Characteristics of Coaxial Dielectric Barrier Discharge at an Atmospheric Pressure with a Swirling Gas Argon/Oxygen Mixture for the Surface Modification of Polyester Fiber Cord

A newly developed coaxial dielectric barrier discharge reactor with a length of 1000 mm at an atmospheric pressure was used for plasma treatment of polyester fiber cord in a roll-to-roll manner. In this reactor, swirling mixture gases of oxygen of about 1% and argon with a flow rate of 1.5 to 2.7 L/min ensured the gas usage sparing, discharge uniformity and efficient fiber surface modification. The water contact angle and surface morphology of the treated fiber were measured. The results show that the surface oxygenation is mainly responsible for the wettability improvement of the fiber cord when passing through the plasma zone at a linear speed of 3 to 8 m/min. The specimens of modified-polyester fiber reinforced rubber composite were also prepared for the interfacial shear strength tests. Furthermore, the effect of adding oxygen into argon discharge on the fiber surface oxidation was correlated with optical emission spectroscopy. Finally, the effect of adding oxygen into argon discharge on the kinetic processes of the active species generation were also analyzed.

论形象在艺术设计中的地位和作用

在社会生活中事物的形象与内容是相辅相成、辩证统一存在的两个方面。首先,本文从实用性和审美性两个方面入手强调了商品的形象的重要性,说明了在商品设计中不能只注重事物的内容同时也要注重商品的形象。接着分析了形象与内容是不可分割的两个方面,提出了这两者相互相成中所包括的内涵,即文化、时代、以及在现代新观念中的定位。最后本文揭示出现在现代艺术设计中真、善、美的统一应该是追求的最高目标。
