本文介绍如何根据电磁波的吸收原理,利用频率为1兆赫的无线电波,在梅纳拉姆铜矿坑道里探寻导电矿体,并对仪器作了描述. 方法方法的依据是对屏蔽系数ε或对高频视吸收系数b_a的估计.ε的定义是:
This article describes how to use the frequency of 1 MHz radio waves to explore the conductive ore body in the Menararam copper mine tunnel based on the principle of electromagnetic wave absorption and to describe the instrument.Method of the method is based on the screening coefficient ε or The estimation of high-frequency apparent absorption coefficient b_a is defined as:
