The evolution process under the control of the multigeodynamic force system (including the boundary forces of Eurasia-Pacific-Indian three massive plates around Nansha block, effects of the deep mantle, relative soft layer-sliding planes within Nansha lithosphere block and the earth's rotational inertial force) can be briefly divided four stages: the late Cretaceous to the early Eocene stage of uprilfing-erosion and shear-extension caused by the oceanwards-eastwards withdrew of Pacific subduction zone and the delamination of proto-subducted slab after the stage of pre-Cretaceous pre-rifting active continentoceanic plate margin. In this stage, the Nansha transcrustal layering-block started to move southeastwards on the Nansha transcrustal layer-sliding plane, meanwhile, the Andu-Bisheng and Liyue-Banyue basement layering-block slid on their upper-crust layer-sliding planes, and Xibu accretion zone was formed. Successively, it entered the stage of the mid-Eocene to early Oligocene, when NW-SE sea-floor spreading occurred in the southwest subbasin owing to the slip-line field initiated by the collision between the Indian and Eurasian plates, Zengmu foreland-basin started to develop in the same time. And in the stage of late Oligocene to early Miocene, near NS simple-shear extension and sea-floor spreading in the central subbasin of eastern South China Sea resulted from the south-southeastwards drawing-force of the mantle-flow. The crustal layering-blocks and the Miri accretion zone formed also in this stage.

The results show that the introducing of multivinyl monomer and CaCO3 can slow down polymerization rate to different extent.Using 1％～5％ trimethylolpropane trimetbacrylateor divinyl benzene,tight encapsulation of CaCO3 can be realized and beyond 94％PS cannot be extracted. The amount of crosslinker or emulsifier should be accommodated when the load amount of CaCO3 is increased.CaCO3 content in the product increases consequently with the increase of the loaded amount of CaCO3,which can be known from FT-IR and TGA.TEM observations reveal that when the load amount of CaCO3 is 14.8％,most CaCO3 particles are encapsulated and each latex particle contains one CaCO3 particle.Composite particles have well-defined core—shell structure and the thickness of polymer shells is around 10 nm.However,the thickness of polymer shell decreases and many free CaCO3 particles appear when the load amount of CaCO3 reaches 29.3％and 58.7％,respectively.

结果表明，多乙烯基单体以及碳酸钙的引入会使聚合反应速率有不同程度的降低；使用1%～5%的TMPTMA或DVB，可实现PS对碳酸钙颗粒的牢固包覆，不可抽提的PS达94%以上；当碳酸钙用量改变时，需要适当调整乳化剂和多乙烯基单体的用量；IR和TGA的结果表明，随着碳酸钙用量增加，产物中的碳酸钙含量也相应增加；TEM照片和计算结果显示，当碳酸钙用量为14.8%时，绝大部分碳酸钙颗粒被包覆，且基本上每个乳胶粒中包覆一个碳酸钙颗粒，复合粒子具有清晰的核壳结构，壳层厚度约为10 nm，而当碳酸钙用量增加到29.3%和58.7%时，壳层厚度减小，并且出现较多裸露的碳酸钙颗粒。

Based on the previous experiments, we choose CNTs/CdS core-shell nanowires as inorganic materials and poly(benzyl-ether) dendrons with thiol functionalities as organic solubilizer. The solubility of CNTs/CdS core-shell nanowires in normal solvents was expected to improve through chemical interactions between core-shell nanowires and solubilizer. The enhanced solubility can improve facility in processability. It also provides a new application method in nanomaterials.
