The research in this dissertation has found a new approach for the ESP study, especially for the research on the precipitability of fly ashes. The results of the research not only give a guidelines for the study and design of fly ash ESP, but also have important theoretical and practical significance in the evaluation of the measurments of fly ash resistivity and particle size distribution and in the research on ESP electrode contigurations and geometries and flue gas conditions.

It was found that the geometries of the studied materials were significantly affected by the ring size and intramolecular charge transfer. The HOMO level, LUMO level, and band gap of the studied model compounds were well controlled by the acceptor strength. However, the electronic properties of the studied polymer showed a significant different trend with the acceptor strength due to the geometrical transformation. The model compound of EDOT-TP and T-TP has the aromatic geometry but is transformed to the quinoid geometry for large intramolecular charge transfer. The small bond length alternation and large acceptor strength in the EDOT-BDP polymer also results in the smallest Eg of 0.7 eV among the studied polymers.

我们发现环的大小以及分子内电荷转移对结构有很大的影响，而小分子的HOMO、LUMO和能隙受到电子受体强度所控制，然而，高分子的电子特性与其构成分子却有明显不同的趋势，这主要是由於分子结构的转变，如小分子EDOT-TP以及T-TP因分子内电荷转移，使其高分子结构由aromatic转变成quinoid；而EDOT-BPP因其键长改变量小和良好的电子受体强度，使其能隙仅0.7个电子伏特。

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。
