The characters of powder are connected with the inside structure and synthesize-technics of materials. In this paper, we want to search a optimize technics of materials synthesizing, and prepare a kind of nanosize powder which shape like ball and have good dispersed character. At the same time, we want to obtain a bridge structure of Zn-O-Tb through dopping of Tb, which can achieve efficient energy transfer from ZnO hosts to excited states of dopants, The doped powder can eradiate blazing green light because of efficient emission buildup from dopants and ZnO hosts, and the powder can emission a pure light. And we want to research the structure in doped ZnO for the further research of low-tension fluorescence of ZnO.

粉体的这些特性无不与其内部结构特征和制备工艺有关，基于这些，本文的实验目的是希望能寻找一种合适的制备方法和优化工艺，制备分散性好的球形纳米颗粒，希望改善其表面形貌，同时，通过铽掺杂，希望得到一种Zn-O-Tb桥联结构，实现氧化锌基体向铽发光中心的能量传递，希望铽中心特征发射和氧化锌绿光发射能有效叠加增强，改善粉体的单色性，制备出好的复合粉体，分析清楚其结构，从而为后续低压荧光特性研究作准备。

The beads can be spherical or chips or faceted in nature as long as they are not dyed.

The results showed that various morphologies of barite particles, such as flowerlike aggregates, spheres, rod-like superstructures etc. could be synthesized by changing the concentration of PSMA, pH value of solution, and molar ratio of Ba~(2+) to SO_4~(2-).

结果显示，通过改变PSMA的浓度、溶液的pH值、溶液中钡离子与硫酸根离子的相对比例R等实验条件能够合成各种形貌的硫酸钡颗粒诸如花形片状团聚体、球形、棒状超结构等。

Seepage mechanism is applied to deduce two kinds of osmotic grouting model (plane radial flow and ball-type centripetal flow). Security grade basic working condition and reliability index of grouting on sand-fixed is proposed. And formulize reliability analysis of grouting on sand-fixed combining engineering cases. 4. The mechanism of sand-fixed of grouting engineering and sand-fixed of biological engineering is described.
