摘要：

This paper deals with the generalization of the standard equation for scattering, 1/S(q) = 1/S0(q) + V, to multicomponent polymer systems and shows that the same result holds if it is written in matrix form. Three different methods are used: the Ornstein-Zernike formalism, the Random-Phase Approximation, and the Edwards Hamiltonian method. We compare these three methods in order to see how they work for multicomponent polymer systems. As a side result, we rederive the Flory-Huggins free energy without using a lattice model, and we generalize this to take into account Gaussian fluctuations in multicomponent systems.
