| 摘 要： | 为了使对地震前兆信息的分析过程更加方便,使用JavaScript语言编制地震曲线图网页,所有网页均由C#程序自动生成,程序连接数据库,每30分钟自动搜索数据更新情况,实时对数据进行更新、绘图.网页包含了所有台站的前兆数据,并且将数据进行分类,在单击台站分布图上的台站热点时,该台站的近期前兆观测曲线图将以网页形式展现出来.同时,每个台站的各个观测分量值也以列表形式排列在台站分布图的下方,其中包含了该分量最近1天、2天、1周、2周、1月的观测曲线,以及近一个月的观测数据的下载.当用户鼠标置于曲线图的任意点上时,可显示出该点对应的坐标值.并且所有曲线图网页均可以保存到本地使用.

| Abstract: | To make the analysis of seismic precursory information more convenient,this article uses the JavaScript language to create seismic graph page,all pages are generated by the C# program automatically.For the program connecting to the database,it checks data updating every 30 minutes automatically,updating and drawing in real-time.The page contains precursor data at all stations,and they are classified.When you click the hot spot of a station on the distribution of stations,the recent precursor observation curve will be shown in the form of a web page.Meanwhile,the value of each observation component of each station is arranged in tabular form below the station distribution map,which contains the observation curves of the last one day,two days,one week,two weeks,a month and observation data downloading of the last month.When the user puts the mouse on any point in the graph,the corresponding coordinate values of this point will display on the screen and all curves pages can be saved to local use. |
