Al impurity, the floatabilities of hematite and aegirine were resemble, which is contributed to the existence of structrual iron ion on surfaces of both minerals. It is the structrual iron ion that accelerates the floatability of aegirine greatly and leads to difficult separation with hematite. 2. The basic mechanism of actions of fluorosilicate salts as selective depressants of aegirine during the direct flotation of hematite was investaged detaily by using FTIR and XPS spectrocppy, fluorosilicate salts are poor depressants for hematite, but are very strong depressants for iron-containing silicate such as aegrine in weakly acid medium, which can enlarge the flotation differences between two minerals.

运用X射线衍射、俄歇能谱等测试手段研究了赤铁矿与钠辉石纯矿物的晶体结构特征，表面破裂面的元素组成与赋存状态，发现在白云鄂博不同的矿床（氧化矿段，原生矿段，风化矿段）存在着三种颜色与可浮性均有所差别的钠辉石，其可浮性的差异主要是由于表面含铁量及Ca、Al等杂质含量的不同而引起的，结构Fe〓的存在导致钠辉石可浮性剧增从而与赤铁矿难以分离。

Secondary feldspar was related to the albitization process of feldspar, the albitization of plagioclase began at the early stage of diagenesis, and the albi.

次生长石与长石的钠长石化过程有关，斜长石钠长石化始于成岩早期，而钾长石的钠长石化则需较高的成岩条件才能进行。

Sodium 2-Acrylarnido-Acetate has been synthesized through the reaction of Aminoacetic acid with acryloyl chlorine, then Copolymer of sodium 2-acrylamido-acetate and dimethyl diallyl ammonium chloride with acrylamide had been prepared by free radical polymerization using (NH4)2S2O8 and NaHSO3 as the free radical initiator in water solution.

本论文首先以氨基乙酸和丙烯酰氯为原料制备丙烯酰胺基乙酸钠单体，然后以丙烯院胺丙烯酰胺基乙酸钠和二甲基二烯丙基氯化铵为单体，(NH4)2S2O8和NaHSO3为自由基引发剂，采用水溶液聚合法合成丙烯酰胺／丙烯既胺基乙酸钠／二甲基二烯丙基氯化铵共聚物。

In order to overcome the fault of 5'-GMPNa2 product quality, such as amorphic state, lower purity and inconstant water content, a systematical study on the crystallization process of 5'-GMPNa2 had been presented in this thesis. A new crystallization process has been developed, with which the high quality crystals of 5'-GMPNa2 can be obtained.

针对目前国内生产5'-鸟苷酸二钠基本为无定形体，且产品纯度低、水含量不稳定等问题，本文对5'-鸟苷酸二钠的结晶过程进行了系统的研究，提出了新型精制结晶工艺，解决了制备高质量的I型5'-鸟苷酸二钠晶体的问题。

Aiming at the shortcoming of sodium sulfantimonate preparation process,a new preparation process was designed which adopted sodium sulfide to leach sodium sulfantimonate from sodium antimonate.

针对目前硫代锑酸钠制备工艺的不足，设计出用硫化钠浸出锑酸钠制备硫代锑酸钠的新工艺。

objective to observe the effect of unithiol for the treatment of arsenic apicitis.methods sixty-three patients received therapy with 5% unithiol and the therapeutic effect was retrospectively analyzed.results 59 of 63 teeth were cured with the cure rate 92%; no effect was observed in 4 cases.conclusion unithiol can be effectively used for the treatment of arsenic apicitis.

目的 观察二巯基丙磺酸钠治疗砷性根尖炎的疗效。方法 63例患者患牙63颗接受5%二巯基丙磺酸钠治疗，回顾分析其疗效。结果 63颗患牙经本药治疗后59颗显效，占93.7%；4颗无效。结论二巯基丙磺酸钠可有效并安全用于治疗砷性根尖炎。
