摘要
在前人研究的基础上,针对用质子磁力仪进行岩(矿)石标本磁性参数测定和计算过程中遇到的测定位置含糊不清、T0取值单位不正确、标本面的编号混乱以及出现负磁化率等问题,从最初对磁秤法测定磁参数高斯位置的定义和公式推导过程入手,从原理上分析了质子磁力仪与磁秤法测定磁参数的不同之处,对质子磁力仪标本测定时的高斯第一位置和高斯第二位置、标本面的编号、测定顺序、地磁场的取值单位等进行明确说明,同时对视磁化率出现负值的原因进行分析,并提出了相应的改进措施,对今后用质子磁力仪进行岩(矿)石标本磁性参数测定和计算有一定的帮助。
Determination and calculation of magnetic parameters of rocks and minerals are faced with some problems such as ambiguous location determination,incorrect units of T0,ID confusion of specimen surface and negative magnetic susceptibility.On the basis of previous studies and starting with determination of Gauss position using mechanical magnetometer and formula derivation,this paper first analyzed the difference in principles between proton-type magnetometer and mechanical magnetometer,and then clearly explained Gauss first position,Gauss second position,the number of specimens surface,the order determination and unit of geomagnetic field.The cause of negative magnetic values were also analyzed and the measures for improvement were put forward.The results obtained can be of some help to the determination and calculation of magnetic parameters of rocks and minerals.
