| 2 | Oxidation and Thermal Fatigue Behaviors of Two Type Hot Work Steels During Thermal Cycling显示文摘Thermal fatigue test has been carried out on widely used hot work steel 4Cr5MoSiV1and a low alloyed steel 3Cr3MoV in temperature range of 200to 700℃.Tempering resistance,as well as high temperature hardness/strength of steel specimens,works as a dominating material parameter on thermal fatigue resistance.During the heating period,high hardness can depress the inelastic deformation.This deformation is the origination of tensile stress,which acts as the driving force of heat checking during the cooling period.The cyclic strain-oxidation interaction can speed up the damage on surface defects,which plays an obvious role in initiation of thermal cracks.On4Cr5MoSiV1steel specimens,borders between the matrix and inclusions such as titanium compounds,or lager carbides such as primary carbides,are focused by strain and attacked by oxidation,and are main initiating places of cracks.While on 3Cr3MoV steel specimens,larger strain causes plastic deformation concentrating around grain boundaries.Then the following oxidation accelerates this grain boundary damage and creates cracks. | MIN Yong-an Bergstrm Jens WU Xiao-chun XU Luo-ping | 2013 | Journal of Iron and Steel Research(International)2013，20，11： | 5 |
| 3 | 化学物质在土壤中的环境归宿显示文摘通常,人们利用短期的室内试验结果,结合化学物质的降解、物理/化学性质来研究土壤中化学物质的环境归宿。只要化学物质溶解,或是处于与土壤固液相平衡的状态,这些数据或研究结果就可以应用。但是,越来越多的证据表明,要描述化学物质在自然环境中的迁移转化规律,还必须考虑不同尺度的土壤结构,以及降解、吸附/解吸、运移等非平衡过程的影响。以化学物质的淋溶为例,由于能有效地模拟田间状况,在非稳态条件下的田间蒸渗试验是室内试验很好的替代方法。本文介绍了几种利用稳定性田间蒸渗仪和室内分析的方法,研究化学物质降解动力学的实例。重点是与根据化合物的内在(标准)理化性质得出的迁移转化规律进行比较,并提出应用这些性状作为模拟模型的输入参数可能遇到的问题。 | Lars Bergstrm John Stenstrm 史雅娟 | 1998 | 人类环境杂志1998，27，1： | 2 |
| 4 | 条件磷指数:一个用于风险评估和磷管理的教育工具显示文摘磷指数(PI)是一个结合磷源因子和传输因子来对土地磷流失的脆弱性进行分类的风险评估工具。本文阐述了条件磷指数的结构和概念,用来作为教育和磷管理的有效工具,加以调节后可以用来对瑞典的实际环境条件进行评估。由于某一特定因子对磷流失的重要程度强烈依赖于他们同其他因子的相互影响作用,更为精确的过程描述和量化的条件规则是必不可缺的。考虑通过土壤剖面磷的流失,单独计算活性磷和惰性磷,用动态的方法来计算土壤侵蚀流失中磷的流失评价,是本文提出的教育和管理工具的一些全新的特征。通过比较计算的PI值和从一个瑞典水质监测项目中7个观测地点观测的磷年传输数据,对本文提出的方法进行测试。首次测试表明,这个方法能够成功地用于磷流失风险评估。 | Faruk Djodjic Lars Bergstrm 李龙辉 | 2005 | AMBIO-人类环境杂志2005，34，4： | 1 |
| 5 | 西岸地区巴勒斯坦妇女的孕产妇死亡率显示文摘Objective: To assess maternal mortality and determine the most common causes of maternal death among Palestinian women. Methods: Available data on the 431 women who died between the ages of 15 and 49 years in the West Bank in 2000 and 2001 were reviewed. The data were collected from official agencies and, using the verbal autopsy approach, interviews of the deceased women’s relatives. The interviews were conducted in all 10 districts of the West Bank over 30 months. Results: Maternal mortality ratios for 2000 and 2001 were 29.2 and 36.5 per 100,000 live births, respectively. Cardiovascular diseases and hemorrhage were the most common causes of death. Misclassification was found in 38% of the deaths. A tentative analysis of avoidability indicated that 69% of maternal deaths could be classified as avoidable. Conclusion: A majority of thematernal deaths identified were avoidable. Substandard classification of maternal deaths is hampering efforts to reduce maternal mortality. | Al-Adili N. Johansson A. Bergstrm S. 朱国栋 | 2006 | 世界核心医学期刊文摘(妇产科学分册)2006，0，11： | 0 |
| 6 | 青光眼成本效益分析:影响功用的因素-来自瑞典的初步研究显示文摘Purpose:To investigate the effect of different levels of visual field defect in glaucoma on utilities and to test if utilities could be assessed using a general questionnaire such as the EQ-5D.Methods:cross-sectional study in 199 patients with ocular hypertension or open-angle glaucoma grouped into 5 severity stages according to visual field defects was performed in 4 specialized ophthalmic centres.Descriptive analysis was performed for the sample and by stage,and the effect of vision loss on utility was investigated with multiple step-wise regression analysis.Results:The mean age of the sample was 70 and the mean MD in the worse eye was-13.1 dB(SD 10.2).Visual acuity(VA)was 0.63 and 0.87 in the worse and better eye,respectively,and the mean utility was 0.80(SD 0.23).Utility decreased with increasing glaucomatous damage,ranging from 0.84 for mild disease to 0.72 for severe damage(MD-2.5 to-28.1),but the difference between the groupswas not statistically significant when controlling for co-morbidity,except for the most severe stage(p < 0.01).In multiple regression analysis,visual field in the better eye was significantly correlated with utility,and therewas an indirect correlation between visual field in the worse eye and utility:the effect of total VA on utility was significant,and MD in the worse eye was correlated with total VA.Conclusions:Utility is strongly correlated with overall vision.Our results suggest a relationship between glaucomatous damage and utility,and patients with severe damage have a significantly lower utility.However,this should be further investigated in larger samples that include more patients with moderate-severe bilateral damage. | Kobelt G.

| 7 | 耕作和混合农业体系未来植物养分利用的前景和挑战显示文摘在不污染环境的情况下生产足量的健康食品对未来世界农业是一个严重挑战。瑞典'21世纪的食物'研究计划已经研究了可持续耕作体系的经济的、环境的以及社会的各个方面,本文列举了瑞典'21世纪的食物'研究计划以及其它相关的国际研究计划中注重改善养分利用效率的一些研究,特别是氮和磷。它表明有许多可持续性解决养分利用效率的方法,有些很复杂,但有些就很简单。政府政策包括津贴、研究和技术以及公众对耕作方式的认可,所有这些都与制定这些解决方法结合在一起。需要知识转让的参与式途径,这样科学家、政策决策者、农场主、顾问以及消费者们可以交流信息,一起构建可持续的耕作体系。 | Lars Bergstrm Keith W.T.Goulding 张秋英 | 2005 | AMBIO-人类环境杂志2005，34，4： | 0 |
| 8 | Improved cryopreservation of human hepatocytes using a new xeno free cryoprotectant solution显示文摘AIM:To optimize a xeno-free cryopreservation protocol for primary human hepatocytes.METHODS:The demand for cryopreserved hepatocytes is increasing for both clinical and research purposes.Despite several hepatocyte cryopreservation protocols being available,improvements are urgently needed.We first compared controlled rate freezing to polystyrene box freezing and did not find any significant change between the groups.Using the polystyrene box freezing,we compared two xeno-free freezing solutions for freezing of primary human hepatocytes:a new medium(STEM-CELLBANKER,CB),which contains dimethylsulphoxide(DMSO) and anhydrous dextrose,both permeating and non-permeating cryoprotectants,and the frequently used DMSO-University of Wisconsin(DMSOUW) medium.The viability of the hepatocytes was assessed by the trypan blue exclusion method as well as a calcein-esterase based live-dead assay before and after cryopreservation.The function of the hepatocytes was evaluated before and after cryopreservation by assessing enzymatic activity of 6 major cytochrome P450 isoforms(CYPs):CYP1A2,CYP2C9,CYP2C19,CYP2D6,CYP3A4 and CYP3A7.RESULTS:The new cryoprotectant combination preserved hepatocyte viability significantly better than the standard DMSO-UW protocol(P < 0.01).There was no significant difference in viability estimation between both the trypan blue(TB) and the Live-Dead Assay methods.There was a correlation between viability of fresh hepatocytes and the difference in cell viability between CB and DMSO protocols(r 2 = 0.69) using the TB method.However,due to high within-group variability in the activities of the major CYPs,any statistical between-group differences were precluded.Cryopreservation of human hepatocytes using the cryoprotectant combination was a simple and xeno-free procedure yielding better hepatocyte viability.Thus,it may be a better alternative to the standard DMSO-UW protocol.Estimating CYP activities did not seem to be a relevant way to compare hepatocyte function between different groups due to high normal variability between different liver samples.CONCLUSION:The cryoprotectant combination may be a better alternative to the standard DMSO-UW protocol in primary human hepatocyte cryopreservation. | Mohammed Saliem Frida Holm Rosita Bergstrm Tengzelius Carl Jorns Lisa-Mari Nilsson Bo-Gran Ericzon Ewa Ellis Outi Hovatta | 2012 | World Journal of Hepatology2012，4，5： | 2 |
| 9 | 瑞典区域气候模拟计划(SWECLIM)综述显示文摘瑞典区域气候模拟计划(SWECLIM)是一个历时6年半的国家研究网络计划,该研究网络主要涉及区域气候模拟、区域气候变化预测以及水文影响评估,并且为广大的利益相关人士提供相应信息。大部分研究活动主要针对北欧区域气候系统。最终促使建立一个先进的大气-海洋-水文相耦合的区域气候模型系统和一套区域气候变化预测体系,并促成了相关数据的积累和相关过程研究的进步。反过来,作为对不同社会部门影响分析的一个起点,这些也可以用来作为信息源和为教育服务,而且还为国际气候研究做出了贡献。 | Markku Rummukainen Sten Bergstrm Gunn Persson Johan Rodhe Michael Tjernstrm 占车生 | 2004 | AMBIO-人类环境杂志2004，33，4： | 1 |
| 10 | 螺旋齿轮与正齿轮的表面致密化显示文摘过去几十年,用于汽车的粉末冶金零件不断增长,对零件性能的要求也越来越高。汽车用的变速器齿轮的形状复杂,按照齿轮质量要求(DIN,ISO,AGMA等)几何精度很高,按齿面与齿根的耐久性要求力学性能也很高。对于制造复杂形状零件,粉末冶金法对控制成本很有效。通过增加对齿的选择性致密化,在增加很少费用下就能满足精度与力学性能要求。由压制、烧结、碾压致密化及最后热处理组成的工艺路线,可评估用粉末冶金制造的变速器齿轮的可行性。在研究中所用的螺旋齿轮与正齿轮,对致密化及所得到的齿轮的质量与齿根疲劳都进行了试验。 | Sven Bengtsson Linnéa Fordén Magnus Bergstrm Claes Kuylenstierna 亓家钟 | 2009 | 粉末冶金技术2009，27，1： | 1 |
| 11 | “21世纪的食物”:寻找增进食物链可持续性的措施和工具的研究计划显示文摘'21世纪的食物',是一项包括整个农业食物链的跨学科研究计划,于1997~2004年在瑞典实施。该研究所面临的挑战是为整个食物链中存在的不可持续的活动提出环境分析工具和解决方案。这需要科学家和食物链利益相关人紧密合作。本文提出了一整套以可持续食物生产为特征的目标方案。综合和系统分析是用来分析拟定变化的可持续性的主要工具。在本文中我们对'21世纪的食物'的概念进行概述,同时着重说明一些结论。例如,我们发现:就环境影响和产品质量而言,总体上来说,有机农业及其产品并不比常规的产品和方法优越。项目所采用的一些管理经验非常独特,这也是项目成功完成的重要原因,所以本文中我们对此也进行了总结。 | Rune Andersson Bo Algers Lars Bergstrm Kerstin Lundstrm Thomas Nybrant Per-Olow Sjdén 张德亮 | 2005 | AMBIO-人类环境杂志2005，34，4： | 0 |
| 12 | 提高农业种植体系有机物质中氮利用的可能性研究显示文摘土壤有机养分源中的氮释放受许多因子的影响,如土壤温度和水分、有机物质的化学组成。在某种程度上,控制有机物质的化学组成可以增加氮释放和植物需求的同步性,而气候因子是不能控制的,因此在计划管理措施时要考虑这些因素。本文通过调节新鲜或预处理过的植物材料和牲畜粪肥的化学组成、施用时间以及有意分配,来探讨影响氮释放的不同途径。最后阐述提高氮利用率需要实施的农场外的(off-farm)的选择,尤其是对氮过剩的农业体系。 | Sigrun Dahlin Holger kirchmann Thomas Ktterer Sophie Gunnarsson Lars Bergstrm 张秋英 | 2005 | AMBIO-人类环境杂志2005，34，4： | 0 |
