| 1 | 气候变化对中国农业气候资源的影响显示文摘气候变化将对我国的农业气候资源产生重要影响,评估其潜在影响可为制定未来农业区域发展和应对气候变化策略提供科学依据。本研究基于区域气候模式PRECIS在IPCC SRES A2和B2情景下21世纪末期(2071年-2100年)的气候预估数据,利用农业生态地带模型AEZ(Argo-ecological Zones)模拟气候变化对我国农业气候资源的可能影响。结果表明,在两种气候变化情景下,我国稳定≥10℃积温所反映的热量条件显著改善,由积温所反映出的种植制度也发生明显变化,各种植带界限明显北移。由于气温的升高,导致参考作物蒸散普遍增加。降水的增加使得西北地区干旱状况有所改善,生长期延长。我国东南部的中、南亚热带地区则由于降水过多而使得生长期有所缩短。 | 汤绪 杨续超 田展 Gnter Fischer 潘婕 | 2011 | 资源科学2011,33,10: | 59 |

| 3 | Management of early gastrointestinal neuroendocrine neoplasms显示文摘Neuroendocrine neoplasms (NENs) of the stomach, duo- denum, appendix or rectum that are small (≤ 1 cm) and well differentiated can be considered 'early' tumors, since they generally have a (very) good prognosis. In the new WHO classification of 2010, these neoplasms are called neuroendocrine tumors/ carcinoids (NETs), grade (G) 1 or 2, and distinguished from poorly differentiated neuroendocrine carcinomas (NECs), G3. NETs are increasing, with a rise in the age-adjusted incidence in the U.S.A. by about 700 % in the last 35 years. Improved early detection seems to be the main reason for these epidemiological changes. Both the better generalavailability of endoscopy, and imaging techniques, have led to a shift in the discovery of smaller-sized (≤ 10-20 mm) intestinal NETs/carcinoids and earlier tumor stages at diagnosis. Endoscopic screening is therefore effective in the early diagnosis, not only of colorectal adenocarcinomas, but also of NETs/carcinoids. Endoscopic removal, followed up with endoscopic surveillance is the treatment of choice in NETs/carcinoids of the stomach, duodenum and rectum that are ≤ 10 mm in size, have a low proliferative activity (G1), do not infiltrate the muscular layer and show no angioinvasion. In all the other intestinal NENs, optimal treatment generally needs surgery and/or medical therapy depending on type, biology and stage of the tumor, as well as the individual situation of the patient. | Hans Scherübl Robert T Jensen Guillaume Cadiot Ulrich Stlzel Günter Klppel | 2011 | World Journal of Gastrointestinal Endoscopy2011,3,7: | 13 |
| 4 | Neuroendocrine tumors of the small bowels are on the rise:Early aspects and management显示文摘Neuroendocrine tumors of the small bowel are on the rise. In the US they have increased by 300%-500% in the last 35 years. At the same time their prognosis is much improved. Today,most neuroendocrine tumors (NETs) of the duodenum are detected 'incidentally' and therefore recognized at an early stage. Duodenal NETs which are well differentiated,not larger than 10 mm and limited to the mucosa/submucosa can be endoscopically resected. The management of duodenal NETs ranging between 10 and 20 mm needs an interdisciplinary discussion. Endoscopic ultrasound is the method of choice to determine tumor size and depth of infiltration. Surgery is recommended for well-differentiated duodenal NET tumors greater than 20 mm,for localized sporadic gastrinomas (of any size) and for localized poorly differentiated NE cancers. Surgery is recommended for any ileal NET. Advanced ileal NETs with a carcinoid syndrome are treated with longacting somatostatin analogs. This treatment significantly improves (progression-free) survival in patients with metastatic NETs of the ileum. For optimal NET management,tumor biology,type,localization and stage of the neoplasm,as well as the patient's individual circumstances have to be taken into account. | Hans Scherbl Robert T Jensen Guillaume Cadiot Ulrich Stlzel Gnter Klppel | 2010 | World Journal of Gastrointestinal Endoscopy2010,2,10: | 10 |
| 5 | 煤粉燃烧中NO_x和SO_x生成的详细反应机理模拟显示文摘采用详细化学反应机理与CFD方法耦合的煤粉燃烧数值模拟程序,计算了煤粉燃烧过程中CO,NO_x和SO_x等的浓度分布特性.通过与实验对照,验证了数值模拟方法的可靠性,并分析了燃烧温度和煤粉细度等因素对于NO生成的影响.结果表明温度对于NO的生成影响较大,随着温度的增加,NO的生成浓度明显增加;对于不同煤种,可能存在一个温度点,这时NO的生成速率将非常快;在计算范围内,温度对SO_2的最终生成浓度没有明显影响,而只影响SO_2的释放过程.煤粉细度对于NO生成有较小的影响. | 魏小林 韩小海 Uwe Schnell Günter Scheffknecht Benedetto Risio | 2008 | 力学学报2008,40,6: | 8 |
| 6 | 采用计量型扫描力显微镜校准微纳米标准样板显示文摘为了建立质量保证体系,微米和纳米样板至今仍被广泛地应用于校准微纳米尺度的测量仪器中.介绍了应用由德国联邦物理研究所开发研究的、测量范围为25 mm×25 mm×5 mm的计量型扫描力显微镜(M-LRSFM)的校准方法.上述计量型扫描力显微镜配置有三个零拍的激光干涉仪,可分别测量沿x、y、z三条轴线方向的位移,因而其测量值可直接溯源于“米”定义.此种M-LRSFM能够校准横向的微纳尺度的结构尺寸,诸如阶梯高度、一维和二维光栅、镀层厚度、线宽、微纳尺度的表面粗糙度等.作为实例,介绍了一种横向样板的校准程序及获得的校准结果.研究表明这种方法适合于校验扫描电子显微镜(SEM)的放大倍率. | 戴高良 KOENDERS Ludger DANZEBRINK Ulrich WILKENING Günter 周健雄 陈振宇 | 2006 | 纳米技术与精密工程2006,4,1: | 8 |

| 8 | Sporadic versus hereditary gastrinomas of the duodenum and pancreas: Distinct clinico-pathological and epidemiological features显示文摘Gastrinomas are defined as gastrin secreting tumors that are associated with Zollinger-Ellison syndrome (ZES). ZES is characterized by elevated fasting gastrin serum levels, positive secretin stimulation test and clinical symptoms such as recurrent peptic ulcer disease, gastroesophageal re?ux disease and occasional diarrhea. Genetically, nonhereditary (sporadic) gastrinomas are distinguished from hereditary gastrinomas, which are associated with multiple endocrine neoplasia type 1 (MEN1) syndrome. In general, duodenal gastrinomas are small and solitary if they are sporadic and multiple as well as hereditary. The sporadic gastrinomas occur in the duodenum or in the pancreas while the hereditary gastrinomas almost all occur in the duodenum. Our series of 77 sporadic duodenal neuroendocrine tumors (NETs) includes 18 patients (23.4%) with gastrinomas and ZES. Of 535 sporadic NETs in the pancreas collected from the NET archives of the departments of pathology in Zürich, Switzerland, and Kiel, Germany, 24 patients (4.5%) suffered from sporadic pancreatic gastrinomas and ZES. These NETs have to be distinguished fromtumors with immunohistochemical positivity for gastrin but without evidence of ZES. An additional 19 patients suffered from MEN1 and ZES. These patients showed exclusively duodenal gastrinomas, but not pancreatic gastrinomas. The prognosis of sporadic and MEN1- associated duodenal gastrinomas is better than that of pancreatic gastrinomas, since they progress slowly to liver metastasis. In summary, sporadic and MEN1- associated gastrinomas in the duodenum and pancreas show different clinico-pathological and genetic features. The incidence of sporadic duodenal gastrin-producing tumors is increasing, possibly due to optimized diagnostic procedures. In contrast, pancreatic MEN1- associated gastrinomas seem to be extremely rare. A considerable subset of tumors with immunohistochemical expression of gastrin but without evidence of ZES should be designated as functionally inactive NETs expressing gastrin, but not as gastrinomas. | Martin Anlauf Nele Garbrecht Tobias Henopp Anja Schmitt Regina Schlenger Andreas Raffel Markus Krausch Oliver Gimm Claus F Eisenberger Wolfram T Knoefel Henning Dralle Paul Komminoth Philipp U Heitz Aurel Perren Günter Klppel | 2006 | World Journal of Gastroenterology2006,12,34: | 7 |

| 10 | Pathology of pancreatic ductal adenocarcinoma:Facts,challenges and future developments显示文摘Despite major improvements concerning its diagnosis and treatment,pancreatic ductal adenocarcinoma(PDAC) remains an aggressive disease with an extremely poor prognosis. Pathology,as interface discipline between basic and clinical medicine,has substantially contributed to the recent developments and has laid the basis for further progress. The definition and classification of precursor lesions of PDAC and their molecular characterization is a fundamental step for the potential identification of biomarkers and the development of imaging methods for early detection. In addition,by integrating findings in humans with the knowledge acquired through the investigation of transgenic mouse models for PDAC,a new model for pancreatic carcinogenesis has been proposed and partially validated in individuals with genetic predisposition for PDAC. The introduction and validation of a standardized system for pathology reporting based on the axial slicing technique has shown that most pancreatic cancer resections are R1 resections and that this is due to inherent anatomical and biological properties of PDAC.This standardized assessment of prognostic relevant parameters represents the basis for the successful conduction of multicentric studies and for the interpretation of their results.Finally,recent studies have shown that distinct molecular subtypes of PDAC exist and are associated with different prognosis and therapy response.The prospective validation of these results and the integration of molecular analyses in a comprehensive pathology report in the context of individualised cancer therapy represent a major challenge for the future. | Irene Esposito Bj?rn Konukiewitz Anna Melissa Schlitter Günter Kl?ppel | 2014 | World Journal of Gastroenterology2014,20,38: | 5 |

| 12 | 气候变化和紫外线辐射对北极淡水鱼类及溯河产卵鱼类渔业的影响显示文摘北极淡水鱼类和洄游鱼类渔业为北方经济做出了重大贡献。但是,对于淡水水体,气候变化和增长的紫外线辐射对渔业产生的巨大影响有3个方面:可获鱼的数量、质量和捕捞成功率。因此,在这些影响发生作用之际,可能需要实质有效的适应行为以引导北极未来的渔业走向可持续性。当务之急是为商业渔业选择灵活和快速反应的'适宜管理'方式;改变生计渔业的当地土地和资源利用模式;改变很多休闲渔业的特性、管理方式和地点。总的来说,在气候变化及其对北极淡水水域和生物区影响的复杂性和不确定性情况下,为保证生态系统和主导鱼种有足够的恢复力和应对将来变化的能力,需要对渔业的各个方面实施更保守的管理办法。 | James D.Reist Frederick J.Wrona Terry D.Prowse J.Brian Dempson Michael Power Günter Kck Theresa J.Carmichael Chantelle D.Sawatzky Hannu Lehtonen Ross F.Tallman 曾首英 | 2006 | AMBIO-人类环境杂志2006,35,7: | 4 |
| 13 | 高使用性能粉末冶金零件的表面致密化显示文摘为保证机构的可靠性,历史上一直在用锻钢合金批量生产高转矩变速器零件,诸如变速器齿轮、高性能链轮、单向离合器座圈及滚珠轴承座圈。虽然用粉末冶金工艺生产的零件成本低廉,但常规粉末冶金钢的静态、疲劳及耐磨性能的局限性,使粉末冶金零件不能应用于上述领域。为解决这些缺欠,近年来,一直在研发用选择性表面致密化(SSD)改进粉末冶金钢性能的各种生产工艺。特别是,PMG集团开发出了一种拥有专利权的表面致密化工艺——DensiForm。利用这种工艺可使零件表面关键部分形成深度达1mm的完全致密化表面层,而零件心部仍然是多孔性的。这种结合与粉末冶金材料合金化的灵活性,使生产的烧结钢零件的使用性能可与在高应力下使用的锻钢性能相比拟。本文将介绍2个例子,即变速器中应用的表面致密化螺旋齿轮和直齿链条的驱动链轮。本文说明了螺旋齿轮和驱动链轮的生产工艺与显微组织,介绍了轿车变速器用螺旋齿轮的性能(其中包括在三轴总成的成对试验台架上得到的滚动接触疲劳的数据)和表面致密化链轮的材料性能与使用性能。 | Lorenz S Sigl Günter Rau Christian Dennert | 2012 | 粉末冶金技术2012,30,2: | 4 |

| 15 | 表面致密化粉末冶金齿轮的性能显示文摘用压制、烧结及选择性横向辗压表面致密化制造了轿车变速器的粉末冶金螺旋齿轮。在生产的每一道工序中都根据显微组织、齿轮几何形状、表面粗糙度及DIN品质对齿轮的性能演变进行了监控。将粉末冶金齿轮的几何形状和现在变速器中使用的常规生产的锻钢齿轮(DIN品质7)进行了比较。表明,制造的粉末冶金齿轮的品质位于DIN品质8范围以内;而且,证明通过生产工序的改变可减小对中与齿廓的误差。虽然锻钢齿轮的对中与齿廓误差较小,但是粉末冶金齿轮的偏心率与节矩的误差和表面粗糙度较好。 | Lorenz S.Sigl Günter Rau Michael Krehl 韩凤麟(译) | 2012 | 粉末冶金技术2012,30,3: | 4 |

| 18 | Emerging pollutants in the environment:A challenge for water resource management显示文摘A significant number of emerging pollutants(EPs)resulting from point and diffuse pollution is present in the aquatic environment.These are chemicals that are not commonly monitored but have the potential to enter the environment and cause adverse ecological and human health effects.According to the NORMAN network,at least 700 substances categorized into 20 classes,have been identified in the European aquatic environment.In light of their potential impact action is urgently required.In this study,we present a concept that shows the current state of art and challenges for monitoring programs,fate and risk assessment tools and requirements for policies with respect to emerging pollutants as a base for sustainable water resource management.Currently,methods for sampling and analysis are not harmonized,being typically focused on certain EP classes.For a number of known highly hazardous EPs detection limits are too high to allow proper risk assessment.For other EPs such as microplastics method development is in its infancy.Advanced ultra-sensitive instrumental techniques should be used for quantitative determination of prioritized EPs in water,suspended matter,soil and biota.Data on EPs'and their metabolites'properties that determine their fate in the environment are often not available.National surveys on water quality often use different parameters for water quality assessment and often do not include EPs.A harmonized monitoring of surface and groundwater is not yet achieved and urgently required.Specific component integrated into models assessing the fate of EPs in a multi compartment environmental approach are missing and must be developed.The main goal of risk assessment is the overall protection of ecological communities in the aquatic environment and human health.New methods for assessing the cumulative risks from combined exposures to several stressors,including mixtures of EPs in a multi-scale approach are required.A combination of regulations and management measures with respect to use/emissions of EPs into the environment,as well as to their occurrence in the environment are fundamental to reach an efficient water resource management. | Violette Geissen Hans Mol Erwin Klumpp Günter Umlauf Marti Nadal Martine van der Ploeg Sjoerd E.A.T.M.van de Zee Coen J.Ritsema | 2015 | International Soil and Water Conservation Research2015,3,1: | 3 |
