With the sedimentary index as a basis, combined with seismic phases and well logging phases, an analysis has recognized that conglomeratic Zheng-408 sand body is a near-origin, faster deposited, fan-delta facies conglomeratic sand bodies, with later low maturation in both composition of structure and weak diagenesis.

以沉积学标志为基础，结合测井相及地震相等方法，分析认为郑408砂砾岩体为近源快速堆积的扇三角洲相砂砾岩体，成分成熟度和结构成熟度都低，成岩作用弱，以原生孔隙为主。

ABSTRACT In this paper, by employing dicarboxylic acids with special conformation, i.

利用几个结构上有特点的二元羧酸，即2，6-吡啶二甲酸、三个异构体苯二甲酸，顺丁烯二酸和4，4'-联苯甲酸作为首要桥基配体，并结合使用含氮中性配。。。

Access to the catalytic center and an unusual switch I movement in the dimeric structure support this finding.

二聚体中催化中心的入口和一种不寻常的开关运动支持了这一猜想，即易位子复合物之间的相互作用或蛋白质前体的潜在结合位点都是由这种二聚体的结构特点决定的。

SDS-PAGE showed that fusion proteins had a disulfide-bonded dimeric structure and existed as homodimer.

SDS-PAGE结果显示该蛋白具有通过二硫键结合的二聚体结构并以同源二聚体的形式存在。

Many structural deficiencies and mistakes were highlighted, which including excessive horizontal displacement in the ground, more severe damaged transition layer (the first masonry structure layer), ground with farraginous structure, and poor construction quality. Finally, lateral stiffness ratio of the second to ground story in masonry buildings with RC frame structure at the bottom will be optimized following difference of materials between the ground floor and the upper floors. The strength and the ductility of transition layer, as well as shear walls in the ground floor, are crucial to keep the building standing during large earthquake.

在介绍和总结了汶川地震中底框砖房的表现―底层过大的水平侧移、过渡层严重破坏或完全坍塌、底层严重破坏或房屋完全倒塌、上部砌体整体发生侧移、以及设计一和施工质量良好的底层抗震墙砖房&大震不倒&的基础上，得出以下结论和建议：在抗震设防地区应禁止使用部分底框砖房，地震中过渡层的实际受力情况与设计所采用的受力状态有明显的区别，规范应考虑砌体和钢筋混凝土材料的不同力学性质来制定上下层刚度比要求，明确对过渡层的延性和强度要求，明确该类结构抗震概念设计的具体措施。

Polysaccharides from wild tetraspotophytic and female gametic thalli of Gracilaria lemaneiformis (denoted as TP and FGP respectively) were extracted with hot water and a comparative study was made on their chemical characteristics and structures.

According to the effect of guanylic acid on fluorescence intensity of ligand-Cu or Fe (Ⅲ binary complex system, it is found that guanylic acid and Cu, Fe have synergic quenching effect on the fluorescence of ligand due to the formation of ternary complex.

对原始配体CPFX进行了元素分析、FT-IR、〓H-NMR、〓C-NMR、MS等手段进行了结构确证，并讨论产生这种变化的可能过程，对配合物配体间的相互作用（氢键作用、芳环堆积作用）着重进行了讨论。

Results: No fiber layer and inflammatory tissues around any inserted implants were founded. New-grown osteoid tissue appeared faster in Bio-Ti implants than pure titanium and matured bone tissues comprise bone trabecula and Haversian canals appeared in 6 weeks, while at least 12 weeks needed to form matured bone tissue in control groups.

结果：所有种植体周围没有发现明显炎症组织或形成纤维层，Bio-Ti种植体组新生类骨组织生长较快，并于6w时已形成含有骨小梁及哈弗氏小管结构的较成熟骨组织，对照组12w时新生骨组织基本成熟。

Functional ASICs are usually believed to be tetrameric assemblies of homomeric or heteromeric subunits.However,recent Gouaux and colleagues crystal structure shows that there are three subunits in ASIC1 homomeric channel.

功能性的ASICs通常被认为是由相同或不同的亚单位形成的四聚体，然而最近Gouaux等的晶体结构研究表明ASIC1同聚体由三个亚单位装配而成。

A variety of ordered bulk phases, including lamellae, hexagonally packed cylinders, body-centered-cubic spheres, and a bicontinuous network structure called Gyroid are observed for diblock copolymers.
