【摘要】 <正> 频率测深最近几年在国内很多地区开展起来,但实际工作中遇到的许多问题仍未得到解决。众所周知,在复杂地形条件下,频率测深工作较难进行。特别是对于预先设计的物理观测点、发收距和布极方向,如果恰好发射或接收点位于复杂地形上(悬崖、河流等),为了使观测得以进行,通常将发射或接收点平行移动一定的距离,这就使得实际的布极方向偏离设计的轴向或赤道向,给观测结果造成误差。本文讨论了目前广泛应用的电偶源发射时,由于实际布极方向偏离轴向或赤道向时,影响观测结果的程度。更多还原

【Abstract】 In the field work of frequency sounding, there are many problems remain- ed to be solved. It is known to all that it is difficult to carry out measurement in the varied topography. If the measuring points, space between transmitter and receiver as well as array direction have been designed beforehand, but in the field the transmitting point or receiving point is unfortunately just located in the varied topography (such as cliffs or rivers) and so we move parallelly the transmitter or receiver to a certain distance to conduct the measurement. Accordingly the actual array direction will deviate from the direction of axis or equator designed initially, resulting in the errors of the measurements. In this paper, the author discusses the errors resulted from the effect of array direction deviating from the direction of axis or equator in frequency sounding transmitted by electrical dipole.更多还原
