摘要：2006年×月×日上一代的艺术家们,我们中国最伟大最伟大的画家们和作家们,最用心的其实不是艺术,而是政治,是国计民生。鲁迅和郭沫若,闻一多和齐白石,刘海粟和徐悲鸿……这些民族艺术家的话题总是在怎么救中国,怎么振兴中华民族上面。好吧救中国已经不用谈了。中国已经得救了。但是振兴民族恐怕还是不能放弃,就在我们这一代玩命赚钱的时候,玩命哈日的时候,我们正在成为一个拥挤,

摘要：非圆则方,称得上腕表世界的恒久潮流。欣赏圆形腕表的人,可能信奉"圆滑"的处世哲学,方形腕表则让佩戴者隐隐显得棱角分明。但是这个世界不是除了黑暗就只有光明,腕表的造型更可以在或圆或方之间千变万化。以下十数款造型各异的腕表,恰如不同人格与身份的隐喻——"表如其人"这句话我是一直深信不疑的!

摘要：针对一次试验性舞蹈项目,设计开发了交互多媒体系统,根据舞蹈编导对每段舞蹈的不同需求,合作设计了多种交互手段,对舞者的动态进行运动捕捉和视频捕捉,并进行图像分析追踪舞者的动态.然后应用分析结果进行生成艺术创意,通过混沌艺术算法、图像处理方法和粒子系统物理模拟等方法实现舞蹈编导需要的视觉效果.最终通过多屏幕投影呈现给舞台,增强了其艺术效果和交互性.同时还对交互媒体创意过程中的合作和工作流程进行了探讨.

摘要：对高质量水的需求越来越多，如此促进了大直径反渗透和纳滤元件的开发。这些元件具有规模经济的优点，占地面积小，制水成本低。本文将从概念到生产试验考察元件的开发。

摘要：近年来,随着汽车自动驾驶、数字化、电动化技术的不断发展,汽车的功能不断增加,车辆内部线束也随之增加。由于过多的线束导致车辆自重增加的问题日益突出。为了实现能源的高效利用和出行方式的可持续性,开发人员需要通过优化线束布置来尽可能多的减轻车辆自重,同时降低成本。由于与线束相连的车辆零件位置固定,因此需要一个算法在车辆零件位置为限制条件下,优化车辆线束布局。之前的研究方法通常只考虑线束设计的部分限制因素,且没有考虑线束三维结构。在本文研究中,开发了一种新型的优化线束布局的方法,该方法考虑了与包装,温度负载以及装配难易相关的各种限制因素。该方法可以根据设计需求来控制线束布置方法,如在沿着车辆纵轴方向布置更多线束,以避免在车辆外围布置线束。通过该方法,可以高效地计算出线束长度、直径,以及精确的布线路径。

摘要：基于一台三缸1.5TGDI增压直喷发动机研究了三火花塞点火均质稀燃对发动机性能的影响。结果表明:三火花塞可有效拓展稀燃极限,压缩比15时,采用三火花塞在2000 r/min、8 bar BMEP的特征工况点可实现lambda 1.95的稳定燃烧,最低油耗相比单火花塞降低约5 g/(k W·h),NO_(x)原始排放可降低至约50×10^(-6),此时lambda受增压能力限制难以进一步增加;压缩比增加至16所能实现的最低油耗相比压缩比15改善不明显,且稀燃极限有所下降。三火花塞对爆震倾向改善作用较小,但可显著加快稀混合气的燃烧速率,相同lambda条件下其燃烧持续期相比单火花塞可缩短约3-6℃A,lambda 1.95时的燃烧持续期相比当量燃烧仅增加约2℃A。通过对潜在最高热效率的研究表明,采用三火花塞设计可在压缩比15条件下最终实现45.02%的有效热效率。
