明清设计制度研究导论

设计制度研究是设计学与社会学的交叉研究,是认识设计、认识物质社会结构的一种视角。明清设计制度研究是在这一命题之下进行的历史学研究,主要对明清涉及设计制度研究的学术成果、原典、图谱及相关研究方法进行整理,寻找对明清设计产生影响的政治动因和文化动因,以便深入分析器以藏礼包含的多重信息及其在古代社会的真实表现,梳理古代中国设计制度的传承方式。     

科技发展与生态文明的关系

国情和世情决定中国最迫切的任务仍是发展和改善民生,科技能很好地解决能源、资源供需矛盾,但以破坏生态环境换取的发展是不可持续的,这就要求科技以更生态、更文明的方式与自然相处,帮助人类文明向生态文明发展.以科学思维和人文思维作指导,奠定生态文明建设的理论基础,激发绿色技术的发展,实现技术的生态转向,让生态文明建设从理论走向实践.技术的生态转向首先要将生态环境纳入到技术使用的考量之中,技术完全参与利用和改造自然的循环过程,其次还要专门发展绿色生态技术.     

早期现代主义产品形态变化的驱动因素

概述了早期现代主义产品形态变化的主要特点,对产品形态从物质基础与审美观念两个层面加以观照,并进行详尽地对比分析。通过这一时期产品形态的对比,试图从社会变革、艺术观念、技术与生产以及理念形态与功能实现的结合点等方面,来阐释早期现代主义这一特定时期产品形态变化的驱动因素。

Rapid Prototyping and Manufacturing Technology: Principle,Representative Technics,Applications, and Development Trends

The rapid prototyping and manufacturing technology (RPM), is an integration of many different disciplines. It is based on an advanced dispersed-accumulated forming principle and originated from 1980s. It generates an entity by first forming a series of layers according to the dispersed section information of the digital model, and then piling the formed layers sequentially together. It is capable of forming parts with complicated structures and non-homogeneous materials. Traditional RPM techniques are mainly used as prototypes in product invention process, such as stereolithography, three-dimensional printing, laminated object manufacturing, and fused deposition modeling. Later, with the progress of material and enabling technology, many new RPM techniques emerged out and have been already applied in the fields such as rapid tooling/moulding, direct formed usable part, nano-/micro-RPM, and biomanufacturing. This high flexible digital manufacturing method has a likely ability to become an almighty forming technology.     

东濮凹陷轴向重力流水道沉积研究

利用地质、测井和地震等多种资料进行的综合研究表明,东濮凹陷桥口和新霍地区沙三段中发育轴向重力流水道沉积,它们主要由灰黑色块状泥岩与平行层理砂岩、块状层理砂岩、递变层理砂岩及合卵石砂岩构成,在垂向上组合成鲍玛序列的AE、BE、ACE、BCE和CE等。依据研究区轴向重力流水道沉积特征,将其划分成近源和远源水道、近源和远源水道侧源等4个微相,并描述了这4个微相的沉积特征,建立了沉积模式。油气勘探实践表明,重力流水道砂体是我国东部陆相断陷湖盆中重要的油气勘探新目标,它具有良好的储集物性,并含有丰富的油气。     

高效液相色谱法同时测定树鼩脑组织中的去甲肾上腺素,多巴胺,5-羟色胺及色氨酸

应用高效液相色谱(HPLC)--荧光检测,在一根带有预柱的LKB Superpac ODSC_(18)钢柱上,使用离子对系统做为洗脱液,对一组正常活动规律的树鼩脑组织液中的去甲肾上腺素(NE)、多巴胺(DA)、5-羟色胺(5-HT)及色氨酸(TRP)进行测定。荧光检测的波长为激发波长280nm,发射波长360nm得到各物质最小检测限量为:40ng NE和80ngDA(信噪比3:1)以及10ng5-HT和15ng TRP(信噪比4:1)。此方法具有实验操作简单、方便、快速、灵敏度较高、样品易于处理等特点。
