The study on the hardening mechanism of the soft soil with the materials shows that the hardening procedure can be divided into three stages:(1). Hydrating and dissolving stage, when material A and material B of the high-water-content and quick-setting materials respectively dissolve and balance in water.(2). Gel and consolidating stage, when the materials hydrate into calcium crystal and the ion exchange and aggregation of soil particles occur in an alkaline environment.(3). the structure developing stage, when the calcium crystals connect each other, absorb and crystallize the water around; the hydrate remnants, calcium hydroxide, carbonate continuously in water and in the air.

In order to investigate the relationship of solubility between vanadium and the other co-existing ion in soil. The phase equilibria of the quinary systemNaVO_3 + KVO_3 + NaH_2PO_4 + KH_2PO_4 +(NH_2)_2CO + H_2O and its five quaternary sub-systems were studied at 298K with isothermal dissoluble method. According to the reference, all these systems are not reported yet. The solubilities and the physico-chemical properties such as density, conductivity, pH value and refractive index of the equilibrium solutions were determined. Based on the determined values, the solubility stereo-diagram and projected-diagram( saturated with KVO3), projected-diagramsaturated with (NH_2_2CO, and water content diagram of the quinary system, isothermal solubility diagrams of the quaternary sub-systems, and the physico-chemical properties-composition diagrams of the equilibrium solutions were plotted.

At the experimental concentrations tested (00 u.g I/1), selenite and selenate did not significantly affect the accumulation of either mercury species by the green mussels. In contrast, selenomethionine significantly inhibited the uptake of MeHg and enhanced the uptake of Hgy the mussels, but it did not affect the assimilation from the ingested diatoms. We further examined the influence of tissue body burden of Se in the green mussels following pre-exposure to selenite and selenomethionine on the accumulation of Hg2 and MeHg from the dietary and aqueous phases.
