine acting as an equatorial tridentate ligand.

在配合物中，中心铜原子的配位环境为变形四为锥，并通过分子内和分子间的C-H…C1和C-H…O氢键作用形成三维梯状结构。

We adopt a similar discotic liquid crystalline synthesis way to synthesize target molecules 7, 11, 15, 19, 21 in this article. The target molecules have a central triphenylene core and different side chains including triphenylamine derivatives and carbazole molecules. We observe these molecules optical and electrochemical properties and the effect of hole-transport layers in organic light emitting diode.

本篇论文的研究主旨是采用类似盘状液晶的合成方式，以三伸苯作为分子的核心，藉由改变不同的三苯胺及咔唑醚基侧链来合成目标化合物7、11、15、19、21，并观察分子的光学性质变化，电化学行为，以及作为电洞传输材料在有机电激发光元件上的效果。

Shape of fluorescence spectrum of diphenylanthracene in multilayer film is almost the same as that in solution, and the position of emission peak does not show apparent shift, which is related to the fact that fluorophore are surrounded by highly branched dendrons. These results provide a new route for design and assembly of luminescent materials.

溶液中的荧光光谱和多层膜的荧光光谱的形状和峰位都非常接近，这和发色团处在树状分子的三维支化结构的中心是直接相关的，这一研究对发光材料的分子设计具有重要的指导意义。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
