The inserting method and properties of the composite materials in consist of omt and poly ( styrene - butyl acrylate ) had been researched ; the ultra - fine organic rigid particles crosslinked polystyrene ( xps ) has been synthesized by emulsion polymerization , the effect of the synthesis process on the size of organic rigid particles was discussed . the cause of the increasing mechanical properties of pp composite materials , which were strengthened and toughened with organic rigid particles and elastomer , had been investigated . the results of studying viscosity and precipitate height of sio2 nano - particles suspension showed that the sio2 nano - particles are very good dispersed by dp270 or cat 639w dispersant 通过粘度法和沉降法测定结果的一致性，说明分散剂dp270和cat639w对sio _ 2纳米粒子有较好的分散性， dp270的最佳用量为0 . 2时悬浮液粘度从35 . 1mpa ? s降为23 . 3mpa ? s ， cat639w最佳用量为0 . 4时悬浮液的粘度从35 . 1mpa ? s降为23 . 1mpa ? s ；通过研究分散剂存在下纳米粒子的苯丙乳液聚合动力学，发现纳米粒子的存在对乳液聚合有一定的缓聚作用，并讨论了乳化体系、温度、引发剂、表面处理剂以及纳米粒子用量对聚合的影响。
With the development of preparation technology , people have begun to realize the importance of metal - metal fuctionally gradient materials ( fgm ) . up to now , the researches about metal - metal fgm by co - sedimentation under low temperature are insufficient , and most of researches are concentrated upon the design or fabrication 目前，针对使用共沉降法，在相对低温下制备的金属/金属梯度功能材料的研究还相对较少，而且当前的研究主要集中在制备技术方面，在微观组织研究方面还存在一些空白领域。
Powders properties of different phases such as the granularity , the shape and the component have been analyzed by the methods of sieving , gravity sedimentation , spectrophotometry , scan electronic microscope ( sem ) , transmission electronic microscope ( tem ) and x - ray diffraction ( xrd ) . the results show that technic of ball milling and parameters of heat treatments are important influencing factors to properties of cu - zn powders 采用筛分法、重力沉降法、分光光度法、扫描电镜法、透射电镜法和x射线衍射法对不同阶段的铜锌粉末的粒度、形貌、成分等性质进行了分析，结果表明：球磨工艺及热处理参数对铜锌粉的性能有重要影响。
