After the field survey, the technique and implementation group of igcsb chose dajianshan where is 18km away from lanzhou seismic station in the south - west as the array site among several backup sites, and enforced a site survey on august, 1999. eignt suits of instruments supported by the analysis and prediction center, csb were used for the field observation, and 18 sites were deployed on two concentric circles and a beeline respectively. during the 18 days, we achieved about 3gb waveform data
1999年8月,中國地震局地球物理研究所臺陣建設技術實施組經過實地考察,從幾個候選陣址中選中蘭州地震臺西南方向18km的大尖山作為ims蘭州臺陣陣址,在中國地震局分析預報中心的支持下,投入了8套地震儀器以同心圓分佈和直線分佈方式在蘭州大尖山陣址對18個測點進行了為期18天的野外觀測,取得了約3gb的地震數據。Topographical maps are the principal frame form of gis, and realization map digitizing and offering gis basic spatial data is one of the important research fields in surveying and gis, which is also necessity of development of science and technology. based on building gis - oriented topographical mapping system theories, this themes apply the advanced objectarx technology, aim at topographical mapping and exporting to gis, and resolve several key problems, such as symbols analysis and building, dtm and contour line automatic drawing, topographical map adjoining, digital image rectifying etc. and it offers models and arithmetic, realizing the general functions of gis - oriented topographical mapping system
本文以建設面向gis的測量繪圖平臺理論為基礎,以autocad平臺下objectarx開發技術為核心,圍繞地形圖的成圖和入庫( gis數據庫)這一課題,對其中的關鍵技術難題? ?符號庫的建立與實現、 dtm與等高線的自動繪制、地形圖接邊、數字化柵格圖像的定向與糾正、介面數據文件的生成等進行了研究分析,提出了相應的模型和演算法,實現了面向gis的測量繪圖系統的基本功能。The evolution and development of the mobile network bring new issues to the network optimization. and it makes network optimization involve more complex techniques and multiple fields. for all of the above reasons, it is necessary to develop a platform to analyse pilot data, geographic information system ( gis ) data and operation & maintenance center ( omc ) data synthetically
移動網路的演進和發展為網路優化不斷帶來新的課題,使網路優化的工作難度更大,涉及到更多的領域,因此實現一種能夠將路測數據、 gis ( geographicinformationsystem地理信息系統)數據和omc ( operationandmaintenancecenter操作維護中心)數據進行綜合分析的平臺,是網路優化技術發展的方向。Commencing today, for those tropical cyclones centred within the region bounded by 7 - 36 degrees north and 100 - 140 degrees east area shaded in light green in the figure, their positions at 8 a. m. and 8 p. m. and 72 - hour forecast tracks will be made available on the observatory s website at around noon and midnight respectively
為了更早向市民提供熱帶氣旋的資料,從今天開始,當熱帶氣旋中心位於北緯7至36度,東經100至140度以內圖中淺綠色范圍,天文臺會在每天約中午及午夜在網上發放該熱帶氣旋分別在上午八時及晚上八時的觀測位置及72小時的預測路徑圖。In case of a loss or impending loss of all or a portion of the electric supply from a power source outside hong kong, electrical and mechanical services department and the hko will be alerted by the clp system control centre at tai po according to an established notification system for power interruptions
如失去或即將失去香港境外電源的全部或部分供電時,中電在大埔的監測系統控制中心會按照既定的電力中斷通報機制,通知機電工程署及香港天文臺。有關廣東核電站核事故的情況,港方亦可向港核投深入了解。分享友人
