以西部地区24种土壤为对象,测定了土壤中的固定态铵、固铵能力、全钾、缓效钾、无效钾、交换钾、交换铵、阳离子交换量、全氮、有机质和pH等,研究了它们与固定态铵之间的关系。

Influence of introducing method and amount of Ca~(2+) on the swelling capacity and cation exchange capacity of montmorillonite;

Ca~(2+)引入方式及用量对蒙脱石的膨胀容及阳离子交换量的影响

To study the effects of pyrolytic temperature on the cation exchange capacity(CEC) of the crop-residue-derived black carbon(BC) and the Pb2+ and Cd2+ sorption on BC,the BC was isolated from the charred wheat residues by pyrolyzing the wheat residues under the oxygen-limited conditions for 24 h at 150,250,300,400 and 500 ℃ respectively.

为探讨热解温度对秸杆燃烧物提取黑碳阳离子交换量和重金属吸附量的影响,在150～500℃范围24h热解小麦秸秆,提取黑碳,测定黑碳阳离子交换量(CEC)和黑碳吸附铅(Pb2+)和镉(Cd2+)量。

The results show that the imperfect saturation increases the cementation factor m and decreases the saturation index n,so that the saturation degree must be inspected and corrected;shale effect scatters the data measured away from Archie formulae,decrease both of m and n,however the cation exchange capacity Q_V correction will improve the correlation betwee.

结果表明,岩心饱和程度不足会使胶结指数m值变大,孔隙度指数n值变小,为此必须检验岩心饱和程度并予以校正;泥质影响使测量数据分散,使m、n值均偏小,经阳离子交换量QV校正可改善与Archie公式的相关性;高饱和水矿化度使m、n值都增大,虽使泥质影响变小,但QV校正仍属必要;高温高压使m值增大,n值减小;油驱后的n值比气驱后大。

The synthetic effects were evaluated through the data of calcium ion exchange capacity,whiteness etc.

通过钙离子交换量、白度等指标评价了合成效果。
