    近几年,中国汽车行业的繁荣带动着汽车电子行业飞速发展。车载信息娱乐系统也由原来单一的收音机、播放机功能发展到集成GPS,DVD、娱乐、通信等功能。一些主流的车载网络协议也渐渐的成为了国际上通用的标准。尽管目前国内自主品牌汽车上普遍都有安装车载信息娱乐系统和车载网络,但是其大部分的产品存在着功能少,用户体验差,可扩展性差,价格昂贵等缺点。本文针对国内外车载信息娱乐系统和车载网络存在的问题,通过高性能平台进行硬件系统设计,着重解决产品的功能集成度,可扩展性和用户体验等问题。 本文采用瑞萨电子的R-Car系列车载专用SoC作为信息娱乐系统的硬件平台,它拥有音频、视频、图形以及图像识别等多种功能,这...Automotive electronicsdevelops and expandsrapidly as automotive industry booms.In-Vehicle infotainment system had been changed from simple radio player to multi-function device with GPS, DVD, entertainment, communication etc. Some In-Vehicle network protocols became international standards.

    River Water Quality Assessment in Selected Yangtze Tributaries: Background and Method Development

    Get PDF
    Water pollution is among the most severe environmental problems in China, particularly in the vicinity of residential and urban areas. In almost all Asian countries, river monitoring is predominantly based on the analysis of chemical data. However, biological data are a worthwhile addition for the determination of the long-term ecological status of rivers and are particularly well-suited in case of steep pollution and disturbance gradients. A tool for river water quality assessment using benthic invertebrates has been developed for selected tributaries of the middle reach of the Yangtze River. Site selection was supported by a preclassification considering physico-chemical and hydromorphological conditions. Following a stratified sampling design, 34 samples were taken in small and large streams in the subtropical mountainous area of western Hubei (湖北) (China) covering a pollution gradient, accompanied by an extensive field protocol on stream characteristics and (physico-) chemical water analyses. The proposed assessment system is computed as an average score per taxon. The challenge to further consider the additional impact from global change into the development of such tools is discussed

    三峡水库水环境与水生态研究的进展与展望

    伴随着举世瞩目的三峡工程全面竣工,三峡水库于2010年正式进入年水位落差达30 m的正常运行阶段.水库湖沼学可为环境友好型大坝建设和水库可持续管理提供科学依据.本文在三峡成库8 a以来生态系统长期监测与研究的基础上,对三峡水库水环境现状进行了归纳和总结,分析了水环境动态的时空异质性、水库纵向分区与群落组成、垂向分布及藻类水华的成因和动态,并对三峡水库藻类水华预警与生态-水文调控机制展开了论述.最后,本文尝试给出以下两方面的展望:1)大型水库湖沼学观测研究应有长期的策略;2)近期研究应重点关注水华暴发水动力学机制的量化和水华预警模型及生态水力调度平台的耦合

    分区边界的确定是生态分区的重要步骤,但目前多数水生态分区的边界确定以定性分析、专家判断为主。本研究以洱海流域为例,建立了一套两级分区体系。该体系基于GIS技术,用子流域作为分区基本单元,并用相关分析法,定量筛选一、二级分区指标。其中,一级分区指标为高程、坡度和植被归一化指数(NDVI),二级分区指标为农田百分比和城镇百分比。通过指标图层的叠加和重分类,合并同质性子流域,从而将洱海流域划分为5个一级区和9个二级区。藻类群落分布的验证结果表明分区合理。本研究将定量分析和子流域边界应用于水生态分区,使分区边界的确定更科学,在实际管理中更具有可操作性。本研究结果为水生态分区研究提供了新的方法,为洱海流域水生态管理提供了基本管理单元

    产业集群发展已经在现代经济发展中起着非常重要的作用,产业集群战略已经成为许多国家和地区经济发展战略的现实选择。然而,近些年来,无论是已有产业集群的继续持续发展还是新的产业集群的打造,都面临着许多新的挑战特别是人力资源的支持方面挑战。本文运用文献资料法、调查研究法及案例分析法,通过对产业集群经典文献的回顾及国内现有研究的检索,注意到关于产业集群发展中的人力资源问题研究薄弱。本文紧密结合我国劳动力市场变化的现实及产业集群理论,将人力资源问题的微观企业层面同宏观产业层面紧密联系,分析了产业集群发展与人力资源集聚的辩证关系,认为产业集群中的人力资源集聚组织具有中观性、规模性、网络性等特点,强调了产业集...Industry cluster development in modern economic development plays a very important role, industrial cluster strategy has become a national and regional economic development strategy choice.
