As a result of Yukawa potential energy function's model system has become a hot spot, it has concerned us in recent years that the Yukawa fluids density functional theory research had made great progress. This paper takes the density functional theory study on hard core Yukawa depletion potential colloidal particles in the fluid. |

| Yukawa potential function in the simulation of simple fluid, colloidal suspensions is widely used. The Yukawa fluid density functional theory research has made great progress, at the same time, based on the Yukawa potential function model system has become a hot research topic, has attracted much attention in recent years. In this paper the application of density functional theory study with hardcore Yukawa fluid depletion potential of colloidal particles. |

The effect of entropy exists throughout the whole system of chemistry and biology and has a promotion to the exploration of colloidal particles aggregation structure. We apply Density Functional Theory(DFT) to set up a expression of density function of Helmholtz free energy system. In simple density functional method of fluidic, we present the Local Density Approximation(LDA), weighting density approximation and Fundamental-measure theory of Rosenfeld and the depletion force of colloidal particles on related papers which at the same time makes a analysis to the related influencing factors. |
