| 摘 要： | Gaubau等人于1978年提出的参考台技术,从理论上完全消除了计算张量阻抗时所具有的偏倚误差。但在实际测量中,参考台的距离多大才合适,尚无定论。本文所给的实例,采取了固定主测台、移动参考台的方法。结果表明,参考台距离从20 km变到40 km不会给测量结果带来明显的变化。

| Abstract: | The reference station technique proposed by Gouban et al. in 1978 completely removes the bias in computing tensor impedance. In the measuring example given by this report, the measuring station is fixed and the distance between measuring station and reference station is changed from 10 km until 40 km. The tensor impedance curves are compared for different reference distance. The results show that from 20 km to 40 km, the tensor impedance curves are nearly the same. |
