| 摘 要： | 为充分利用已经采集获得的并不完整的瞬变电磁衰减曲线,以一维三层理论模型以及实测数据为例进行了计算,计算结果说明,在不能获得整条衰减曲线时,利用部份时段进行反演获取一定的的地质信息,是一种可行的补救措施。试验的前提是瞬变响应曲线是正常的符合衰减规律的曲线,而对于畸变的曲线是不适合的。

| Abstract: | The three layer model forward data and observed TEM data was calculated to test the effect of the inversion with incomplete TEM data,and it was tried how to make full use of incomplete data.The results show that the inversion with incomplete data can help to obtain additional information about the geological target,and this approach can be a remedy of the exploration especially in noisy area.It is on the base that the TEM decay curve is normal the inversion can be carry out,but it is not reasonable when decay curve is abnormal. |
