The results show that a higher accurate forecasting on the infiltration route can be obtained with few samples by this method.

结果表明：该方法能在小样本、高精度要求下对浸润线进行准确预测。

The pole-leaching experiment was also undertaken under the condition of different granularity, leaching agent concentration, infiltration velocity and infiltration route etc.

为了评价矿石的可浸性，采用柱浸试验探讨了矿石粒度、溶浸剂浓度、渗滤速度、渗滤路径等条件对过程的影响。
