The results show that the compound conductive fiber has typical structure of sheath-core consists of black greened polyaniline electric conductive deposition as the skin and the white polypropylene matrix fiber as the core, which makes the compound fiber preferable physical mechanical property. The intensity and the elongation ratio of the electric conductive fiber are decreased but the thermal stability is enhanced after modified. The compound fiber has the good acid resistance but poor base resistance. The thermal stability of the compound fiber prepared by 4-methyl-benzene sulfonic acid is better than that prepared by hydrochloride acid. Moreover, the compound fiber can be re-doped by other organic or inorganic acid after freed from the adsorbed acid. Furthermore, the electric conductivity of the compound fiber decreases with the temperature increasing but hardly changed with the humidity. The adsorptive ability and therefore the content of the polyaniline, the constant of electric conduction, and the durability of the compound fiber can be enhanced by thinning the diameter, section heteromorphosis, section heteromorphosis and plasma treatment of the surface or blending with COPET of the fiber.
结果表明:复合纤维是聚丙烯与聚苯胺的共混体系,具有典型的皮芯型结构,皮层为墨绿色的聚苯胺沉积层,形成连续的导电通道,芯层为白色的聚丙烯基质纤维,提供物理机械性能;导电改性后纤维的强度、强力和伸长率均有下降,但热稳定性得到提高;复合纤维的耐酸性比耐碱性好,以对甲苯磺酸做掺杂酸比盐酸掺杂聚苯胺热稳定性好,脱掺杂后的复合纤维,可用其它无机酸或有机酸进行再掺杂;复合导电纤维的电导率随温度升高降低幅度较大,但几乎不受湿度影响;基质纤维细旦化、截面异形化、表面等离子体处理或共混COPET等改性处理均能提高纤维的吸附性,进而提高复合纤维表面聚苯胺含量、电导率和耐久性。

With the observation of the outward appearances, it can be known roughly that if the sample was added with adulterations. Since the beeswax dissolves in the benzene but the adulterations, such as gypsum, starch and so on do not, these can be determined. By the verification of acid value and alcohol dissolve ability, the acid or non acid added can be determined. By the change of saponification value, the ester or non ester added can be determined. By the carbonification degree in the concentrated sulphuric acid, the mineral wax, such as paraffin wax added can be determined.
通过样品外观的观察初步定性是否掺有杂质;利用纯蜂蜡在苯中溶解,而掺入的石膏、面粉和淀粉等杂质在苯中不溶而定量鉴定这类杂质;由酸值变化和乙醇溶解物的量,测定掺入的硬脂酸等酸性物质或其它的非酸性物质;由皂化值变化,定量测定掺入的动物脂等酯类物质或其它的非酯类物质;根据蜂蜡中的烃类在浓硫酸中可被炭化,加入的石蜡等矿物蜡不被炭化来测定此类掺杂物。

A-Methylnaphthalene contains a methyl group, which is a strong donor group, so the reaction of a-methylnaphthalene with C14 AOS acid had a higher conversion of aromatic than did the reaction of benzene with C14 AOS acid. After alkylaryl sulfonic acid is formed, it will continue to react with another AOS acid to rapidly produce dialkylaryl disulfonic acids owing to the electron- donating effect of the long alkyl chain in the alkylaryl sulfonic acid molecule.
a-Methylnaphthalene包含一个甲基集团,这是一个强大的捐赠团体,所以 a-methylnaphthalene反应出了与C14酸更高的转换的反应比苯与C14活性氧酸。alkylaryl磺酸为后形成,它将继续与另一出酸 dialkylaryl disulfonic迅速产生的电子-酸捐赠的长期效果在alkylaryl烃链磺酸分子。

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。
