The tests of metal absorption and de - absorption on loess and red layer demonstrate that the loess soil is a very strong absorbent to metals . when metals in water - soil solution is high ( > 1 x 10 - 6 ) , absorptive ability for loess in depth and red earth is higher than loess in surface soil . but when metals when metals in water - soil solution is low ( > 1 x 10 - 6 ) , which is much closer to the natural conditions , absorptive ability for loess in surface soil is bigger than loess in depth and red earth
吸附和解吸试验研究表明，黄土对金属离子具有很强的吸附能力：对于浓度较高的水?土体系，深部黄土和红土吸附能力大于地表黄土；而对于更接近自然界条件的低浓度水?土体系( ng级ml ) ，地表黄土吸附效率高于深部黄土，使以离子形式迁移的一部分金属在地表黄土中得以被吸附固定而形成异常，这部分金属可被中性盐提取剂提取。
Thus , metal parts " quality must be inspected before using , can be used in the inspection of metal parts " quality . electronmagnetic test , a nondestructive testing of metal material . because there are many factors which have effect on electronmagnetic test , the qualitative analysis is always a difficult problem
电磁无损检测作为一种非破坏性检测方法，在金属材料无损检测领域得到了广泛的应用，但由于影响电磁检测的因素太多，所以电磁检测的定性、定量分析一直是个难点。
