1金厂沟梁-二道沟金矿田内花岗岩类侵入体锆石的离子探针U-Pb年代学及意义显示文摘金厂沟梁-二道沟金矿田内花岗岩类侵入体SHRIMP锆石U-Ph定年结果表明,该区中生代以来到少经历了三次中酸性岩浆侵入作用,它们分别以西台子二长花岗岩、娄上含辉石石英闪长岩和西对面沟花岗闪长岩及闪长玢岩脉在218±4Ma(印支期)、161±1Ma(燕山早期)和126±1Ma(燕山晚期)的侵位为标志。花岗岩类的地球化学资料表明,这些花岗岩类侵入体形成与造山作用有关,为造山后或陆内拉张作用的产物。二道沟矿区成矿前或成矿期闪长玢岩脉的年龄126±1Ma限定了该区金矿化的最大年龄;结合前人有关年代学资料,认为本区金矿化应发生在126~118Ma。这说明金厂沟梁-二道沟金矿田的金矿床与我国胶东、小秦岭和辽东等地区的金矿床是同时形成的,再次证明燕山晚期是中国最重要而广泛的金成矿期。此外,在这些主要的金矿区内,金矿化时间上均具有与各自区内最晚一次花岗质岩浆作用同时或稍晚的特征,这可能指示金矿床是造山作用或区域构造-岩浆演化最晚期的产物。苗来成 范蔚茗 翟明国 Qiu Y M McNaughton N J Groves D I 2003岩石学报2003,19,1:70
2Flexible organic light-emitting diodes with poly-3,4-ethylene-dioxythiophene as transparent anode显示文摘The flexible oragnic light-emitting diodes (OLEDs) fabricated on poly -3,4-ethylenedioxythiophene/poly -styrenesulfonate(PEDOT/PSS) coated substrates were demonstrated. How the fabricating processes and the device structure will affect the device performance was studied and the atomic force microscopy was employed to analyze the mophorlogy of the conducting polymer anode. Under optimized conditions, flexible OLEDs with PEDOT anode showed the brightness up to 2760 cd/m2 and maximum external quantum efficiency of 1.4%. These data are comparable to those of conventional flexible OLEDs with ITO anode.Qiu, Y Duan, L Wang, LD 2002Chinese Science Bulletin2002,47,23:4

8Durable Asphalt Pavements Are Self Healing显示文摘The traffic volume and the number of heavy vehicles are growing continuously. Considering the continuous traffic flow and the limited time available for road maintenance,it is very important to design a durable pavement system. Asphalt pavements with a healing capability are believed to be very useful since they can extend the pavement service life thanks to rest periods and hot summers. In order to design durable asphalt pavements,research in understanding and upgrading the self-healing capability of bituminous materials in time is of major importance. The self healing capability of bituminous mastic was evaluated in this research with a direct tension healing test. In the test program,different healing times,crack status and modifications were applied. The results indicate that elastic recovery and flow capacity are important factors for the self healing capability of bituminous materials at different crack phases as simulated with the direct tension test.QIU J VAN DE VEN M F C WU S P YU J Y MOLENAAR A A A 2010武汉理工大学学报2010,32,17:2
