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。

The main results were summarized as follows: 1 With the increase of cooling rate, full recrystallization during cooling became difficult to take place and the decrease in dislocation density became slow so that dislocation density in austenite remains higher before phase transformation occurred. 2 Compared with undeformed samples, the CCT diagram under deform conditions has a similar shape, but its position shifts leftwards.

In this paper, thermogram was used to do human face recognition. The thermogram of human face was captured from infrared camera. Image processing technologies were used to preprocess the captured thermogram. Then several features were extracted from the processed thermogram. These features included the distribution of temperature statistics, the perimeter of the face, the length/width ratio of the smallest rectangle which contained the face, and the triangle formed from the three lowest temperature points of the two cheeks and the chin. A three-layer back-propagation neural network was used as the recognition tool.
