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.

This paper first elaborated the principle of SINS, some interrelated information,and the affect of renewed arithmetic to the system"s precision. Then, we studied thequaternion in traditional renewed attitude arithmetic. The quaternion is simple, andwhen run it into computer, it"s time saving. So, this arithmetic is often adopted byengineering. However, the quaternion brought unexchangeable error inevitably. Whenthe carrying body moves in highly dynamic situation, the error would become larger.So we should take effective measure to get over it.
