The algorithm of the original first - arrival picking up module and positioning module are also modified . three , the automation and graphic handling of automatic and manual picking up first - arrivals of direct wave are carried out with vc + + 6 . 0 visibility programming techniques . all processes are accomplished by operator - machine interaction 使用visualc ~ ( + + ) 6 . 0可视化编程技术，实现了直达波初至拾取的计算机自动化和可视化，以及直达波初至的人机交互拾取，整个过程采用了人?机对话方式。
This thesis makes the large quantity of the research work that aims at various problems that exist managing the geological and survey graph by the computer - aided design , and brings upped to the theories and the method that realize the automatic work with the geology and survey . making use of the high program language program development twice to auto cad , this thesis draws up to the complete software package of the geology and survey managing 本论文针对目前地质测量cad技术研究中存在的各类问题作了大量的研究工作，提出了实现地质测量工作计算机自动化的理论和方法，并利用高级编程语言对通用计算机辅助设计软件autocad进行了二次开发，编制完成了相应的地质测量图件管理计算机软件包。
With the rapid development of computer and net technology , it has become a main measure for all walks of life to improve the management skills and enhance the efficiency through establishing information network , therefore realizing the auto - management by computers . railway department , standing at the leading position of chinese transportation , is of no exception . to meet the need of railway locomotive depot , we have worked out mis for locomotive overhaul , in the spirit of iso9000 , trying to realize computer artificial management 随着计算机和网络技术的飞速发展，运用信息技术建立互连网络，实现计算机自动化管理，已成为社会各行各业改进管理、提高效率的一个主要手段，作为一直控制中国运输业的铁路部门自然也不例外，应铁路机务段要求以及科研的需要，我们开发了符合iso9000质量管理标准的机车检修质量管理信息系统，尝试计算机模拟人类质量管理思维对机车检修质量进行管理。
