| 摘 要： | 直流电测深（DCS）与瞬变电磁测深（TEM）的视电阻率有较大的差异，在进行联合反演时，重叠观测部分通常采用二者的平均值作为联合反演数据，存在视电阻率曲线衔接产生假异常，以及未能体现不同勘探方法对同一电性体的探测所起的作用不同的问题。文章提出一种多次平均加权接点处理方法，经模型实验和实际应用证明该方法能提高联合反演精度。

| Abstract: | Considering a great difference ot apparent resistivity values of the two methods are usually adopted as joint inversion data for the overlapping observing parts as the joint inversion is in operation. Since there are fake anomalies of the curves＇ connection for apparent resistivity, and no reflection of different effects on detecting the same electrical body by using different exploring methods, it has put forward a multiple mean weighted contacting-point processing method which has already been verified by model experiment and practical application for its enhancement of the precision of joint inversion. |
