摘要：

A unified empirical equation of state for He-3-He-4 mixtures is found in analytical form on the basis of the existing experimental P-V-T data for pure He-3, He-4, and their mixtures in the homogeneous liquid phase in the temperature interval 2.25-4.2 K and pressure interval 0-10 MPa. An algorithm for calculating the fitting coefficients of an approximating expression for P(V,T,c) is constructed. The average absolute error for the determination of P is +/-0.015 MPa.
