摘要
通常在介绍用自然电场法确定地下水流向时,只提到“8”字形,而实际工作中发现自然电位的平面分布不仅有“8”字形,还有玫瑰花形。本文用数学物理方法,结合水文地质原理,对这两种类型的理论和实测曲线作了进一步的分析,指出玫瑰花形是由地下水沿多方向流动产生的过滤电场的迭加所致,为解释多轴向的自然电位曲线提供了理论依据。图7,参3。
Usually, the shape of '8' was covered only when we recommend the flow-direction of underground water was determinated by the self-potential method. In fact, the distributions of spontaneous potential have both the shape of '8' and the shape of rose. This paper makes a further analysis about the two types of theoretic curves and the field curves by combinating the mathematic—physic method with the principles of the hydrogeology. And it shows that the shape of rose is caused by the several flow—directions. So this provids the theoretic grounds for the interpretation of the sever al-aix-SP curves. 7figs., 3refs.
