The results show that the polymer determines the electricity conducting of coal filled polymer composites. The coal filled PP composites is an insulating material, and be independent of coal type, its direct current resistivity is above 10〓Ω·cm. The resistivity drops with the content of coal when using anthracite, but it is also above 10〓Ω·cm, and the surface modification of coal, especially alkylated, resumes the insulance of composites.

X射线衍射测试表明即使在高变质程度下煤中的石墨晶区含量仍较低，煤填充聚合物复合材料电性能主要由基体材料性能决定，通过动电容静电计对煤填充聚丙烯复合材料直流电导性研究表明，煤填充聚丙烯复合材料是绝缘材料，其绝缘电阻在10〓Ω·cm以上，在高含量情况下，仍能保持良好的绝缘性，而与煤种无关。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
