| 摘 要： | 介绍了大地电磁方法中远参考观测方式的基本原理。通过实例证明了远参考方式的有效性 ,并给出了不同频段远参考点和本地测点之间的一个合理的距离。在高频段远参考点至本地点相距 10～ 2 0km为好 ,中频段 50～ 10 0km比较合适 ;低频段应大于 10 0km

| Abstract: | Results of more than thousand filed measurements show that the remote reference technique is a powerful tool for improving the MT data quality, especially for the noisy environment. Experiments indicate that a reasonable spacing between the local station and the reference station is important for different frequency bands. For high frequency band 10～20km is better. For middle frequency band 50～100km is reasonable. For low frequency band the spacing should be greater than 100km |
