叠前时间偏移代码，fortran格式，可以用于三维地震数据处理，可以在此基础上进一步完善其应用范伟。(Kirchhoff time migration code fortran version)

说明：  用于abaqus显式动力学分析的3D Hashin 损伤二次开发算法代码(3D Hashin damage redevelopment algorithm code for ABAQUS Explicit dynamic analysis)

选取四个点，自动判断是否在一个平面上。同一个平面上。则绘制一个多边形。不在一个平面，则以前三个点为底面，构成一个椎体。支持Move等转换命令，存图与开图，实现Jig交互绘制等。(Four points are selected to automatically determine whether or not they are on a plane. On the same plane. Draw a polygon. If it is not in a plane, the first three points are at the bottom, forming a vertebral body. Support Move and other conversion commands, save and open maps, Jig interactive rendering, etc.)

说明：  空间计量Elhorst的所有程序，已经加载了matlab的计量程序，可以通过修改读入文件的路径一次性成功。(All the procedures of spatial mathmetrics by Elhorst, which can be successfully operated once by modifying the path of reading files.)
