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.

With reference to the experience of specific practice on strategic alliance in typical domestic and overseas port like New Jersey Port in New York, port of Kaohsiung, Keelung and Taizhong, major ports in Yangtze River Delta, the possible modes of Rizhao Port strategic alliance were proposed. Based on the previous analysis, specific design on the supply chain management system of Rizhao Port viewing from strategic alliance was given in this dissertation, which mainly covered two aspects. On the one hand, based on the overall review of common design process, structure design and selection of partnership of supply chain management, and with consideration of the development trend of Rizhao Port, the double-sector style supply chain structure mode of Rizhao Port was put forward based on strategic alliance. On the other hand, in order to make it more clear on the specific process and contents of this kind of supply chain structure, the specific implementation of five supply chain for Rizhao Port in which capital was taken as the hub were proposed, named as, the coal supply chain based on norm regular ship transport mode, the ironstone supply chain based on cost optimization, the crude oil transport supply chain with the aim of extending petrifaction industrial chain, the timber transport supply chain based on circulating economy concept, and the farming transport supply chain based on futures theory.
