1Environmental magnetic studies of lacustrine sediments显示文摘In recent decades, environmental magnetism has become an important method for studying past global climatic and environmental changes. For an environmental magnetic study, it is important to understand the magnetic properties of various magnetic minerals in lacustrine sediments and the processes involved in the formation, transport, and preservation of these magnetic minerals. The magnetic response of lacustrine sediments to climatic change may vary widely from lake to lake. To reconstruct the processes contributing to paleoclimatic and paleoenvironmental change, it is, therefore, necessary to derive a complete understanding of the potential origin of the magnetic signal observed.HU Shouyun, DENG Chenglong, E.

7Garnet Sm-Nd and U-Pb systems: A case study of a granulite from the European Variscan belt显示文摘This study presents zircon and garnet ages of a mafic granulite from the high-grade Variscan basement of the Black Forest, Germany and discuss isotope closure temperature of garnet Sm-Nd and U-Pb systems. Zircon grains yield 207Pb/206Pb ages between -340 and -414 Ma by the U-Pb and evaporation methods. In contract, garnet dating gives Sm-Nd and Pb-Pb isochron ages of (398±3) Ma and (411±14) Ma, respectively, which are older than most of zircon ages. These data imply that most of zircons lost radiogenic Pb, probably due to metamictization or recrystallisa-tion during the granulite-facies metamorphism (-800°C) at -340 Ma. Garnet Sm-Nd and U-Pb systems preserve chronological information of pro-grade metamorphism, probably profiting from a fluid-absence metamorphic environment. These results demonstrate that garnet mineral can be a better candidate than zircon mineral to date high-grade metamorphism by the U-Pb and Sm-Nd methods in some cases.CHEN FukunInstitut fur Mineralogie, Petrologie und Geochemie, Universitat Tubingen, 72074 Tubingen, Germany Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing 100029, China 2002Chinese Science Bulletin2002,47,15:1
8髓外造血影像学表现显示文摘髓外造血是一种多能干细胞异常增殖生成血细胞方式,可生成红细胞、白细胞和淋巴细胞。在胚胎发育期,造血在卵黄囊上进行,称之为中胚叶造血期。随后造血在肝脏和脾脏进行(肝脏造血),大约从第7个月开始骨髓开始产生血细胞(骨髓造血)。Teufel M Bares R Ernemann U Horger M Tubingen 曹毅媛(译) 胡道予(校) 2010放射学实践2010,25,G00:0
9假膜性结肠炎的CT诊断显示文摘假膜性结肠炎(pseudo—membranous colitis,PMC)是一种有可能危及生命的急性感染性结肠炎,肠管内的艰难梭状芽孢杆菌数量无限制增多的前提下由一种或多种分泌毒素致病。假膜性肠炎特征性的表现是在结肠黏膜上形成黄白色的假膜斑块。CT对于假膜性肠炎的评估很有帮助。Schulze M Fritz J Joanoviciu SD Horger M Tubingen 曹毅媛(译) 胡道予(校) 2010放射学实践2010,25,G00:0
