复印效应

山西沁水盆地CSAMT勘探覆盖点的推断结果表明，阴影和场源复印效应是由地层波所携带的源与观测点之间、源下方真实地质情况的信息决定，是可以利用的。

The deduction of covering points of CSAMT prospecting in the Qinshui basin , Shanxi Province shows that the shadow and source overprint effects are real geological information carried by formation waves between the transmitting source and the observation point or beneath the source , which can be exploited .

由地层波与地面波之比给出了定量划分场区的方法，每一场分量最佳记录规则下的条件和判断是产生阴影和场源复印效应的前提。

The methods of quantitatively dividing zones , the conditions of the optimum record rule for each component and the prerequisites for causing shadow and source overprint effects are provided by the ratio of formation wave to surface wave .
