In this thesis, the concentration of graphite powder in the liquid nickel sulfamate and current density are chosen as parameters for composite electrodeposition of nickel and graphite powder. In addition, after electrodepositing, the graphite powder is oxidized into carbon dioxide through heating process for obtaining porous structure. Filter devices of various specifications can be made by controlling the hole dimension of the porous structure.

本研究为了制作出多孔洞结构，将在氨基磺酸镍电铸液中以不同的石墨粉浓度及电流密度为参数进行复合电铸，并且经由加热处理使石墨氧化成为二氧化碳以制造出多孔结构，根据这些多孔结构的孔径大小可以获得各种规格的过滤结构元件。

Structural magnetic resonance imaging include lineal mesure, volume measure and volume rendered. They can detect the abnormal brain structure, especially the change of mesial temporal lobe in early onset of Alzheimer s disease. Recent studies more focused on functional imaging which can find the functional changes in brain. Prior to structural changes, functional changes happen, so it can reflect the sutile pathological process in Alzheimer s disease.

磁共振成像结构影像学主要介绍了磁共振成像线性和面积测量、磁共振成像体积测量和磁共振容积再现三方面，其研究热点主要集中于阿尔茨海默病患者异常脑结构的分布，以及特征性结构内侧颞叶，尤其是海马，杏仁核，以及内嗅皮质在结构在阿尔茨海默病早期诊断治疗中的作用。

The Stacker-reclaimer system has the tanglesome steel frame structure, therefore the guarantee the anti- pulled and anti- pressed intensity of the structure and the equipment distortion is precondition to improve on the structure of the equipment .

Marsh made important contributions to it later. Titman and Wessels combined the capital structure influence factor theory with the pecking order theory until it became part of the mainstream capital structure theory.

Titman和Wessels把资本结构影响因素理论与Myers等人的优序融资理论结合起来，既用优序融资理论来支撑资本结构影响因素理论，又用资本结构影响因素理论来印证优序融资理论，这才把这个非主流理论融入到资本结构的主流理论里。

Toxicologic tests show it has no side effectcs,whichhas been appraised by specialists.It is proven to be effec2tive in treating hepatitis B,hepatitis C,acute and chronichepatitises,and some other liver diseases.

有人认为，在英语广告中，主动结构使用多，被动结构使用少，这是因为被动结构往往会使人产生自己处于被动地位，……，而主动结构则可使人们认为自己处于主动的地位，……，而不是被动地去做自己不愿做的事情。

The results show that both norbornenic and cyclopentenic double bonds are involved in the polymerization. The propagation on the NB double bond generates structural unit I by direct addition and unit II by carbocation rearrangement, respectively. Similarly, the propagation on the CP double bond produces structural unit III by direct addition and unit IV by transannular rearrangement, respectively.

结果表明， DCPD分子的降冰片烯双键和环戊烯双键均参与了聚合反应并根据不同链增长机理产生四种链结构单元：通过NB双键的链增长反应可生成直接加成结构单元I和重排结构单元II，通过CP双键的链增长反应生成直接加成结构单元III和跨环重排单元IV。

Treatment at a high temperature would bring big changes to the structures of titanate nanotubes. When the calcination temperature was higher than 450℃, the tubulous structure of titanate nanotubes was destroyed and transformed into anatase phase.

高温煅烧处理对钛酸盐纳米管的结构影响较大，当温度高于450 ℃后，纳米管的层状结构被破坏，晶体结构转化为锐钛矿相的TiO2结构。

Presents the microstructure evolution in aluminum a nd copper after deformation by cold rolling in the strain range of 10 to 50%red uction using TEM and points out three types of dislocation structures are typica l and two of them are common for both materials and these two common types are f ound in non-cube grains and can be distinguished by crystallographic orientatio n of dislocation boundaries in the grains and the third type of structure is obs erved in cube grains, and concludes that grain orientation is important in deter mining the structure type but some other metallurgical parameters also have a ro le to play.

采用TEM对冷轧多晶铜与多晶铝的形变显微组织演变进行了对比研究。结果发现：多晶铜及多晶铝形变显微组织中均含有三类典型的位错结构类型，其中的两种结构特征在两种材料中是相似的，这两种类型结构存在于非立方取向晶粒，可通过晶粒中位错边界的晶体学取向加以区别，另一类型结构存在于立方取向晶粒；晶粒的晶体学取向决定了其形变显微组织类型，但其它冶金学因素对显微组织也有影响。
