图一 1。我们用汉斯酯作为有机还原剂，乙醇为溶剂，实现了4-甲叉基噁嗯唑酮和吡唑酮环外双键的高选择性还原；此外，我们还将这一还原体系用于3-吸电子集团取代-3，4-二氢香豆素环内双键的选择性还原。

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。

Compared of the efficiency of treating heavy metals in FGD wastewater with NaOH, Ca_2 and Mg_2. It indicated that NaOH was much efficient for precipitated waste water; Ca_2 was much efficient for unprecipitated waste water, the removal efficiency reached 98.4%. With the increasing of the main ion of Ca~2+, Cl~- in FGD wastewater, the efficiency decreased. It decreased 60% for the removing of Mn and 10% for Zn, Cd and Ni. The rectification coefficient token the Ksp of practical wastewater because it quite different with theoretic Ksp at different pH; the theoretic and practice addition were proportioned and it commonly reached 1:300.The precipitation efficiency of Na2S at different pH and the effect of Ca2+ was determined.

比较了NaOH、Ca_2和Mg_2处理脱硫废水时重金属的去除效果，分析了Ca~(2+)、SO_4~(2-)和Cl~-等主要离子的影响，结果表明：NaOH和Ca_2能有效处理脱硫废水中的重金属；对澄清废水而言，NaOH效果较好，对于未澄清废水而言，Ca_2效果更好，但去除废水中重金属的效率都能达到98.4%；随着Ca~(2+)、Cl~-等主要离子浓度的增大，中和作用去除重金属的效率降低，Mn最大降低60%，Zn，Cd，Ni降低10%左右；实际重金属浓度和用理论Ksp计算所得值差别很大，通过校正系数能有效计算实际重金属浓度；实现相同pH时氢氧化物的理论和实际投加量成一定比例，最大可达1：500。
