关键词： 金相检验   发展   重要性  

摘要： 经济建设的不断创新与发展,汽车行业的不断壮大以及工业机械的快速发展,在一定程度上带动了特钢行业的发展进步。但是随着各种新技术以及高端设备的不断出现,对于特钢行业而言要求其质量不断提升以及自主创新的能力越来越强,为了适应时代社会发展的需要,满足其质量要求,特钢行业必须加强自主创新的能力。总体而言,就我国目前特钢产量而言,还是具有一定优势的。文章主要针对金相检验技术在特钢中的重要应用进行简要分析与总结,以此推动特钢行业的发展建设,真正意义上促进国民经济建设的发展。

关键词： 微生物检验   医院感染  

摘要： 目的探讨分析微生物检验在医院感染控制中的地位及作用。方法选取2014年1-12月与我院住院进行治疗的130例患者作为研究对象,随机分为常规组（n=65）和检验组（n=65）。常规组给予药物等常规治疗,而检验组在常规组的基础上给予微生物检验,观察两组患者感染发生情况。结果常规组轻度、中度和重度感染分别为10.8%、4.6%和3.1%,检验组分别为3.1%、1.5%和1.5%,两组间比较无统计学差异（P均〉0.05）,而检验组的总感染率为6.2%,明显低于常规组18.5%的总感染率,比较有统计学差异（P〈0.05）。结论微生物检验可以预防医院感染,降低感染发生率,在医院感染控制中具有重要地位和作用。

关键词： 块菌   电子鼻   电子舌   主成分分析   传感器  

摘要： 采用电子鼻嗅觉指纹分析系统、电子舌味觉指纹分析系统对不同种类块菌及其加工后样品进行识别,对传感器所收集的数据进行主成分分析、判别因子分析。结果表明:电子鼻技术能够有效识别不同种类块菌,并能够明确区分不同加工方式下的8个块菌样品;电子舌能够将不同种类块菌的新鲜和干燥样品区分开,对不同种类块菌的新鲜样品具有较好的识别和区分能力,但对干燥后的块菌样品识别能力较差,使用判别因子分析比主成分分析更有优势。此研究表明,电子鼻和电子舌均可用于块菌样品的识别,只是识别范围不同。

摘要： 纺织纤维的种类繁多,纺织纤维制品就更为丰富。由于纤维制品不同的使用目的,在其加工过程中又赋予了一些功能性的工艺处理,使得纤维制品检验项目既有物理性能的检验还有化学分析方面的检验。本文从现有的纤维及其制品检验项目入手,对检验过程中使用到的各种标准样品进行分类归纳,着重说明分模块建立纤维及其制品检验标准样品查询系统的重要性。纤维及其制品的检验项目随着科技的进步,检测技术也随之不断地发展,

关键词： 生化检验结果   临床生化检验   标本溶血   日常工作   水浴温度   细胞破坏   监测结果   经济负担  

摘要： 溶血是检验科临床生化检验常发生的影响和干扰，在日常工作中，有很多原因可以导致此种现象，如试管不洁、过度震荡或摇晃、采血过快、检验中水浴温度过高以及采血时进入了空气等。一旦发生标本溶血，不仅会破坏红细胞，还会干扰白细胞和血小板等细胞破坏释放的物质，影响监测结果，可能造成患者多次重复就诊，增加患者经济负担，甚至可直接导致医师误诊而发生意外情况。

关键词： devices   extractables   leachables   parenteral packaging   safety assessment  

摘要： To develop and justify a Risk Evaluation Matrix for estimating the safety risk associated with extractables from plastic materials used in pharmaceutical applications and to apply that matrix to approximately 510 extractables to assess the risk that they would accumulate in drug products at levels sufficiently high to affect patient safety. The Risk Evaluation Matrix considers toxicological, availability and solubility characteristics of extractables. Safety Risk categories were established based on certain scaled values for these characteristics, Total Risk Scores were calculated for each extractable and the extractables were categorized with respect to their safety risk based on these calculations. The Total Risk Scores were normally distributed around a value of 20 to 23, corresponding to safety risk categories of moderate and intermediate risk. The range in Risk Scores defined by the mean +/- one standard deviation encompassed the entire region of moderate and intermediate risk. Approximately 15% of the extractables were categorized as lowest risk while 3% of the extractables were categorized as highest risk. Categorization of extractables could facilitate the selection of materials for use in pharmaceutical systems, the analytical testing of extracts and the selection of target extractables.

摘要： Laboratory medicine is an indispensable part of medical field, which is combined clinical medicine and medic laboratory technology. With the feature of gambit lately but developing spanking, laboratory medicine have been faced with lots of difficulties and challenges after it founded, and since Ministry of Education has implemented reform of laboratory education in 2012, it has become an urgent priority to find a reasonable teaching method as well as the outlet of this discipline. Although medical professional accreditation is a newly started undertaking in China, it has already become a tendency in medical education. As to the advantage of the Professional Certification, we are convinced that implementing accreditation of medical laboratory technology helps to ensure the quality of education,deepen educational reform, fill social requirement of laboratory talents and promote internationalization of this major.

关键词： Acoustic emission   Carbon fibres   Unsupervised learning   DAMAGE  

摘要： Widespread use of composites for structural applications is hindered by the inability to fully understand and predict the materials response. The uncertainty in composite materials response is largely due to variability in the initiation and propagation of damage. To develop new tools for design with composite materials, techniques for identifying damage modes during operation are needed. While there is a large body of work on analysis of acoustic emission (AE) from different materials and different loading cases, the current research is focused on applying unsupervised learning for separating AE into a maximum number of groups with distinct evolution. AE data was collected during tensile and bending experiments on carbon fiber reinforced epoxy specimens with different material configurations. The unsupervised learning algorithms successfully identified AE groups with distinct initiation and evolution. With damage mechanisms inferred from load response and from deformation fields obtained with digital image correlation (DIC), strong correlations between the behaviors of the groups and the damage mechanisms were observed and are discussed.
