摘要

针对Waldhauser提供的双差地震定位程序中使用静态数组致使内存浪费的情况,使用动态分配数组,按需分配内存,减少了内存的浪费。原程序最低内存需求1.4G的地震定位示例,在改进程序中只需256MB内存就可运行,且定位速度不变。
Considering that the double-difference relocation program provided by Waldhauser wastes lots of memories because of using static array,a new method to improve the program by use of dynamically allocatable array is presented.The example offered along with the programs can run on 256MB instead of 1.4 GB memory with the same speed.
