摘要：针对随机优化算法计算量大和最优响应面法容易陷入局部最优的缺点,采用EI最优策略综合平衡响应预测值及预测精度,建立了高效的优化系统.使用该方法进行了翼型气动外形优化设计,结果表明该方法将翼型阻力系数降低22%,具有良好的优化精度,而总计算耗时与粒子群算法相比约降低68%,说明了该方法的可行性和有效性.

摘要：Contemporary Chinese aesthetics have three important ＂traces＂： ego aesthetics represented by Chinese fantasy literature; convoluted aesthetics represented by the contemporary Chinese movie ＂Loss＂ and the novel Monk; and the fetish aesthetics of symbolic exchange, as represented by Huang Xiaoming＇s wedding and the auctioning of Jack Ma＇s painting. These represent the transmutation of contemporary Chinese aesthetics from adolescent ego aesthetics to adult convoluted aesthetics to the fetish aesthetics of symbolic exchange, thus completing the successive change of logic from ego to society to reality. In tracing these successive changes in logic, we are thinking about questions raised by the times. These concern the future of Chinese contemporary aesthetics and constitute an aesthetic revolution. They mean that contemporary Chinese aesthetic practice has moved from text to community and then evolved into social reality. Further, they also smack of mutual imitation between aesthetics and life. Contemporary Chinese theorists should be actively involved in the revolution, responding to major issues and, as they face social practices, acquiring transcendental characteristics in contemporary aesthetic leadership.

摘要：自弗洛伊德创建精神分析理论以来,精神分析运动已历百年,其内部有关"自我"的研究一直在不断深化,阿德勒的个体心理学、荣格的分析心理学,以及之后的自我心理学、社会文化学派都从不同角度、不同层面对"自我"进行了挖掘和探索,使"自我"的概念得以不断丰富和完善。文章对精神分析理论中"自我"(self与ego)概念进行了梳理,以厘清精神分析运动百年的发展脉络,进而加深对"自我"概念的理解。
