Examples
- The existence of pzt has bi - directional effects on the conductive circuit of vgcf , which leads to an evident semi - conducitve plateau area in the electrical conductive curve
由于pzt的存在对vgcf导电网络的形成具有双重的作用，这反映到电导率随vgcf体积分数的变化曲线上，则是在半导区存在一个明显的半导区平台。 - In this section , conclusions are made as follows : ( 1 ) with the increase of vgcf content , the cpe / pzt / vgcf composite represents insulator , semiconductor and conductor
通过对cpe / pzt / vgcf复合材料的导电性能和粘弹性能的研究发现： ( 1 )随着vgcf体积分数的增加， cpe / pzt / vgcf复合材料呈现由绝缘材料到半导体、导体材料的导电特性。 - When vgcf volume content is low in cpe / pzt / vgcf composite , the existence of pzt can improve the vgcf distribution in cpe matrix , but the existence of pzt blocks the networks of vgcf when vgcf content is high
( 2 )通过对cpe / pzt / vgcf复合材料动态机械性能的测试结果表明， vgcf的体积分数当处于半导区时具有更为显著的压电导电减振作用效果。 - ( 2 ) the damping mechanism of multi - energy transitions takes effect when the vgcf content is among the semi - conductive area . when the vgcf content is low ( below 8 % ) , the vgcf conductive circuit does not form and the heat loss is quite little . when the vgcf content is higher than 20 % , the transition efficiency between electric energy and heat is limited
这是由于当vgcf含量太少时(低于8 ) ，复合材料中导电网络还没有来得及形成，起不到能量损耗的目的；而当vgcf含量太高时(高于20 ) ，电导率太高，复合材料成为电的良导体，电能与热能之间的转换效率很低，能量损耗也不高。 - ( 4 ) only when the resistance r = l / c , the transition efficiency between electric energy and heat reach its maximum value , which makes it possible to design the high performance damping composites of multi - energy transitions by adjusting the vgcf content . cpe / zkf / vgcf composites : in the cpe / pzt / vgcf composites , the conversion efficiency from force to electricity is very low because of the obvious difference of rigidity between cpe and pzt , which leads to the damping effect of multi - energy transitions is not so evident as the viscoelasticity of the matrix cpe , especially during the cpe glass transition
Cpe / zkf那gcf复合材料:针对cpe / pzt / vgcf复合材料中由于cpe和pzt之间模量差异较大，导致cpe和pzt之间的应力传递欠佳，影响力一电变换效率，从而压电导电减振作用效果并不十分显著的现象;本章中采用极性有机小分子双( 2一轻基- 3一环己基一5一甲基)一苯基]甲烷( zkf ) ，而不采用pzt ，消除了pzt与cpe模量方面差异的影响。
