乌溪矿区介于长江中下游多金属成矿带与华南成矿带之间,是江南造山带上的一个找矿新区.本文在这一找矿新区开展了有效的电磁方法综合勘探,试图对该区深部成矿机制进行研究.我们收集了该区的地质地球化学资料,从地质地球化学资料中分析了区域成矿背景;我们还采集了区域出露的主要岩石类型,在实验室开展物性测定,在此基础上选择了三种电磁方法开展研究区的野外测量.通过地面高精度磁测、激发极化法和可控源音频大地电磁法(CSAMT)三种地球物理方法,开展了研究区的磁化率、极化率和电阻率的分布特征研究.深入分析了地质、地球化学和地球物理三种资料与成矿的关系,相互约束,探讨成矿模型、成矿机制和成矿的可能性,推测可能的矿体赋存位置和深度范围.在地球物理研究结果基础上,结合地质和地球化学背景资料,构建了研究区的成矿动力学模型,推测了研究区成矿机制,揭示了矿区的成矿潜力.综合所得结果布设了钻孔,钻探结果揭示了研究区深部存在强烈矿化蚀变和强蚀变斑岩,初步确认为斑岩型矿床,与CSAMT剖面的解释结果基本一致,也与推测的测区内深部成矿机制相吻合.钻孔结果和地球物理结果的一致性以及对已构建的成矿动力学模型的支持,充分证明了综合电磁方法在斑岩型多金属矿床的发现和预测中的重要作用,同时斑岩型矿床的确认进一步印证了华南成矿带与俯冲作用形成的成矿带的相似性,从而推动整个华南地区的成矿地质研究.

为了获得某些材料在在高压条件下的物态方程,制备了用于激光驱动状态方程实验的铁铝阻抗匹配靶,研究了铁铝薄膜的精密热扩散连接技术。以冷轧铁薄膜和超精密加工铝薄膜为原料,研究了热复合工艺条件对其表面形貌、结晶性能、连接界面等参数的影响。利用白光干涉共焦显微镜、X射线衍射仪、膜厚测量仪、扫描电镜等仪器对靶件的表面形貌、厚度、结晶特性、残余应力及界面成分分布等进行分析表征,掌握了相关参数的变化趋势。据此优化工艺参数,制备了高质量的铁-铝阻抗匹配靶。对成靶的测试结果显示,其表面粗糙度小于100nm、厚度一致性控制在100nm以内、界面扩散层厚度约为200nm,且未观测到显微缺陷,满足物理实验的具体要求。

Novel Polymer Resistive-type Humidity Sensitive Materials

第四届全国RNA进展研讨会

作者： li jie, yang Guang, li Shaohua, Zhao Qiang, Ding Hongmei, Shen Beifen ,Shao Ningsheng Beijing Institute of Basic Medical Sciences, Beijing

RNA interference (RNAi)has been a powerful tool in genetic research, but there are many factors influencing siRNAs’s silencing effect including target site accessibility. Here, we found the siRNA-polyA molecules can introduce non-specfic silencing effect to exogenous gene when we used EGFP and RFP as reporter. At the same time, our experiment showed the non-specific effect strengthened alone with the growth of the polyA tail. But more interestingly, when we used ss-polyA as a control, we surprisingly found that ss-polyA with its length to 60nt or more longer could
