数字特技打造电影视觉盛宴

电影是高科技和文学艺术相结合的结晶.在电影流光溢彩的100多年历史长河中,特技始终如影随形.但电影特技早期作为一种辅助手法,只不过起到了“缝缝补补的针”的作用;而最近的30余年中,由于数字特技的长驱直入,直接改写了传统的电影语言,改变了传统的电影制作手段,并且对电影的本性、创作观和观影观都产生了强烈的冲击.     

越南侬族灵魂观念与取名制度研究

越南峒娄侬族的生活中有三种姓名。第一种是在婴儿时期获得的名字,取名时较为随意;第二种是在进入儿童期后获得的名字,必须遵循家族的字牌;第三种是在成年结婚时获得的名字,夫妇采用相同的名字。三种不同的名字也有着不同的禁忌与限制。第一种和第二种名字在日常生活中被普遍地使用,而第三种名字则是在家族祭祀时或者个体死亡后面对祖先时使用。三种不同名字的制度安排体现了越南峒娄侬族的灵魂观念、历史记忆与自我建构。在对取名制度的传承和创造的过程中,峒娄侬族实现了地方社会的再生产。     

Comparison of Structures and Properties between Wool and Ramie Fibers Treated by Atmospheric Pressure Ar and Ar/O2 Plasma

The technique of atmospheric pressure plasma is of value in textile industry. In this paper, argon (Ar) and argon/oxygen (Ar/O2) atmospheric pressure plasma were used to treat wool and ramie fibers. The structures and properties of treated fibers were investigated by means of SEM, XPS, single fiber tensile tester and so on.The results proved that the effects of plasma treatments depended on structural characteristics of fibers to a great extent, besides conditions of plasma treatment. By atmospheric pressure plasma treatment, wool fiber had significant changes in morphology structure, surface chemical component, mechanic properties and dyeability, while ramie fiber just showed a little change. In additional, Ar/Q2 plasma showed more effective action than argon. And at the beginning of treatment, plasma brought about remarkable effects, which did not increase with prolonging of treat time.
