Research on the solution chemistry of Al-V-Mo system in aquous solutionAccording to the calculation of solution chemistry,the solubility and existing status of Al,V and Mo in acidic and alkalic solution had been analysed in theory.The concentration logarithmic diagram of Al-V-Mo in aquous solution with different concentration and pH had been plotted,the concentration and pH on the distribution of three elements had been analysed.

铝、钒、钼水溶液化学性质的研究：采用溶液化学计算方法对铝、钒、钼体系进行了计算，从理论上分析了铝钒钼在酸性和碱性溶液中的存在状态和溶解性能，绘制了不同浓度及pH条件下铝、钒、钼水体系的优势组分图，分析了离子浓度和pH值对体系中各离子分布的影响，为水溶液中铝、钒、钼的分离技术的选择提供了基础。

Finally, the writer combined the paper with the request of our country"s current education development to the new period teaching material reforms, concern with the future of our country"s teaching material reforms of chemistry, put forward several suggestions about our country"s teaching material reforms of chemistry: The spirit of teaching material should return to human; teaching material target should more characterful, socializing and more popular; the developing in the flexibility of the teaching material contents ; teaching and learning method"s type in the book should be investigable, cooperant and interactional; teaching material"s diversification"s and modernizations trend etc.

最后，笔者结合目前我国教育发展对新时期教材改革的要求，关注于我国基础教育中的化学教材改革的未来，提出了对我国高中化学教材改革方向的几点展望：教材编制指导思想的&人本化&发展；教材教学目标中的素质化、社会化、大众化的转变；教材内容的弹性化发展；教材的教法、学法的探究式、合作式、互动式转变；教材载体的多元化、现代化趋势等等。

The chemistry behavior research of wollastonite indicated that the silicon-potassium fertilizer has a chemical active in organic acid.The factors affecting manurial effect of silicon-potassium fertilizer are not only soil pH and desilicification,but also content and type of organ in the soil.Wollastonite chemistry behavior indicates that silicic acid can be dissolved out from silicon-potassium fertilizer in chlorhydric acid solution if pH of solution is not smaller than 2. The drop of apparent density,increase of DBP sorptive rate and specific surface for leavings indicate that hydrated silicon oxide is polyporous,and those mineralogic feature presignify that silicon-potassium fertilizer has a role of conservation of both Moisture and Fertility and improving soil structure.After active ingredient releasing,silicon-potassium fertilizer leaves half the substance (non-active ingredient)in soil.

熟料单矿物在酸溶液中的化学行为研究表明，硅钾肥矿物在有机弱酸中的化学活性较好，影响硅钾肥肥效发挥的因素是土壤pH值和土壤的去硅化程度，还有土壤有机质的含量与种类；硅灰石在盐酸溶液中化学行为表明，在反应体系pH不小于2的情况下，硅钾肥矿物大量溶出硅酸根组分；溶解残余物表观密度降低、DBP吸着率和比表面积增加表明水合二氧化硅是以多孔形式存在，为硅钾肥具有保水保肥、改良土壤结构的提供了矿物学依据。

Glass-powder early applied for chemistry industry in prosperous T dynasty, it only applied for ceramic weapon according to history record, it apply for chemistry industry widely applause due to raw material acter diligency limpidity, no heavy metal, chemic physical feature stabilization in modern times.

玻璃微粉最早应用于工业领域的是在盛唐时期，据史料记载，起初只限于陶瓷工艺品的应用和兵器制造。由于玻璃微粉原材料质地坚韧透明、不含重金属、化学物理性能稳定等特点，在现代化学工业中得以了广泛的应用和好评。
