Mg2Sn对镁合金耐腐蚀性能影响的计算分析与验证

目的 从计算角度分析镁合金中的主要析出相Mg_(2)Sn对ZA系镁合金耐蚀性能的影响,并采用试验测试的方法对其进行验证。方法 利用第一性原理计算方法对Mg_(2)Sn的表面能与功函数进行计算,通过与构建的Mg基体以及Zn、Al掺杂的Mg表面的表面能、功函数进行对比分析,分析Mg_(2)Sn对ZA系镁合金耐蚀性能的影响。为了验证计算结果,制备Mg-5Zn-3Al-0Sn合金以及Mg-5Zn-3Al-3Sn合金,通过电化学实验对2种合金的耐蚀性能进行对比分析,研究Mg_(2)Sn对ZA系镁合金耐蚀性能的影响。结果 计算了Mg基体表面能与功函数,与其他成果计算结果的符合程度较好。对Mg_(2)Sn不同表面的功函数进行计算,通过与Mg、Mg-Zn、Mg-Al表面的计算结果进行对比,发现Mg_(2)Sn的功函数均要更高。XRD测试结果表明,制备的Mg-5Zn-3Al-3Sn合金中有明显的Mg_(2)Sn相。电化学测试结果表明,Mg-5Zn-3Al-0Sn的耐蚀性能要好于Mg-5Zn-3Al-3Sn的耐蚀性能。结论 通过第一性原理计算发现,Mg_(2)Sn的功函数高于Mg基体表面的功函数,说明在合金中易发生微电偶腐蚀,Mg_(2)Sn充当阴极相促进Mg基体的腐蚀。电化学测试结果说明,当合金中存在明显的Mg_(2)Sn相时,合金的耐蚀性能降低,腐蚀电位达到-1.21 V。     

飞行器雷电间接效应危害及其防护研究

雷电对飞行器的损伤作用分为直接效应和间接效应,间接效应可能导致内部电子电气设备及系统功能紊乱或丧失。本文在分析雷电特性的基础上,应用理论分析和计算的方法,探究了飞行器雷电间接效应的作用机理,并结合GJB 1389A[1]、GJB 2639-1996[2]等标准对间接效应试验和雷电防护方案进行了设计。     

The role of safe work method statements in the Australian construction industry

The aim of this study was to determine how managers and workers interpret and use safe work method statements (SWMS) in the Australian construction industry in order to explore if there was a gap between work as imagined and work as performed. Despite recent improvements in its safety performance, the Australian construction industry continues to be among the top four most dangerous industries within which to work. SWMS are a key strategy relied upon by the construction industry to reduce this toll. However, few, if any studies have looked at the role of SWMS in creating a safe workplace. This ethnographic study focused on the role of SWMS at two commercial construction sites in Australia. The researcher spent 6 months ‘getting to know’ the organisation before conducting 18 semi-structured interviews spanning labourers, supervisors and managers. The researcher also collected examples of completed SWMS. This study found: (1) that SWMS are important for safety, particularly for tasks that are out of the ordinary; (2) that social interaction as well as SWMS are important for safety; (3) gaps do exist between work as imagined in a SWMS and work as performed in practice, but in the minds of those on site, there were no unresolved gaps; (4) therefore construction companies must identify and resolve the gaps between SWMS, practice and task demands to make construction sites a safer place to work.     

企业安全生产组织行为的长效机制探讨

为探求企业安全生产组织行为长效机制的形成,基于企业“经济人”的假设,通过建立认知不完全条件下企业安全生产组织行为的基本效用模型,分别在有效贯彻执行安全生产法规和严格遵循沿袭企业内在安全文化的条件下,分析了企业安全生产组织行为效用模型的变化.结果表明,强制性地贯彻和执行安全法规,能够有限内化企业安全生产组织行为的持续;强化企业的安全智识素质和责任素质,能够激发和促进企业安全生产组织行为的持续形成,并沉淀为企业内在的安全文化;但只有外在有效强制规控安全法规、内在内导强化企业安全文化共同作用下,企业安全生产组织行为的长效机制才能得到持续确立.     

发达国家农业安全管理现状分析及对我国的启示

我国正处于农业快速发展的新时期,需要借鉴发达国家经验,提高农业安全监管能力,促进农业生产安全水平提升。本文对美国、澳大利亚、英国、日本等各国近20年农业产业职业安全健康水平进行分析,从立法、监管范围、监管机制、教育培训等方面梳理其职业安全健康工作,同时剖析其农业安全管理经验和存在的主要问题,以此从法规标准、监管体制、基础建设、教育培训等方面提出优化提升我国农业安全生产工作的意见建议。     

Visual disturbances with cholinesterase depletion due to exposure of agricultural pesticides among farm workers

In this study, risk assessment for visual disturbances among farm workers spraying agricultural pesticides in farms have been assessed. A cross-sectional study for the assessment of visual disturbances was undertaken using questionnaire survey and clinical examination among agricultural workers exposed to pesticides. Two hundred and thirty nine pesticide sprayers participated in the study. The study was compared to 110 controls not occupationally exposed to pesticides with similar socio-economic status. The prevalence of ocular morbidity was found to be 40% among pesticide sprayers which was significantly higher (p?p?相似文献
