长江中下游成矿带作为中国东部重要的成矿带之一,成矿地质条件、成矿规律和成矿模式的相关研究已经十分深入,形成了一系列公认的理论研究成果,本文重点论述了成矿带成矿地质条件和成矿规律方面研究的新进展,并在此基础上构筑了成矿带的成矿模式。本文主要开展了以下总结工作:(1)将成矿带的构造要素突破以往按构造单元分解的做法,确立跨构造单元的"复合构造系统",结合成矿带成岩成矿作用特点,重新确定了长江中下游成矿带的范围,并对成矿亚带进行了重新划分;(2)收集汇总了长江中下游成矿带近年来国内外学者最新的成岩成矿年龄数据,总结了矿床时空分布规律;(3)从地质,地球物理和地球化学等方面,总结归纳了沿基底结合带复活的网状断裂系统,阐明了成矿带的控矿构造格架,分析了长江中下游成矿带的成因规律;(4)补充和完善了断隆区和断凹区的成矿模式,并初步构筑了长江中下游成矿带综合成矿模式。提出长江中下游成矿带内主体成岩成矿作用总体上分为走滑挤压阶段(146~135Ma)、走滑引张阶段(135~126Ma)和拉张伸展阶段(126~123Ma)等三个阶段,古太平洋板块作用导致的壳幔过程,引发含元古代弧岩浆岩源区活化和中生代的构造活化("双活化")是长江中下游成矿带形成的主要机制。

针对1 400～2 800m主跨斜拉桥整体刚度不足的问题,提出一种新型结构方案——碳纤维增强塑料(cFRP)-钢组合拉索斜拉桥。该方案将cFRP斜拉索与传统钢斜拉索同时应用于斜拉桥中,组合2种材料高强轻质及弹性模量高的优点,以达到提高斜拉桥整体刚度的设计目的。通过基于力学与造价的参数分析提出该组合拉索斜拉桥的3种设计原则:等安全系数等效刚度最优、等安全系数等效刚度性价比最优、等造价等效刚度最优,并分别给出详细的设计步骤及设计用图。最后,进行了多种方案1 400m主跨斜拉桥试设计。结果表明:cFRP-钢组合拉索斜拉桥在力学与经济性方面均具有一定优势,其工程应用具有可行性,是主跨为1 400～2 800m斜拉桥的优选方案之一。

This paper discusses the spatial and seasonal distribution character of dissolved and paniculate trace metals in the anoxic seawater of Saanich Inlet, B.c., canada. The study showed that concentration of dissolved and paniculate trace metals in anoxic seawater is closely related to (1) the concentration of H2S and the depth of the O2-H2S interface, (2) the exchange of seawater in Saanich Inlet with outside seawater, (3) biotic action, and (4) the flushing event. The study was based in part on the ratio between trace metals and nutrients. There was a steep change in the concentration of dissolved trace metals at the O2-H2S interface. The concentration of dissolved trace metals in the H2S-controlled zone was dependent on the H2S there. The suspended matter in Saanich Inlet comes from the Hero Strait seawater, phytoplankton production and resuspension of flushed-up sediments. The concentration of particulate trace metals was rather low in Saanich Inlet and tended to increase with depth. The total
