精确厘定金属矿床的成矿时代对揭示成矿动力学背景,探讨成矿物质、成矿流体来源和建立切合实际的矿床成因模式具有重要意义。矿石矿物或金属矿物的Re-Os同位素体系是金属矿床直接定年和示踪的重要手段,辉钼矿含有较高的Re含量(ppm级别)且基本不含普通Os, 是最理想的定年对象。目前常用的辉钼矿Re-Os同位素分析方法是卡洛斯管密闭酸溶法,该方法具有空白低的优点,但流程相对复杂且卡洛斯管有发生爆炸的危险,需要专业人士操作,同时分析成本较高。

随着交流电力机车的广泛使用,牵引网负序和过分相问题日益突出,采用配置铁路功率调节器（railway power conditioner,RPC）的同相供电系统是一种可行方案.为了提高该方案中功率调节系统的性价比,本文提出了一种适用于同相供电系统的新型混合铁路功率调节器（hybrid RPC,HRPC）.与传统RPC相比,该系统变流器的端口电压更低,从而大幅降低了有源部分的容量.文章详细描述了系统的拓扑结构、补偿原理,给出了关键参数的设计方法,并对HRPC的容量进行了系统分析.研究结果表明,在完成相同补偿任务的前提下,所提HRPC变流系统的容量将比传统RPC降低46%-50%.所得结论通过仿真得到了验证.

作者： Liu W, hu j. Y. Beijing Astronomical Observatory, National Astronomical Observatories, The Chinese Academy of Sciences, Beijing 100012, China Email: liuwu@class1. bao. ac. cn

We present time resolved optical light curves in R bands obtained from differential photometry on sequential CCD frams of 4 new discovered high galactic latitude CVs, which are discovered by our spectroscopic observations of the optical identification of ROSAT X ray sources. The analysis of the light curves shows repeatable periodicity in these objects. j020348 7+295921 exhibits 0 5m variation with orbital period of 258 min. j062518 2+733433 reveals a 0 3 mag modulation with orbital period of 254min. j230949 6+213523 shows probably both orbital period of 207 min and WD spin period of 25 min. j232953 9+062814 present short period of 32min, indicating a magnetic system.
