“碳关税”对中国经济的潜在影响

近年来,一些发达国家以应对气候变化为由,提出对进口的碳排放密集型产品征收特别的CO2排放关税,并将"碳贸易限制措施"扩大为"碳关税"壁垒。"碳关税"的开征必然对我国经济、出口贸易造成严重冲击。因此,我们应该积极主动参与相关国际规则的制定,优化出口贸易结构,加强低碳技术创新,实现向低碳经济的转型,以便充分地应对"碳关税"壁垒。     

欠发达地区农民的科技意识现状及其影响因素——对广东省粤北山区和东西两翼430位农民的实证调查

科技意识是人们对科学技术的基本看法,它反映了人们对科技的认识及关心程度,是科技素质中最为基础与核心的心理要素。目前欠发达地区农民的科技意识较为淡薄,影响其科技意识提升的因素主要有文化制约、技术制约、效益制约和资金制约。完善农村的教育体系是培养农民科技意识的基本环节;增加农业科技的有效供给是提高农民科技意识的重要环节;抓好采用科技的经济环境是强化农民科技意识的关键环节。     

传统道德对政治文明建设的双重影响

传统道德中仁政爱民、重道尚义、立志与践履、克治与慎独的思想和品德等对执政党及其领导干部有积极的影响,同时,传统道德中官僚特权、宗法等级、重人治轻法治的思想和观念对执政党及其领导干部又有消极的影响。这种双重影响会导致党员干部执政能力的大小和执政水平的高低,进而直接推动或阻碍政治文明的发展进程。必须加强党员干部的思想道德教育,继承和发扬优秀的道德传统,反对和摒弃消极的道德传统,提高他们的思想道德素质,以利于政治文明建设。     

磁流变阻尼器结构设计及其阻尼特性试验研究

目前市场上的磁流变阻尼器由于阻尼力与体积过大而并不适用于滚筒洗衣机安装与控制,依据滚筒洗衣机悬挂 系统阻尼器力学性能以及磁流变液的材料特性和磁路设计原则,设计并制作了一个单出杆的剪切阀式磁流变阻尼器样 品,采用Instron 8800材料试验机对所设计的磁流变阻尼器进行特性试验,采集其在不同电流、频率和位移下的阻尼力。 采用MATLAB对实验数据进行处理,分析磁流变阻尼器的阻尼性能,结果表明该磁流变阻尼器设计是符合设计要求,可 用于滚筒洗衣机抑振控制策略的研究。     

《容斋随笔》对王安石形象的历史书写及其影响简

《容斋随笔》通过对王安石的个人形象、王安石政治及王安石学术的历史书写,形成了自己的王安石历史形象。《容斋随笔》阐释下的王安石历史镜像,既是当时主流意识形态的反映,同时也对当时及后世王安石的历史形象产生深远影响。     

基于 JCR 的不同学科类目文献计量学指标的统计与分析

基于2011年JCR网络版,对JCR所划分的176个学科类目的文献计量学指标,包括总被引频次、中值影响因子、学科集合影响因子、学科集合立即指数、学科集合被引半衰期、学科期刊数和学科总文章数,进行了统计与分析.结果表明：不同学科类目计量指标差异很大.建议在学术期刊评比和科研绩效评价时,应使用相对指标来消除学科之间的差异.     

我国区域经济集聚的环境效应研究

区域经济集聚通常对地方的经济增长和城市化发展具有巨大的推动作用，但在生态环境方面的作用却相反。主要表现在三个方面：在区域内。经济集聚的环境效应会使地方环境问题目趋严重；在区域外。经济集聚引致了大规模的跨区域资源配置，这种跨区域的经济要素流动由于缺乏应有的生态补偿机制的配合，会将经济集聚的环境负效应扩散到资源流出地区，造成全局性的环境问题；在环境治理方面。现有的环境政策并不能减弱经济集聚的向心力与环境负效应，反而刺激了经济集聚，增加了集聚区域的经济总量和污染排放总量。结果，经济集聚的环境问题更加突出。并向区域外扩散，呈现出一种全局性的生态环境恶化趋势。     

A Probabilistic Methodology for the Assessment of Safety from Dropped Loads in Offshore Engineering

Pipeline damage by dropped objects from crane activities is a significant hazard for offshore platform installations. In this paper a probabilistic methodology is utilized for the estimation of the pipeline impact and rupture frequencies; this information is obtained both for the overall pipeline section exposed to the hazard and for a number of critical locations along the pipeline route. The presented algorithm has been implemented in a computer program that allows the analysis of a large number of possible drop points and pipeline target point locations. This methodology may be used in common risk analysis studies for evaluating the risk for platform personnel from dropped objects; however, the proposed technique may also be useful for other applications where engineering judgment has so far been the main driving criterion. In particular, two sample cases have been analyzed. The first one is the problem of selecting the best approaching route to a platform. By analyzing different route alternatives, a reduction of the impact frequency and therefore of the risk for the platform personnel may be achieved. The second application deals with the selection of the location for a safety valve at the riser base. The analysis may give useful information, such as the highest impact frequency location and the rupture frequencies upstream and downstream of the valve as a function of the valve position; this information, together with the transported medium inventory upstream of the valve, may give the designer a documented and justifiable rationale for selecting the best location for the valve from a safety point of view.     

Non-linear models 1

This is the first application of a new method for testing stationary random point processes. Consider the class of all stationary ergodic point processes on the real line with arbitrary dependences among the inter–point distances (spacing).The hypothesis is :The observed process φ is a homogeneous Poisson process or more (resp.less) regular than a Poisson process.The sample is the vector of the first n points t₁, …,t_n.There is a close relation between our method for testing and queueing theory: For finding an appropriate test statistic, we observe the behaviour of a single server queue with the input φ.A table of critical values is given.     

传统苗医药文化对苗药发展的影响

＂千年苗医,万年苗药＂,源远流长的苗医药及其文化,对现代苗医药的发展有着深刻的影响。救死扶伤、以人为本的行医用药理念,效果明显甚至有特效的医药方,广种药材的习俗等对苗医药的发展有着推动作用和积影响。而医药方秘不外传、医药师之间相互保密、闭关自守的传统做法以及至今仍存在的＂巫医合一＂现象等,则对苗医药的发展有着阻碍作用和...
