As a result, the author discusses the thermodynamics habitus for the minerals either. With the calculation of the thermodynamics modeling, we run the dissolutionmodeling experiments for primary minerals (potash feldspar, albite, anorthite, andpyroxene, hornblende), which is under the conditions of organic acidic and 20 varietytemperature and pressure. The dissolution modeling experiments include 4 anorthitedissolution experiments, 8 pyroxene dissolution experiments, 8 hornblendedissolution experiments. We catch the records on the X ray diffraction, chemistryanalysis, SEMphotos, and the PH parameters. By theway, we discuss the dissolution habitus for the minerals either.

Each starch reagent has its own mode of action on mineral surface, such as primary starch mainly by hydrogen bond, cationic starch by the co-action of hydrogen bond and electrostatic force (for minerals with negative charge on its surface), while carboxymethyl starch, hydroxamic acid starch and dialdehyde starch principally by chemical force accompanied with hydrogen bond and electrostatic force in part. Such chemical forces ensure the close adsorption of reagent on diaspore surface and enforces the hydrophilic of mineral surface. Also the branched chain enable the starch to cover the collector adsorbed on mineral surface, so as to depress diaspore furthermore.

不同淀粉药剂在矿物表面表现不同作用，原淀粉主要是氢键的作用，阳离子淀粉是氢键和静电力的共同作用，羧甲基淀粉、羟肟酸淀粉和双醛淀粉离子性药剂与矿物间的作用除了氢键、静电力外，更重要的是与矿物表面金属离子间产生的化学作用，使药剂能牢固地吸附在一水硬铝石矿物表面，增加矿物表面的亲水性，同时，淀粉支链结构的存在，使它能够掩盖吸附的捕收剂，达到抑制一水硬铝石的目的。

This paper also shows the distribution of the fluorine in sediments of the area is mainly controlled by the chemical composition of the material from the surrounding islands, and the element seems to be incorporated by the hornblende at the most extent, thus the correlation between the element and the hornblende amount in the sediments can be expressed statistically as following: F=217+lnVh.

研究结果表明，测区沉积物中氟含量分布主要受周围岛屿风化基岩的化学成分制约；沉积物中主要含氟矿物：萤石/磷灰石、黄玉、黑云母等含量极低，氟在沉积物中赋存的矿物相主要与角闪石[AX_2Y_5Z_8O_(22)_2]有关。氟含量与碎屑矿物中角闪石的体积比间的关系式可大致表示为：氟含量=217+361nV_H；间隙水中的低氟主要由测区化学风化不发育及氟的钙盐沉积所致。

晶体化学方法是研究矿物热膨胀系数的有效方法，但由于矿物的热膨胀系数和晶体化学参数之间的定量关系尚未完全弄清，目前仅仅能对简单结构矿物的热膨胀系数进行计算，结构、成分较复杂的矿物的热膨胀系数计算尚缺乏好的晶体化学模型。

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。
