摘　　要：目前高精度磁测磁异常的计算公式,大多沿用1993年地面高精度磁测技术规程中的计算公式,笔者在前人研究的基础上并结合自身多年的工作经历,发现该计算公式在计算磁异常值时有一定的局限性,受人为因素影响较大,为了使磁异常的计算简便实用,笔者根据地磁场的构成,推导出了磁异常的通用计算公式。At present,the calculation formular of high precision magnetic anomaly mostly still uses the formular in the high precision surface magnetic measurement technical regulation 1993.Based on the predecessors study and in combination with ourselves experences in many years,we think that there is a certain limitation in it,with lots of influence of artificial factors.For the sake of convenience and practice in the calculation,we have deduced the general calculation formular based on the construct of geomagnetic field.
