摘要
为避免震源的不确定性及塑性形变的影响，本文讨论了非脉冲响应的一维波动方程系数的反演问题。这一问题可化为积分方程求解。理论上，这是适定问题，但在应用上是不适定的。文中给出了正则化求解方法。理论计算表明，该方法得出的近似解较为稳定。
The coefficient inversion problem of 1-D wave equationfor non pulse responses is discussed here so as to remove seismic source uncertaintyand plastic strain influence. This problern can be achieved by solving for the corre sponding integration equation. It is well posed theoretically but ill posed practically.Its regularization method is given here. Theoretical computation shows this methodbrings quite stable approximate solution.
