摘要
利用瑞雷面波在近地表传播特点，用大小阻尼二乘法迭代反演近地在低速带厚度和速度，给出了大庆两个地区实例试算结果，表明该算法是稳定的，适用于近地在参数反演。
Seismic exploration techniques are increasingly developed. Some regularnoise wave is gradually used as useful message. Rayleigh surface wave propogatingcharacter in near surface is used to iteratively inverse near surface low velocitv zoiiethickness and velocity by mininum damping squares mdethod.The compultational resultsof real example in two areas of Daqing say that this algorithm is stable and is applicableto near suface inversion
