【摘要】 使用MATLAB实现了一种简便对地震视应变的计算方法。先由该软件从地震目录找出所要研究区域中符合震级、经纬度范围的地震目录,从而根据地震视应变计算公式计算出每个符合要求的地震所对应的视应变,之后对该区的地震视应变以3年为窗口、1年与1平方度为时空步长,逐步滑动,便可以研究地震视应变场的时空动态演化。此软件具有简便、快速、实用的优点。更多还原

【Abstract】 We use MATLAB to realize a simple calculating method of seismic apparent train.First pick out the seismic catalog of the researched region from the entire catalog, which conforms to the requirements for magnitude,latitude,and longitude.Then We cal- culate the apparent strain for each qualified event according to calculating formula.Taking a 3-year sliding window with one year and one square degree as the temporal and spacial step length,we can study the characteristic of space-time evolution of seismic apparent strain.This software is simple,fast,and practical.更多还原
