办公空间人性化设计研究

&lt;p&gt;办公空间的人性化设计就是空间中的环境与工作人员的活动不发生冲突，且是最优的一种空间方案设置，让人们享受工作的愉悦和乐趣，使得人性充分的释放，心理更加健康，情感更加丰富。现代办公空间室内环境设计的宗旨是以人为本，更是人与人、人与社会、人与自然和环境关系的重构和利用。文章就办公空间人性化设计进行分析探讨。&lt;/p&gt;</jats:p

时空众包数据管理技术研究综述

近年来,众包为传统数据管理提供了一种通过汇聚群体智慧求解问题的新模式,并成为当前数据库领域的研究热点之一.特别是随着移动互联网技术与共享经济模式的快速发展,众包技术已融入到各类具有时空数据的应用场景中,例如各类O2O(online-to-offline)应用、实时交通监控与动态物流管理等.简言之,这种应用众包技术处理时空数据的方式称为时空众包数据管理.对近期在时空众包数据管理方面的研究工作进行综述,首先阐述了时空众包的概念,解释了其与传统众包技术的关系,并介绍了各类典型的时空众包应用;随后描述了时空众包应用平台的工作流程及其任务特点;然后讨论了时空众包数据管理的3项核心研究问题和3类应用技术;最后,总结了时空众包数据管理技术的研究现状并展望了其未来潜在的研究方向,为相关研究人员提供了有价值的参考.In recent years, crowdsourcing, which utilizes the intelligence of crowds to solve problems, provides a novel data processing paradigm for traditional data management challenges and has become one of the hottest research topics. In particular, due to the rapid development of mobile Internet and sharing economy, crowdsourcing not only becomes a new approach for data collection, but is also integrated into all kinds of application scenarios especially spatiotemporal data management such as online-to-offline (O2O) applications, real-time traffic monitoring, and logistics management. In this paper, a survey is provided on existing research of spatiotemporal crowdsourcing. First of all, the concept and representative applications of spatiotemporal crowdsourcing is described, and its relationship with traditional crowdsourcing is explained. Then, the workflow of spatiotemporal crowdsourcing is illustrated. Furthermore, three core research problems and three categories of techniques of spatiotemporal crowdsourcing are discussed. Finally, the state-of-the-art studies of spatiotemporal crowdsourcing are summarized and promising future research directions for the research community are presented. © Copyright 2017, Institute of Software, the Chinese Academy of Sciences.

飞灰辐射特性与表面温度关联的实验研究

为降低燃煤、垃圾焚烧和生物质锅炉高温换热器传热管失效泄漏甚至爆管的风险,提出基于高温内窥镜光学测温方法的高温换热器表面积灰和温度状态监测系统。采用多元扩散Hencken燃烧器和细颗粒振荡给粉技术,开展了3种飞灰可见光段辐射特性与温度的关联规律研究。结果表明:由于3种飞灰理化性质不同,其辐射-温度关联曲线区别明显;光学频道选择不同也会显著影响结果的准确性,在实际应用前应进行系统的实验室标定,以获取更为精确的结果

碳纳米管负载铑催化剂上丙烯氢甲酰化

Effect of carbon nanotubes, as a novel support material, on the performance of Rh-catalyst supported by them was studied. Catalysts based on carbon nanotubes, SiO2, carbon nlolecular sieves, actiye carbon, and GDX-lo2(a copolymer of styrene with divinyIbenzene),were prepared, and their catalytic behaviors for propene hydroformylation were investigated and compared. The results showed that, over the carbon nanotubes-supported Rh-catalyst, C3H6 conversion and regioselectivity of butyric aldehyde (represented by n/i, a ratio of n-butyric aldehyde to its isomer, i-butyric aldehyde, in the products) were pronouncedly improved: the average turnover frequency(TOF) for the catalytic hydroformylation of propene was 0.079 s-1 at 393K, which was 2.1 times faster than that over the Wh catalyst based on SiO2, and the n/i ratio of the aldehyde products reached to 11.6, which was 1.9 times higher than that over the catalyst based on SiO2.The roles of six-membered C-ring at the surface of the carbon-nanotubes on the stabilit..
