The high absorption energy makes ground water in air containing zone move towards the freezing layer and produce seasonal frozen perched ground water.
它具有很强的吸附能凝聚水分，使包气带水和潜水从液态、汽态向冻结层迁移富集，形成季节性固态地下水。
The utility model has the advantages that the absorption efficiency of an absorption layer is high, the absorption capacity is strong, the using efficiency is high, and all materials can be reclaimed.
本实用新型的优点：吸附层的吸附效率高，吸附能力强，使用效率高，全部材料可回收再生。
