二维井间模型势函数重建

本主考虑在边界脉冲源激发下，二维波动方程的势函数反演问题．利用并间测量数据及地表测量数据重建势函数ｑ（ｘ，ｚ），利用反演问题的算子方程形式，通过Ｆｒｅｃｈｅｔ导数及对时间卷积的方法，得到了重建ｑ（ｘ，ｚ）的迭代方法．

On Coefficient Inversion for 2-D Waye Equation

This paper deals with the coefficient inversion.for 2-D wave equation. Forboundary impulse excitation,we take the data measured both on earth surface andon vertical wells as additional information. By converting our inverse problem intoan operator equation,we propose a scheme to recover potential function q(x,z) bythe Frechet derivative operator.
