江淮流域夏季严重旱涝与大气季节内振荡

利用NCEP/NCAR的再分析资料和中国气象局国家气象中心提供的中国台站降水资料,分析研究了江淮流域大范围严重旱涝的20-70天大气季节内振荡(ISO)特征。结果表明,对应江淮流域严重涝年,200hPa青藏高原北部存在ISO气旋性环流,青藏高原南部存在ISO反气旋性环流;大气ISO流型在对流层中低层850hPa主要是我国长江以南、南海和西太平洋地区为大气ISO反气旋性环流,我国长江以北到日本地区的大气ISO气旋性环流,我国江淮流域位于这两个ISO涡旋西侧偏南气流和偏北气流的交汇处;旱年反之。利用向量经验正交展开方法得到,上述大气ISO环流型分别是旱涝年大气ISO流型的第一模态,并且涝年大气ISO流型的振幅强,旱年振幅弱。进一步分析揭示,严重洪涝(干旱)年分别对应对流层中上层江淮流域及其以北的中高纬度地区有强(弱)的大气ISO活动。中高纬度地区的大气ISO在严重洪涝年向南传播,与低纬度向北传播的大气ISO在江淮流域汇合;而在严重干旱年,虽然大气ISO可向北传播,但向南的传播却很不明显。

Foundations of petroleum prediction based on the activation of geochemical processes by direct current

Petroleum prediction in local objects and the applicability of geologic environment parameters in this regard are considered. The proposed guidelines for petroleum potential prediction are based on the analysis of the distribution of typomorphic epigenetic multivalent elements loosely fixed in rocks before and after electric current treatment. The advantage of geoelectrochemical methods providing data on the chemical composition of above-productive deposits is demonstrated.

A method for checking the quality of geographic metadata based on ISO 19157

With recent advances in remote sensing, location-based services and other related technologies, the production of geospatial information has exponentially increased in the last decades. Furthermore, to facilitate discovery and efficient access to such information, spatial data infrastructures were promoted and standardized, with a consideration that metadata are essential to describing data and services. Standardization bodies such as the International Organization for Standardization have defined well-known metadata models such as ISO 19115. However, current metadata assets exhibit heterogeneous quality levels because they are created by different producers with different perspectives. To address quality-related concerns, several initiatives attempted to define a common framework and test the suitability of metadata through automatic controls. Nevertheless, these controls are focused on interoperability by testing the format of metadata and a set of controlled elements. In this paper, we propose a methodology of testing the quality of metadata by considering aspects other than interoperability. The proposal adapts ISO 19157 to the metadata case and has been applied to a corpus of the Spanish Spatial Data Infrastructure. The results demonstrate that our quality check helps determine different types of errors for all metadata elements and can be almost completely automated to enhance the significance of metadata.     

半参数估计与LS估计的有效性比较

建立半参数回归模型,将系统误差加入,推导出了模型正则化矩阵时参数平差的计算方法,并用直接法得到了参数、非参数的估计量,在MSE准则下与最小二乘估值(简称LS估值)进行比较,证明了半参数估值的有效性。     

测绘行业贯彻ISO9000族标准的若干思考

随着社会主义市场经济的日益完善和管理科学的不断发展，产品质量越来越引起各行各业的高度重视。为了促进测绘行业质量管理的科学化，程序化和标准化，逐步实现管理模式与国际接轨，提高测绘质量管理水平，增强市场竞争能力，在绘行业推行ISO9000族标准已势在必行。文中简要介绍了ISO9000族标准的基本概念，阐述了贯彻认证的意义，方法及步骤等。     

International Association of Geoanalysts' Protocol for the Certification of Geological and Environmental Reference Materials: A Supplement

The International Association of Geoanalysts (IAG) published a protocol for the certification of reference materials in close accord with the International Organisation for Standardisation (ISO) guidelines (Kane et al. 2003). This article supplements that protocol, providing additional discussion of best approaches for pre-selecting laboratories for participation in certification projects. This discussion also makes a distinction between inter-laboratory certifications, where n = 15 is the general standard, and expert laboratory certifications, where a much smaller number of laboratories will be deemed qualified to provide data of the quality needed for certification.
