本文研究分析了安徽10个土类,254个土壤样品的Mn、Fe、Cu三元素的含量,结果表明:成土母质和成土过程,对其有明显影响;另外,对Mn、Fe、Cu三元素在0～100cm土层中的迁移特征的分析表明,在土层中的迁移能力是Mn>Fe>Cu。土壤水分对Mn和Fe的迁移有明显作用,多为在土壤底层淀积;而Cu在土层中的分布,则多有表层积累,底层含量低的特征,并且土壤水分对其影响不明显。
In this paper, the contents of Mn, Fe and Cu in 10 soil samples and 254 soil samples from Anhui Province were analyzed. The results show that the soil parent material and the process of soil formation have a significant effect on Mn, Fe, Cu. The analysis of the migration characteristics of the three elements in 0 ~ 100cm soil layer shows that the migration ability in the soil layer is Mn> Fe> Cu. Soil moisture has a significant effect on the migration of Mn and Fe, mostly in the bottom layer of the soil. However, the distribution of Cu in the soil layer is characterized by accumulation of surface layer and low content of bottom layer, and the effect of soil moisture is not obvious.

买官卖官，实则是一种权力买卖。戴上这顶官帽才拥有这方权力，为了这方权力不惜重金购得一官半职。官和权似乎从来就是一对孪生兄弟，当官就有权，因为有权才想当官。买官卖官这一吏治腐败的兴盛，写照出芸芸众生对权力的渴求心态。 除此之外，还有另一种权力买卖。某市在国企改革中推出一项举措，花钱买权。怎么办呢？该市１４个企业主管局均靠收取企业管理费度日，企业改革必然触动他们的既得利益，由此对改革进行抵制和抗衡。
