摘要：

New theoretical results for the three-particle equilibrium probability distribution function g3(123) for classical hard-sphere fluids are given on the basis of the Percus-Yevick approximation applied to the inhomogeneous pair distribution fucntion in the presence of a third particle, g2(12/3). In particular, comprehensive results are given for three spheres in rolling contact and partial results are given for two spheres in contact with a third particle in arbitrary position. When compared with available simulation data, our results are found to be accurate, and the inhomogeneous Percus-Yevick approach appears to be the first quantitatively successful one for the three-particle configurations considered here.
