| 摘 要： | 在证明典型跨孔方式所获投影数据提不完全的基础上，首次提出了四种在采用离散图像重建技术进行地震透射波走时反演层析成像时的完全投影数据的采集系统，并比较了四种采集系统所获数据在迭代反演时的收敛速度，最后给出了模型试验结果。

| Abstract: | The author proves that projection data acquired by traditional crosshole sys tem is not enough for inversion and puts forward four typical data-gathering systems that can provide enough projection data on inversion tomography of traveltime of seismic wave by breakdown imag--rebullt technique. Then their speeds of the above four systems on iterative inversion are compared.The result of model test is presented finally. |
