It was investigated that of mass rate of momomer （mor/mAN）, polymeration temperature and time, and feeding ratio of BLAF effect on the structures, morphology, conductivity, magnetic property of composites by the orthogonal optimum design. The results indicated that poly （OT-co-AN） copolymer had a better coating on BLAF particles, and there were some interactions between components in the composites. The magnetic properties of the composites were related to content of the magnetic BLAF particles in it. The feeding ratio of BLAF had a significant influence on constitute and conductivity of the composites, followed by the temperature. The reflection loss and the effective bandwidth of composites for electromagnetic wave were at- tributed to the synergistic effect between poly（OT-co-AN） and BLAF. The poly（OT-co-AN）/BLAF composites with mass ratio of BLAF to mix monomer （moT^mAN =1：1） equal to 5/1 at 10 h in 25~C had a maximum synergistic effect between its compo- nents, showed a maximum reflection loss of -26.94 dB at 14.10 GHz and an available bandwidth of 8.54 GHz. It was sug- gested that the composites can be used as a advancing absorption and shielding materials for electromagnetic wave due to their favorable microwave absorption properties.展开更多

These may be summarized as a ＂common existence＂ centering on the values of ecological commonality and ecological justice; ＂common action＂ and ＂common enjoyment＂ based on the commonality of justice and the promotion of dialogue; and ＂co-presence＂ based on rational inter-subject communication.展开更多
