摘　　要：以利用物探资料寻找隐伏铁矿的工作为例,通过对某地区重磁电十字剖面资料的推断解释,总结了减少物探异常解释多解性的思路与做法,提出在布置外业工作和收集资料时,就应考虑为减少多解性取全取准所需的各类用作约束的资料,认为采用逐一判断—排除的方法是可选途径。Exemplified by the utilization of geophysical data in search for a concealed iron deposit and based on the deduction and interpretation of the gravitational,magnetic and electrical cross-shaped profile data in a certain area,this paper sums up the train of thought and working methods for reducing the ambiguity in the geophysical anomaly interpretation.It is held that various kinds of constraint data should be accurately and completely collected during the field work and data acquisition so as to reduce the ambiguity,and that the one-by-one judgment and exclusive method seems to be an effective way for this purpose.
