本文讨论了反褶积分层解释法的二个重要性质,证明了反褶积法与现用的平均法在“全矿段”上可以认为是基于同一原理,地质特征参数a没有总体效应,因a取值不准在各个分层上引起的正负含量误差是互补的。文章还提出并论证了γ异常微分曲线的对数梯度最大值g_(max)是地质特征參数a的合适取值。在实践中用a=g_(max)进行分层解释,误差小,基本上消除了负含量现象。 This paper discusses two important properties of the deconvolution stratified interpretation method. It is proved that the deconvolution method and the current average method can be considered as the same principle in the “whole ore section”, and the geological characteristic parameter a has no overall effect. a value is not allowed in each stratification caused by positive and negative content error is complementary. The paper also proposed and demonstrated that the maximum value of logarithmic gradient g_ (max) of γ anomalous differential curve is an appropriate value of geological characteristic parameter a. In practice, a = g_ (max) for stratified interpretation, the error is small, basically eliminating the phenomenon of negative content.
