粘土

There exists a characteristic stiff clay of Epipleistocene late period in the stratum,which indicates that the local area is not the growth place of the ancient river valley during the postglacial period.

孔深39～41m存在的晚更新世晚期特征硬粘土标志层，指示本地不是冰后期古河谷的发育地。

Previous studies indicate two possibilities of the formation of the greigite: 1 the seepage of seawater during the postglacial transgression provides sulfate and makes the reducing diagenetic conditions; 2 it may be precipitated as the authengenic mineral in marine or lacustrine sediments during the low sea-level stand of the Late Pleistocene.

本研究在前期工作基础上，针对已发现的硫复铁矿富集区选择典型柱状样6根(深约1.5-2.5m，长柱样；B436、B437、B439、B459、B483、B484)，同时于扬子浅滩前缘新获取柱状样4根(深约0.3-0.5m，短柱样；ST9、ST13、ST15、ST23)，进行了U系测年，粒度分析、磁性测量、X—射线衍射分析、微体古生物鉴定分析、粘土矿物和化学元素含量测试，试图揭示东海外陆架浅部地层结构、揭露硫复铁矿在地层中的分布规律及成因机制，从而探讨该区晚更新世以来海平面波动模式及其控制下的地层发育。

The research of polymer/layered silicate nanocomposite was introduced detailedly, including the classify, property and the latest research advance. On the basis of consulting the document and the exploratory experiment, the experimental method which first creative preparing poly (acrylonitrile-vinyl acetate)/raontmorillonite nanocomposite by emulsion intercalation copolymerization was established; the structure and property of polyacrylonitrle different molecule weight with inorganic mineral super fine nanocomposite was reseached. The reaction principle of PMMA by photo-initution was explored. The mixture principle with productor condition, property of PE/Clay nanocomposite milt insert was seal prived. By PS/Clay nanocomposite munufacture, the monomer ins-polymerization and polymerial solution was proved.

在查阅文献和探索性实验的基础上，确定采用乳液原位插层聚合方法首先创制了聚/蒙脱土纳米复合材料，利用正交实验得出了最佳实验条件，通过X射线衍射和红外光谱对纳米复合材料的结构进行表征，研究了复合材料的溶解性能，并测定了其溶液的绝对粘度；研究了不同相对分子质量的聚丙烯腈与不同的无机矿物超细粉复合材料的结构与性能；探讨了在蒙脱土中光引发聚甲基丙烯酸甲酯的反应机理；通过聚乙烯与粘土的纳米复合材料制备，探讨了热塑性树脂熔融插层复合机理与最佳工艺条件和复合材料性能关系；通过聚苯乙烯与蒙脱土纳米复合材料制备，验证了单体原位聚合插层和聚合物溶液插层机理。

Clay prepared in this way is as well mixed as by a pugmill.

粘土准备以这种方式混合，以及作为一个

Before the invention of the pugmill, craftsmen would wedge a large mass of clay with their feet into a circular mound.

前发明的pugmill ，工匠将楔形广大粘土与脚成一个圆丘。

A cut of sheep's hair touched with the genius of man becomes rament for a king .If it is possible for leaves and clay and wood and hair to have their value multiplied a hundred , yea a thousandfold by man ,cannot I do the same with the clay with bears my name ?

柏树。羊毛经过人的创造，可以成百上千倍地提高自身的价值，那么我们为什么不能使自己身价百倍呢（注：作者意思是我们均为上帝用粘土所造）？

The results indicated that with this new adsorbent the efficiency of decolourisation was 85.3％and the productivity of sebacic acid was 92.0％ under the condition of 2％ of adsorbent amount used with 30min of reaction time at 90℃.
