摘要
本文对正态总体分解的算法及其在化探异常圈定中的应用作了研讨。首先论证了无约束最优化技术求解总体分解的拟合参数具有简便、适用、效率高,计算速度快等特点。其次是用实例计算表明了总体分解法用于化探数据处理,对分离矿化异常、确定找矿远景区是有效和可行的。此外还指出,若对同一测区不同范围(子区域)的预测结果无显著差别,则即表明其总体分解的理论假设是成立的,预测结果可靠。
It is proved that the non-constrained optimization method used in soluting fitting parameters of normal population decomposition is simple, convenient, practical and effective, so it is well worth spreading in application also. In addition, an example shows clearly that this method is feasible and effective when it is used in processing data of geochemical exploration, segregating geochemical anomalies and determining prospect areas. It is also pointed out that the hypothesis of the population decomposition can hold theoretically and predicting results will be reliable if predicting results are similar between different subregions in a same survey area.
