We discussed the relationship between the additional pressure and the stability of disperse system in detail.It was found that the reduction of additional pressure of disperse phase makes the disperse system become more stable.Taking the micro-emulsion as an illustration, the reduction of additional pressure lowers the collision probability among liquid droplets, and more importantly, it is closely associated with the formation of a strong protective film on the droplets.The disperse system could reach the thermodynamic stability state only when the additional pressure of the droplet tends to become zero, and the emulsion becomes micro-emulsion.The above discussion could also be applied to the solid/liquid disperse systems.
