| 摘 要： | 讨论了电磁波垂直于地层传播时,与反射电磁波干涉产生的驻波,并得出在地面形成波腹与波节的条件。测定波腹频率,就可以根据文中给出的推导方程,计算出地层厚度,以及地层底界面两侧介质电磁参数的相对大小。指出了至少有4个自然电磁波源辐射电磁波,可供人们进行电磁驻波法地球物理勘探使用。

| Abstract: | This paper deals with the standing wave resulting from the interference of the reflection electromagnetic wave when the electromagnetic wave is transmitted and perpendicular to the strata.The conditions of antinode and node formed on the ground are also discussed.According to the equation deduced by the author,the thickness of the strata and the relative sizes of the electromagnetic parameters in the media on the two sides of the bottom interface of the strata can be determined by measuring the frequency of the antinode.It is also pointed out that at least four natural electromagnetic wave sources can be used in geophysical exploration based on the electromagnetic standing wave method. |
