福建上杭铜矿沟—萝卜岭斑岩型铜矿床地质特征及远景评价

上杭县铜矿沟和萝卜岭矿段组成一个斑岩型铜矿床．萝卜岭矿段位于花岗闪长斑岩北东端的前峰部位，铜矿沟则是其往南西深部的延伸，通过对铜矿沟—箩卜岭斑岩型铜矿床地质特征的研究，认为铜矿沟斑岩型铜矿埋藏总体较浅、品位较低、厚度稳定且较厚，对于指导该区寻找浅部斑岩型铜矿具有重要的意义。     

零价铁去除Cr（Ⅵ）的批实验研究

零价铁去除Cr(Ⅵ)的一系列批实验结果表明：水溶液中发生的氧化还原反应符合准一级反应；对于相同粒度的铁屑(比表面积2．89m^2／g)，固液比由05g／100mL增加到2．0g／100mL，Cr(Ⅵ)质量浓度达到排放标准所需反应时间从26．7min降为3．6min；在固液比相同、原水中Cr(Ⅵ)质量浓度不超过30mg／L时，原水质量浓度增大，达到饮用水标准的反应时间增加；其他条件相同，升高温度可提高零价铁与Cr(Ⅵ)的反应速率。     

科技期刊编辑应具备的基本素质

对科技期刊质量和编辑素质的关系进行了研究，认为编辑是期刊的设计师。一本期刊从总体创意、策划选题、编审稿件到排版设计，无不体现编辑的主体意识。期刊质量的好坏，读者评价的高低都与编辑息息相关。编辑的素质关系到期刊的生存和发展。得出不断提高科技期刊编辑的素质是十分必要的结论。     

上海及邻区的地壳形变速率与地震活动

对上海佘山地震台伸缩仪的数字记录资料进行去趋势以及地壳形变速率的分析表明：伸缩仪EW向在200l年5～7月存在破年变趋势异常，并且该测项的形变速率在2001年3～8月存在高于正常背景值的异常。结合GPS资料、应力场、地震活动性的情况分析后认为，佘山台的形变速率异常可反映上海及邻区应力场的部分信息，该信息对地震活动具有一定前兆意义。因此，应用形变数字化资料计算地壳形变速率，可作为对地层活动以及日常地震预测的一种分析方法。     

睡莲类植物ITS nrDNA序列的分子系统发育分析

睡莲类植物是目前植物分子系统学与进化研究的一个重要类群。核基因组的ITS区是核核糖体（nrDNA)转录单位的一部分。测定和分析了5个属的7种睡莲类植物的核核糖体ITS序列，并与GenBank中提取的相关序列进行了组合分析，初步获得了睡莲类植物的2个ITS系统树，结果也支持现有分子系统学研究中有关金鱼藻处于较原始位置的观点。     

Scaling effects on modeled surface energy-balance components using the NOAH-OSU land surface model

As surface exchange processes are highly non-linear and heterogeneous in space and time, it is important to know the appropriate scale for the reasonable prediction of these exchange processes. For example, the explicit representation of surface variability has been vital in predicting mesoscale weather events such as late-afternoon thunderstorms initiated by latent heat exchanges in mid-latitude regions of the continental United States. This study was undertaken to examine the effects of different spatial scales of input data on modeled fluxes, so as to better understand the resolution needed for accurate modeling. A statistical procedure was followed to select two cells from the Southern Great Plains 1997 hydrology experiment region, each 20 km×20 km, representing the most homogeneous and the most heterogeneous surface conditions (based on soil and vegetation) within the study region. The NOAH-OSU (Oregon State University) Land Surface Model (LSM) was employed to estimate surface energy fluxes. Three scales of study (200 m, 2 and 20 km) were considered in order to investigate the impacts of the aggregation of input data, especially soil and vegetation inputs, on the model output. Model results of net radiation and latent, sensible and ground heat fluxes were compared for the three scales. For the heterogeneous area, the model output at the 20-km resolution showed some differences when compared with the 200-m and 2-km resolutions. This was more pronounced in latent heat (12% decrease), sensible heat (22% increase), and ground heat flux (44% increase) estimation than in net radiation. The scaling effects were much less for the relatively homogeneous land area with 5% increase in sensible heat and 4% decrease in ground heat flux estimation. All of the model outputs for the 2- and 20-km resolutions were in close agreement. The results suggested that, for this study region, soils and vegetation input resolution of about 2 km should be chosen for realistic modeling of surface exchange processes. This resolution was sufficient to capture the effects of sub-grid scale heterogeneity, while avoiding the data and computational difficulties associated with higher spatial resolutions.
