摘　　要： 从精确度的基本概念入手,基于物探地质探测效果要求,对物探野外生产中通常采用均方相对误差来衡量、评价观测数据质量存在的问题进行剖析;通过建立简单的野外数据观测模型,对高精度物探仪器在深部地质找矿中影响数据观测质量的主要因素进行分析,并提出一些应对的办法或措施。有助于正确认识高精度物探测量的含义,以充分发挥高精度物探仪器在深部地质找矿中的作用,取得最佳的找矿效果。 Based on the concept of accuracy and the requirement on geophysical detecting effect,this paper conducted analysis on the problems occurred in the geophysical field works while using relative mean square error to measure and evaluate the quality of observed data.By setting up a simplified model of field data observation,the authors analyzed the main factors which affected the quality of data observation in the deep geological prospecting works by using high-precision instrument,and they put forward some methods and measures to deal with these factors.This paper contributed to comprehend the implications of high-precision geophysical survey,in order to make full use of high precision geophysical instrument in deep geological prospecting works and to achieve the best prospecting results.
