The content of 2-EHA was varied from 80 % to 40 %. The adhesion was estimated by measuring tensile strength and work-to-break of impregnated roving. The film behaviors were evaluated in terms of breaking strength, breaking elongation, work-to-break, and flex- fatigue resistance. It was observed that the viscosity, adhesion, and film behaviors of the copolymers strongly depended on the content of 2-EHA. Excessively increasing or decreasing the content of 2-EHA units incorporated into the copolymeric chains reduces the serviceability of P（2-EHA-co-AA） in warp sizing. The adhesion and film behaviors of the copolymcr reach their maximal values at mole content of 50 % simultaneously. Therefore, the copolymer used as sizing agent should be synthesized under equal mole of 2-EHA and AA in monomer formulation.展开更多

However, ascribed to the differences between Chinese and English cultures, plant of the same kind exhibits similar, distinct or vacant characteristics. This paper adopts comparison method so as to compare and to analyze the differences and similarities of cultural connotation contained in plant emerging in Treasure Island （a representative of western adventure literature） and The Swordsman （a representative of Chinese martial arts literature） and roles plant plays in a certain chapter, or the whole story. The literature study presents a general knowledge of research theories in this field and cultural background. Moreover, the induction method integrates and summarizes the prior analyses and researches. Reasons underlying those cultural differences are also expounded, including legend and folklore, literature works and convention and custom. The conclusion is that analyzing the cultural connotation of plant is of significance for understanding the corresponding cultural differences as well as appreciating adventure and martial arts literature.展开更多

Instances are cited with the use of imagery respectively in character portraits, dialogues, and scenes. It proves that an integrated use of this rhetorical device is an important means for vivid and impressive accounts in literary works, for it helps to build up the context for characterization, presenting the characters alive and distinctive, and effectively reveal the theme of the novel, bringing about authentic feelings to readers.展开更多
