Materials and methods The experiment adopted simulative contamination soils.
It declares that the affinity of OH- icons to Fe3+ and Fe2+ in the soil is stronger than that of Cd2+.On the other side, acidic materials coming from the soil restoration process through ferric sulfate salt may be neutralized by adding lime.

Nanometer materials have different properties contrast to bulk materials, such as mechanics, optics, electricity and magnetism properties etc. [1一3].
For the measuring accuracy of sensors, the TCR of sensitive materials must be reduced to the best.

Introduction The theory research of ER technology is one of the hot topics of smart materials field.
It means that the macro-characteristic intensity of capture effect is related to the pressure gradient, and different ER materials have different critical value which is related to the macro-characteristic intensity of capture effect.
