This paper presents one of the future trends in analytical quality assurance, the evaluation of the quality of analytical results by estimation of their uncertainties. The present state-of-the-art is described, and the impact caused by the declaration of uncertainties in chemical results is foreseen. 相似文献

基于余淼杰和张睿的企业−产品层面出口质量测算方法,通过对2001−2006年出口目的国及中国工资增速对中国出口产品质量增速影响的实证检验,结果发现:目的国工资增长对中国出口产品质量增速的贡献主要源于发达国家而非发展中国家,体现了“富国效应”,行业类型不影响该结论;就作用机制来看,发达国家外溢效应主要通过要素替代效应而非收入效应实现,由此解释了发展中国家工资增长对中国出口产品质量增速不具有显著贡献的原因,并且,发达国家外溢效应通过出口产品的进入−退出机制实现,持续出口的产品质量增速未获得显著提升。此外,中国广义工资增长对出口产品质量增速的贡献具有普适性,体现了本国竞争效应。上述结论体现了入世初期中国作为劳力丰富型国家在全球价值链中的“世界工厂”地位,也表明了在当前人口红利消退的大背景下中国外贸转型面临着一定的挑战。 相似文献

通过对目前分析化学教学中存在问题的分析,探究了新工科背景下分析化学专业中关于质量保证和质量控制方面的教学改革,提出了增设“分析化学中的质量保证和质量控制”或者类似的课程的建议,指出分析化学的教学应该围绕整个分析过程展开,并将分析化学中的质量保证和质量控制知识融入分析全过程中,注重理论课程与实践课程相互结合的同时更加强调应用性,增强学生的实践能力和分析问题、解决问题的能力。此外,分析化学教学重在“分析”,要与分析实验室/检测机构保持紧密联系,应建立以市场为导向、以技术为核心的教学活动,从而实现为社会不断培养与时俱进的分析人才的教育目标。 相似文献

The effects of quality-management systems on external quality-assessment performance in Finnish clinical chemistry laboratories 总被引:1,自引:0,他引:1

The effects of the implementation of quality-management systems and technological changes on the performance of 23 Finnish clinical chemistry laboratories were studied in external quality-assessment (EQA) schemes organized by Labquality Ltd., Finland, during 1993 to 1999. The investigated serum analytes were sodium, calcium, glucose, cholesterol, and alanine aminotransferase. According to the results, the improvements in analytical quality due to the quality programs were rather small. The effects to the proportions of satisfactory results in terms of precision and deviation from the target value were 5–15% (95% confidence intervals for the proportions ±1–5%). At the same time the laboratories were implementing quality-management systems new technology and characteristics of quality-control materials affected the EQA performance. Both improvements and deteriorations in analytical quality due to these factors were identified. The effects and their total outcomes differed substantially between the five analytes. 相似文献

General criteria for the operation of testing laboratories according to standards series EN 45000 and quality assurance under
ISO series 9000 are discussed, and other quality management systems too are presented. The important elements of quality assurance
as concerns measurements, tests and investigations are pointed out.

Ladybug taint (also known as ladybird taint) is a relatively recently recognized fault that has been identified in wines from a wide range of terroirs. Alkyl-methoxypyrazines—particularly 2-isopropyl-3-methoxypyrazine—have been determined as the causal compounds, and these are introduced into grape must during processing, when specific species of vineyard-dwelling Coccinellidae are incorporated into the harvested fruit. Coccinella septempunctata, and especially the invasive Harmonia axyridis, are the beetles implicated, and climate change is facilitating wider dispersal and survivability of H. axyridis in viticultural regions worldwide. Affected wines are typically characterized as possessing excessively green, bell pepper-, and peanut-like aroma and flavor. In this paper, we review a range of vineyard practices that seek to reduce Coccinellidae densities, as well as both “standard” and novel wine treatments aimed at reducing alkyl-methoxypyrazine load. We conclude that while prevention of ladybug taint is preferable, there are several winery interventions that can remediate the quality of wine affected by this taint, although they vary in their relative efficacy and specificity. 相似文献
