微胶粒

TEM observation indicates that there is micro-phase dispersed in EPDM/ZDMA vulcanizate. The size of the fine particles is about 10 to 40 nm and the size slightly increased with increasing ZDMA content.

TEM观察表明，EPDM/ZDMA硫化胶中均匀分布着微分散相，当ZDMA用量从10份至80份变化时，这些微分散相的粒径也越来越大，总体上在10～40nm之间。

Much coagulation coul d be found to be adhered to the wall of reaction vessel and mixer when this cros slinker was used for conventional emulsion polymerization whereas coagulation co uld be greatly reduced and no obvious bulking of particle size of the product wo uld occur when this crosslinker was used for microemulsion polymerization and do sage and proportion of emulsifier wer.

将此交联剂用于乳液聚合中，若采用常规乳液聚合方法，反应器壁及搅拌上会粘附有大量凝胶；采用微乳聚合的方法并调整乳化剂用量及比例，可大大减少凝胶量，同时使产品粒径无明显粗大化现象。

In this dissertation, based on glass microspheres and submicron silicon dioxide, the silver-coated core-shell shielding particles were prepared by liquid phase chemical deposition and layer by layer packing technology. The influences of the preparation conditions on the structure of the synthesized core-shell particles were also systemically studied. The conclusions are enumerated as follow:(1) Monodispersed submicron silicon dioxide spheres in the size range of 250～550 nm are synthesized by Sol-Gel method using ammonia as catalyst.

本文在前人研究的基础上设计出以微米级玻璃微珠为基核，采用液相化学沉积法和层层包裹法制备表面包银的核壳粒子电磁屏蔽剂，并对液相化学沉积法和层层包裹法的制备工艺进行了系统研究，取得了以下主要结论：(1)以氨水作催化剂，采用溶胶－凝胶法制备了粒径分布在250～550 nm之间的二氧化硅微球。

Study shows that compaction and cementation can play a destructive role in Suining formation reservoir,while dissolution and fracturing can play a constructive role in that.The main facies of Suining formation are ferruginous-shale film,anhydrite,dolomite and calcite.The micro-fracture and grain-edged fracture mainly resulted from compaction fracturing,compaction slipping and tectonic dynamic force greatly improve the reservoir permeability.

研究表明：①对遂宁组储层起破坏作用的是压实作用、胶结作用和交代作用，而溶蚀作用、压裂作用则对储层起到建设性作用；②遂宁组最主要的成岩相组合为铁泥膜－硬石膏－白云石－方解石成岩相；③由压实破裂、压实滑动和构造动力形成的微裂缝、粒缘缝有效改善了储层的渗透性。

The experimental results match the theoretical calculation well. The formula of theoretical calculation can be widely applied to study the effect of physicochemical properties of alginate and parameters of electrostatic droplet generator on diameter of gel microspheres of calcium alginate.

采用静电液滴发生器制备海藻酸钙凝胶微球，研究了液滴形成机理、微球形态和粒径变化，并通过理论推导得到了微球粒径的计算公式，其计算公式能够很好的吻合实验结果，具有普遍的适用意义。
