用Motif工具库设计地震正演模拟系统人机交互界面

Ｍｏｔｉｆ的功能概要地说就是对各种Ｗｉｄｇｅｔ的创建、管理和回调。利用Ｍｏｔｉｆ工具库为该系统设计人机交互界面的主要步骤为：根据有限元法地震正演模拟系统的总体结构，编程设计系统各层次结构的接口界面，主要包括主窗口、菜单拉杆、下拉菜单和绘图基的创建以及模型数据输入和图形的绘制。有限元法地震正演模拟系统的总体结构由四个层次的内容组成，其主要功能是：输入模型参数和排列参数（包括激发、接收参数）；进行有限元法地震正演模拟计算；修改模型参数并重新进行计算。

A SEISMIC MODELING INTERACTIVE INTERFACE DESIGNED BY USING MOTIF LIBRARY

Main functions of the Motif library are to design, to manage and to call back all kinds of widgets. A seismic modeling system includes four functions, that is, to input the model and arrayparameters such as source and receive parameters, compute the finite element seismic modeling, modify the previous model parameters and recalculate the seismic modeling. According to these functions, the interactive interfaces designed by using the Motif library are main windows, menu bar, pulled down menu and drawing area, and data input and drawing of maps.
