摘　　要：用圆盘天线电磁脉冲能量传播规律的积分表达式,严格证明了减少激励脉冲的上升时间或提高载波频率都可以降低电磁脉冲传播过程中的能量衰减速率。并以变质岩和火成岩为例,证明了这种慢衰减特性可以在保证精度的前提下大幅度地提高地矿的探测深度,为电磁测矿提供一种新的方法。The integration formula on the propagation of electromagnetic pulse energy which is stimulated by disc antenna strictly proves that reducing the rise time of pulse and improving the carrier frequency can decrease the rate of the decay of radiated energy in the process of electromagnetic pulse.This paper sets metamorphic rock and igneous rock as examples to prove that this characteristic,with accuracy,can greatly improve the depth of electromagnetic detection,which will offer a new method for electromagnetic mineral detection.
