本文从理论上和实验上都表明，情况并非这样，可变电荷表面的电位强烈地依赖于电解质浓度，并且其表面电荷密度既依赖于溶液pH值也依赖于电解质浓度。

From the discussion in thes paper , it is clear that the surface potential of variable charge surface is strongly dependent on the electrolyte concentration .

因此H＋转化为表面正电荷的能力与土壤中氧化铁的含量密切相关，从而可变电荷土壤中H＋转化为表面正电荷的贡献比恒电荷土壤中的大。

Therefore , the ability of this transformation is strongly dependent on the contents of Fe oxide , and consequently the transformation in variable charge soils is larger than that in constant charge soils .

The adsorption capacity of the three red soils was controlled by pH and CEC . High pH and CEC soils adsorbed greater quantities Cd than did low pH and CEC soils .

可见随着离子强度增大，Na+与Cu2+发生竞争吸附，恒电荷和可变电荷土壤对重金属Cu的吸附能力都减弱，但恒电荷土壤的降幅较大。

It is clear that with ionic strength increase , Na + could compete with Cu2 + , the capabilities of Cu adsorption in constant and variable charge soil lowered , but the decline in constant charge soil was more than that of variable charge soil .

同为可变电荷土壤，红壤PZC低于砖红壤，而可变负电荷量比砖红壤高。土壤表面电荷特征的差异，与它们的粘土矿物和铁、铝氧化物的组成和含量不同有关。

These differences between permanent charge and variable charge soils are related to the composition and the amount of soil clay mineral and Fe , Al oxides .
