目前,Windows NT Server 4.0中文版在网络市场比较流行,不少单位把它作为局域网最佳的网络操作系统,工作站大多选用Windows 95和Windows 98,各单位也利用Internet/intranet技术开发各类应用服务系统.建立了WEB主控服务器、电子邮件服务器、FTP服务器等,提供网上浏览各类信息及资源的共享.对于局域网管理员来说,对本地局域网终端上网网络参数配置都很熟悉,但在实践中,由于网络终端距本地网有相当一段距离而不能联接,就束手无策.这时,应考虑使用Windows NT Server 4.0提供的远程访问服务(RAS)功能. 相似文献

MM5模式是国际上应用比较广泛的一种中尺度气象模式，因为它采用了非静力平衡动力框架、可选择的多种物理过程以及四维同化(FDDA)等先进技术，在气象科研和业务预报领域取得了广泛的应用。由于技术的原因，MM5模式一直运行在UNIX系统之下，直接在Windows系统下运行的个例还不多。作者尝试将MM5模式由UNIX系统移植到Windows系统并据此建立了微机业务应用系统。详细介绍了模式在移植过程中所要注意的几个问题、微机业务技术系统的结构及预报方案。 相似文献

Urban areas are faced with mounting demands for managing waste and stormwater for a cleaner environment. Rainfall information is a critical component in efficient management of urban drainage systems. A major water quality impact affecting receiving waterbodies is the discharge of untreated waste and stormwater during precipitation, termed wet weather flow. Elimination or reduction of wet weather flow in metropolitan sewer districts is a major goal of environmental protection agencies and often requires considerable capital improvements. Design of these improvements requires accurate rainfall data in conjunction with monitored wastewater flow data. Characterizing the hydrologic/hydraulic performance of the sewer using distant rain gauges can cause oversizing and wasted expenditures. Advanced technology has improved our ability to measure accurately rainfall over large areas. Weather radar, when combined with rain gauge measurements, provides detailed information concerning rainfall intensities over specific watersheds. Knowing how much rain fell over contributing areas during specific periods aids in characterizing inflow and infiltration to sanitary and combined sewers, calibration of sewer system models, and in operation of predictive real-time control measures. Described herein is the design of a system for managing rainfall information for sewer system management, along with statistical analysis of 60 events from a large metropolitan sewer district. Analysis of the lower quartile rainfall events indicates that the expected average difference is 25.61%. Upper quartile rainfall events have an expected average difference of 17.25%. Rain gauge and radar accumulations are compared and evaluated in relation to specific needs of an urban application. Overall, the events analyzed agree to within ± 8% based on the median average difference between gauge and radar. 相似文献

Two important areas of Roshydromet activity are considered: the development of the space observation system and the creation of the system of ground-, air-, and space-based geophysical monitoring. The investigation, monitoring, and forecasting of the state of the Earth, its climate, severe weather events, catastrophes, and emergencies requires the extended usage of space observation methods. The current state is considered of hydrometeorological space system included in the Roshydromet space observation system. The space- and ground-based segments of this system are briefly described. The ground segment is based on the national space monitoring system which was developed in 1992—2010 and is geographically distributed. The works are reviewed on the formation of the Roshydromet geophysical monitoring system using ground-based, airborne, and space-based observations. 相似文献

Mapping global land system archetypes 总被引：1，自引：0，他引：1

Land use is a key driver of global environmental change. Unless major shifts in consumptive behaviours occur, land-based production will have to increase drastically to meet future demands for food and other commodities. One approach to better understand the drivers and impacts of agricultural intensification is the identification of global, archetypical patterns of land systems. Current approaches focus on broad-scale representations of dominant land cover with limited consideration of land-use intensity. In this study, we derived a new global representation of land systems based on more than 30 high-resolution datasets on land-use intensity, environmental conditions and socioeconomic indicators. Using a self-organizing map algorithm, we identified and mapped twelve archetypes of land systems for the year 2005. Our analysis reveals similarities in land systems across the globe but the diverse pattern at sub-national scales implies that there are no ‘one-size-fits-all’ solutions to sustainable land management. Our results help to identify generic patterns of land pressures and environmental threats and provide means to target regionalized strategies to cope with the challenges of global change. Mapping global archetypes of land systems represents a first step towards better understanding the global patterns of human–environment interactions and the environmental and social outcomes of land system dynamics. 相似文献
