The research of the thesis can be divided into four parts:Part one. The cheap raw materials, such as soluble glass, HCl, MAA were used as reactant. A aggregation SiO2 powder with network-type was prepared by controlling the ratio of material, temperature, time, mixing speed, which has smaller size than that of products sold in the market.

本论文研究工作分为四个部分：第一部分：采用价廉的水玻璃和HCL、MAA、CO2酸化体系为原料，通过材料配比、制备温度、时间、搅拌速度等工艺条件的研究，制备出比市场上销售的二氧化硅粒径更小的呈网络附聚体形态的SiO2粉体。

On the functional differentiation,we found and that the type II ras-GTPaseactivating protein (p100-GAP),which was specifically expressed in humanplacenta,was largely expressed in the highly-differentiated syncytiotrophoblastcells and moderately expressed in the cultured intermediate trophoblast cells.While in the non-differentiated cytotrophoblast cell line-NPC,no expression was observed.Its mRNA and protein expressingcharacterization was in consistent with that of hCGβ,which was one of the mostimportant markers of the trophoblast cell functional differentiation.In addition,the expressing amount of p100-GAP increased with the progressing of pregnancyand the syncytium formation in vitro.

细胞功能分化的研究结果表明：经重组质粒的构建获得特异表达于人胎盘的p100－GAP的cDNA探针后，从蛋白和分子水平证实p100－GAP大量表达于分化程度高的合体滋养层细胞，少量表达于体外培养的中间型滋养层细胞，而非分化的细胞滋养层细胞NPC则不表达，这种表达特性与作为滋养层细胞功能分化重要指标之一的hCGβ高度一致；p100-GAP表达量还随妊娠过程和体外合体化过程而逐渐增加。

The result showed that during mitotic division, the Ser-10 phosphorylated histone H3 start from the prophase and vanished at telophase, remaining mainly in the pericentromeric regions at metaphase and anaphase. During the mitosis the microtubules take on regulated change pattern.

结果显示在小麦根尖细胞有丝分裂过程中Ser10磷酸化的组蛋白H3的出现和消失与染色体的凝集和解凝集的过程存在时空上的相关性，在有丝分裂的过程中这种蛋白在着经线粒上的定位有有助于染色体向两极移动。

It was shown from the results that emulsifier TP-Ⅴ which was prepared by PEG 4000 reacted with TME, in the molar ratio of TME to PEG 2:1, at about 110℃ for 1 h, catalyzed by boron trifluoride diethyl etherate, has a very good emulsifying impact for TME. Particle size distribution of the emulsion was homo-geneous and viscosity of the emulsion was small.
