摘要：现实世界的事物常常以它的色彩首先进入人们的视觉,唤起人们的美感。高明的作家往往在自己的作品里精心点染描绘色彩,以增强作品的艺术魅力。鲁迅先生在他的小说和散文中就常常运用色彩词勾勒出具有艺术表现力和独创性的各种色彩画面,其艺术功能主要体现在塑造人物、描绘景物、渲染气氛、抒发感情等方面,其深沉冷峻的色调是特定时代的反映。

摘要：针对基于三重球模型的混凝土组成设计方法存在参数计算复杂,在实际工程中使用不便,对其中抗压强度模型和浆体/骨料模型的计算简化处理,提出了一种基于可压缩堆聚模型(CPM)模型的路用混凝土组成设计方法,通过设计实例表明:该方法简单实用,级配优化合理,水泥用量少,混凝土各项指标能够满足设计要求。

摘要：文章以评论当代文学家、国画家梁斌的绘画成就为主线,围绕着他一系列独具特色的作品进行了解读和分析,特别是对他作品中所彰显的精神与品格,对他在绘画艺术上所形成的鲜明风格,均给予了充分地关注和肯定。

摘要：新疆地缘辽阔,民族众多,是一个多民族聚集、多种宗教并存、多种文化融合的地方。受多元文化的影响,新疆的伊斯兰文化既有伊斯兰文化特点的共性,又融入了新疆其他不同民族的优秀文化元素,由此显示出新疆多元文化特有的地域印记和特色。在新疆少数民族的服饰文化现象中,既反映出伊斯兰文化印记的显性特征,又反映出了各自民族文化传承中的个性因素。塔吉克族服饰艺术就是一个非常典型的特色文化现象。

摘要：A new type of sample cell specially designed for micro-Raman spectra study on volatile melts is described. The cell is made of quartz. The lower section of the cell is circular ring-shaped and the one-end-closed hole in the cell is used for locating the heating body. The tube attached to the cell lid for placing the thermal couple is inserted into the sample, which ensures that the temperature measurement accuracy is good. The cell can be sealed for reducing the effect of the composition change caused by the in_homogeneous volatilization. During the Raman spectra scanning, the laser beam is transmitted into the cell through the side but not the top. Meanwhile, a furnace has been designed to match the cell. The heating body is closely coupled with the sample cell, and there is a hole on the side wall of the furnace for the entrance of the microlens. The assembly has performed well in the tested Raman spectrum measurement of molten NaNO3 at 602 ℃.

摘要：研制了一种六维宏微位移可控精密工作台。设计中采用粗精分离的原则,有利于提高工作台的精度,并减小了研制难度。宏位移使用精密燕尾导轨结构。微定位系统使用了压电陶瓷驱动器、柔性铰链和计算机控制,使系统具有极高精度的补偿定位能力。该工作台可在 100mm 范围内运动,平移分辨力为 0.05μm,转动分辨力为 0.3″。

摘要：最近几年,随着全球气候变化,全球温度升高的趋势越来越明显,特别是今年夏天美国高温天气造成多地火灾,阿联酋甚至出现70多摄氏度的极端高温天气,我国部分地区超出正常气温的天气也常有发生.因此,开发极端炎热天气环境中的绿色低碳的降温技术,对于解决气候变化所面临的各种问题,具有越来越重要的意义.个人热管理(personal thermal management)对人体周围微环境的高效调控能力,可以帮助人类应对全球变暖背景下的户外极端气候条件.

摘要：目的探讨儿童产品的可成长性,以提高儿童产品的使用周期,从而满足儿童生理及心理不断成长的使用需求和社会可持续性发展的需要,力求做到既能减少总体消费成本,又能节约社会资源。方法基于可成长性设计理念和可持续性设计方法进行儿童产品设计。结论从儿童产品尺度的可调节性、结构的可拆卸与可组合性、功能的可转换与可拓展性、互动体验的趣味性及益智性等4个方面进行阐述,最后以一款"儿童木马玩具"产品为例,运用可成长性设计方法对其进行创新设计,并进行论证。
