射线层析成像技术在工程中的应用

On Engineering Application of Ray Path Tomography

由地震射线和电磁波射线组成的射线层析成像技术（ＣＴ）在地学领域已得到了广泛的应用。介绍了地震ＣＴ中的一种基于最短走时路径的射线追踪方法；研究了电磁波ＣＴ中的井间电磁波场强幅值相对归一化方法。应用表明，上述方法是可行的。

The ray path tomography composed of seismic and electromagnetic waves, is widely used in the geophysical prospecting. A ray path trail method based on the mininum travelling time in the seismic tomography is introduced. And a relative normalized method in finding field intensity amplitude for crosshole electromagnetic wave tomography is researched. Engineering practice showed that the above mentioned methods are feasible.
