本文根据银河向量计算机并行运算的特点,讨论了波动方程差分法偏移的向量算法。通过理论模型和实际地震资料的处理,说明这种算法的偏移结果是正确的,且比标量算法节省机时。

In the light of the YINHE(Milk Way)vector computer being capable of operating concurrently, the paper discusses the performing of wave equation migration difference by using vector calculus. From the theoretical model as well as the actual seismic data processing, we can declare that the migrated result using this calculus is correct. Also, it takes much less time as compared with that the scalar calculus does.
