数字地震台操作分析工具一DIMAS软件包简介

ＤＩＭＡＳ（Ｄｉｓｐｌａｙ，　Ｉｎｔｅｒａｃｔｉｖｅ　 Ｍａｎｉｐｕｌａｔｉｏｎ　ａｎｄ　Ａｎａｌｙｓｉｓ ｏｆ Ｓｅｉｓｍｏｇｒａｍｓ－“地震图 的显示和交互式操作与分析”）软件包是ｉｒｉｓ ＧＳＮ 台站所使用的数字地震分析应用软件． 同时它也适合我国部分数字台站（如ＮＣＤＳＮ）的日常分析工作，如波形放大与缩小、震相 拾取、震级计算、方位角计算、计算震中和震源深度以及发震时刻等；还可以做一些进一 步的分析处理工作，如波谱分析、滤波、分量旋转、质点运动分析以及仿真模拟地震图． 由于它是交互式菜单操作，所以有用户界面良好，易学易用，适合台站操作人员使用的特 点

TOOLS OF INTERACTIVE MANIPULATION AND ANALYSIS IN DIGITAL SEISMIC STATION -DIMAS SOFTWARE PACKAGE'S

DIMAS (Display, Interactive Manipulation and Analysis of Seismograms) software package is for the analysis of seismic digital data gained in iris GSN stations. It is also applied to daily data waveform amplification and reduction, shock-phase collection, magnitude calculation, azimuths angle calculation, epicenter calculation, depth of seismic focus, earthquake time analysis in some digital stations such as NCDSN of our country. Furthermore, some works as spectrum analysis, wave filtering, component revolving, particle movement analysis and simulatsed seismograms can be dealed with by using tile package. Because of its interactive menu manipulation feature, the package is very easy to operate.
