Items of pH, soil solution K, exchangeable k, nonexchangeable K and potassium fixation index were all determined after incubation. The results indicated similar extent and trends of transformation among three K forms, that is, decreasing content of soil solution K and exchangeable K but increasing nonexchangeable K level were observed in both CaCO3 and SrCO3 treatments of two soils. As to CaCl2.2H2O addition, pH increase was not found and the change of three K forms was not significant when application rate raised.
结果显示CaCO3的添加,除能提升土壤pH值外,亦能使土壤中三种型态钾(溶液性钾,交换性钾,非交换性钾)有显著的改变,且改变程度及趋势均甚为相似,而CaCl2.2H2O的添加不会造成土壤pH的改变,且三种型态钾并不随CaCl2.2H2O用量的增加而有显著改变的现象。

The magnetite with a mean diameter of 8nm was prepared by chemical coprecipitation methods. By the addition of nonionized oleic acid to the suspension of magnetite in solution during precipitation, the magnetite nanoparticles were coated with a double surfactant layer. A gel-like precipitated precursor is then formed because of the hydrophobic interaction among those coated units. By transferring of this precursor to an organic solvent, the surfactant double layer on Fe〓O〓 nanoparticles reduces to one; however, it still remains as a double layer by transferring to an alkaline aqueous solution. Both these cases give in stable colloids of superparamagnetic Fe〓O〓 nanoparticles.
