摘要：
The critical thermodynamics of a weakly disordered Ising model in (4-epsilon)-dimensional space is investigated by the field theoretical approach. The equation of state is calculated in the second order in the Khmelnitsky square-root epsilon-expansion. Universal combinations of the thermodynamic critical amplitudes are determined on the basis of the equation derived. Estimates of the quantities in three-dimensional space are presented.
