The patterns of near field and far field are compared through experiment. Considering the fact, an experiment is made on the testing error caused by distance error and frequency drift.
考虑到实际应用，对距离标定误差和频率漂移引起的测试误差进行了实验研究。

With real examples, the optimal distance between following-vein drift and ore body with respect to the ore deposit diversity is.
