知识和经验对救援人员实战心理的影响分析

为了解影响救援人员实战心理的关键因素及其作用,采用走访、专家访谈和问卷调查的方法,对我国消防部队的人员组成、心理状况和实战心理进行调查和研究,重点分析消防队员掌握灾害知识和经验积累对实战中出现的恐惧、紧张、急躁等心理的影响。研究结果表明,灾害知识和救援经验的增加对大部分消防队员均能起到消除紧张情绪的作用,知识水平和实战中的紧张与恐惧心理呈现明显的负相关,且影响显著。笔者认为:将救援队伍和人员的灾害知识培训纳入日常工作,对提高救援部队的总体作战能力具有重要作用;对于高级指挥人员,理论知识水平的提高有助于更佳的指挥应对。     

家具企业安全管理调查研究——运用行为抽样法调查分析不安全行为

为降低家具企业事故的发生概率,通过对家具企业机加工车间工人的不安全行为的观察,依据其主要表现,将工人的不安全行为分为静态和动态两类;运用行为抽样法对生产现场工人的不安全行为情况进行的抽查,并对其不安全行为进行现状评价;通过分析不安全行为发生的原因,提出相应的改进措施。     

The humanitarian common logistic operating picture: a solution to the inter‐agency coordination challenge

Although significant progress has been made in developing the practice of humanitarian logistics, further improvements in efficiency and effectiveness have the potential to save lives and reduce suffering. This paper explores how the military/emergency services’ concept of a common operating picture (COP) can be adapted to the humanitarian logistics context, and analyses a practical and proven approach to addressing the key challenge of inter‐agency coordination and decision‐making. Successful adaptation could provide the mechanism through which predicted and actual demands, together with the location and status of material in transit, are captured, evaluated, and presented in real time as the basis for enhanced decision‐making between actors in the humanitarian supply network. Through the introduction of a humanitarian logistics COP and its linkages to national disaster management systems, local communities and countries affected by disasters and emergencies will be better placed to oversee and manage their response activities.     

如何确定高加速寿命试验的应力极限

气锤驱动的高加速寿命试验,主要目的是确定试验样品的应力极限(包括工作极限和破坏极限),并通过改进试验所暴露的缺陷,按预期目标拓宽产品的应力极限。本文对一些应力极限的名词术语作了解释性说明,并具体论述了如何确定应力极限及快速温变循环试验的高低温温度极值。     

反渗透膜处理维生素C凝结水的最优工艺条件

针对维生素C生产工艺中产生的凝结水产量大、处理成本高、存储运输困难和营养物质含量偏低等问题,采用反渗透技术对VC凝结水进行处理。实验建立小试规模反渗透膜处理装置,采用无量纲化多元回归分析方法,分析了操作条件指标与渗透水评价指标两套指标体系之间的关系,定量评价了各个操作条件指标对渗透水评价指标的整体影响程度,并在此基础上研究了最佳操作条件的工艺参数。结果表明：建立的无量纲化多元回归分析方法切实有效,在正交实验设计水平范围内,压力、pH和回流比均是多目标系统的影响因子,操作条件指标对渗透水评价指标的整体影响程度大小顺序为：压力〉pH〉回流比〉温度,且各自影响程度所占比例分别为43．02％、29．01％、25．07％和2．89％。各个操作因子对多指标系统的影响是独立的。在只考虑系统收益而不考虑膜污染的情况下,最佳操作条件分别为：温度r=30．65,压力P=1．5MPa,回流比r=0．78,pH=7．475。     

基于虚拟样机的自卸汽车卸载作业侧翻分析

针对自卸汽车卸载作业时发生的侧翻问题,分析影响自卸汽车作业安全的因素.根据自卸汽车结构及其作业特点,建立自卸汽车整车虚拟样机模型.采用多体系统动力学分析软件(ADAMS),对自卸汽车在不同横向坡度卸载作业的安全性进行仿真分析,得到自卸汽车安全作业的举升角与路面横向坡度、装载重量间的关系.结果表明,一定载荷条件下,横向坡度越大,临界举升角越小; 横向坡度相同时,载重越大,临界举升角越小; 未正常卸载工况的临界举升角小于正常卸载工况的.本研究为减少或避免自卸汽车卸载作业时的侧翻事故提供了参考依据.     

A RISK-BASED MODEL FOR DROUGHT CONTINGENCY PLANNING1

ABSTRACT: A risk-based model is presented for determining action levels in real-time operation of public water supplies under drought conditions. The model, applicable to surface water supplies, is built around the almost universally adopted structure for drought management, a sequence of increasingly stringent measures to reduce demand. Action levels are determined by finding minimum storage levels that will satisfy a prescribed set of probability constraints over the remainder of a drawdown-refill cycle. Results are presented for the City of Raleigh, NC.     

体育旅游产品消费的文化背景

人们的消费具有社会性,因而具有很强的时代性。在国内外兴起并迅速发展的体育旅游产品是时代的产物,它是休闲时代人们消费的主体产品,是体验经济时代旅游产品的升级换代产品。人们通过消费体育旅游产品,不但能休闲、娱乐、健身、交际,还能发展自己、完善自己、实现自我价值,从而迎合了知识经济时代人们消费的价值观。我国有极其丰富优越的体育旅游资源,关注并开发体育旅游市场是我国旅游业可持续发展的重要战略。     

MULTIOBJECTIVE DECISION MAKING TECHNIQUES FOR RESERVOIR OPERATION1

ABSTRACT: Six applications of multiobjective decision making techniques for finding optimal or satisfying operating rules for reservoir systems are presented. The examples include situations with hydropower vs. water supply (for irrigation), flood control vs. low flow augmentation, selection of an operating rule, low-flow vs. reliability, and low flow and recreation vs. water quality. The techniques applied include the constraint method, compromise programming, goal programming, Tchebycheff approach (max-mm), Consensus, and ELECTRE I and II.
