结合对电磁感应方法的研究,先后在野外进行了生产试验及室内模拟实验研究工作。本文就其中几个问题谈点体会,错误之处敬请批评指正。一、对射倾角法的观测精度及异常特征1. 对射倾角法消除地形影响的原理常用的几种倾角法(Bx、Cx)在野外工作中有一个共同的缺点,就是为了保证观测精度,收、发仪器之间需要比较准确地相互照准进行观测。在山区或树多通视条件较差的地区,用上述方法进行普查往往受到限制,尤其是由于地形起伏而引起异常畸变或产生地形干扰异常,影响到方法的应用效果。为了适应于山区林区工作的需要,可采用“对射倾角法”进行工作。
Combined with the research of electromagnetic induction method, it has carried out production test and indoor simulation experiment in the field successively. This article discusses some of these problems, please correct me criticism. First, the accuracy and abnormal characteristics of the observation of the dip angle method 1 The principle of the dip angle method to eliminate the impact of the terrain The common dip method (Bx, Cx) in the field work has a common shortcoming is in order to ensure the accuracy of observation, Receiving, sending instruments need to be more accurate cross-reference for observation. In mountain areas or areas with poor tree-viewing conditions, censuses conducted by the above method are often limited, especially due to the undulation of the terrain which cause abnormal distortion or terrain disturbance, affecting the application effect of the method. In order to meet the needs of the work in mountainous areas, the “dip method” can be used.
