SUCCESSFVL PERFORMANCE OF WAVE EQUATION MIGRATION BY MODEL-150 COMPUTER SYSTEM
本文叙述了在没有磁盘设备的150机上实现出15°和45°波动方程有限差分法偏移的方法.对程序设计和资料处理中遇到的几个问题——边界影响、速度使用、误差影响以及原始资料的能量均衡等给出了一些解决办法.
This paper deals with the successful performance of finite difference migration method of 15°, 45°wave equation by model-150 computer system with no disk equipped. Certain solutions to the problems used to crop up while programming and processing are suggested. Those problems are the boundary effect, velocity determination, error influence, energy equalization of orignal data etc.
