摘　　要：简要介绍了波动方程静校正的发展过程和基于Born近似的波动方程静校正的基本原理及其应用条件。用曲地表条件下的理论数据和实际数据对开发出的基于Born近似波动方程延拓静校正方法进行了测试。结果表明 ,在常规高程静校正、层析静校正、克希霍夫静校正和波动方程静校正中 ,波动方程静校正的精度最高 ,而高程静校正的精度最低。The development course of wave equation datuming is reviewed, and the principle and application conditions of wave equation datuming based on Born approximation are briefly described. The proposed methods are tested on modeling data and real seismic data from areas of rugged topography. It is showed that wave equation datuming has the highest precision and the elevation static correction lowest among conventional elevation static correction, tomographic static correction, wave equation datuming, and Kirchhoff datuming.
