摘要
磁参数测量是磁法勘探中的一个环节,对进行异常解释起着至关重要的作用。文章指出了梯度测量方式只是利用磁力仪的"梯度模式"在测量过程中进行日变改正。对高斯第一位置和高斯第二位置给出了明确的定义;指出高斯第一位置和高斯第二位置磁参数计算公式为何不同。讨论了水平测定方法和倾斜测定法之间的关系。对于定向标本指出了剩磁偏角和剩磁方位角的不同,并在最后给了最佳的测量方案。
Magnetic parameter measurement is a key link in magnetic survey and plays an important role in anomly interpretation.During gradient measurement gradient model is applied to make diurnal variation of the measured data.In this paper the first Gauss position and the second Gauss position is defined and the reason why calculation formula of the first Gauss position differs from that of the second Gauss position and the relationship between the horizontal and the tilt measurement discussed.For oriented samples the residual magnetic declination is different from the residual magnetic azimuth.The optimum magnetic measurement scheme is proposed.
