谁能帮帮我啊？？我会报答大家的。急。非常急。谢谢！

Inorganic / shell polymer materials because both inorganic and polymer merits of particular concern. These excellent properties of core-shell material is conveyed in the light, electricity, magnetism, and the catalytic machinery displayed a wide range of applications. Preparation of inorganic / polymer shell material many ways, emulsion which is one of the most simple and easy preparation of monodisperse nano-inorganic / polymer particles method. In this second, three chapters, the main silica particles to study nuclear, poly styrene sulfonate to shell silica / poly styrene sulfonate-coated microsphere synthesis, and discussed the catalyst, different solvents on silica microspheres, particle size and morphology of the initiator and monomer, Silica particles and the reaction medium ratio on silica / poly styrene sulfonate-coated microspheres impact. And the use of FTIR and SEM method to detect nanoparticles and polymers were characterized and research. Keywords : composite microspheres, shell, precipitation polymerization

cpm是关键路径法Critical Path Method的简称，是基于数学计算项目的计划管理方法，是网络计划图方法的一种，关键路径法将项目分解成为多个独立的活动并确定每个活动的工期，然后用逻辑关系（结束-开始、结束-结束、开始-开始和开始结束）将活动连接，从而能够计算项目的工期、各个活动时间特点（最早最晚时间、时差）等。在关键路径法的活动上加载资源后，还能够对项目的资源需求和分配进行分析。
