摘要
A semi-empirical wide-range equation of state of compounds of lithium isotopes with hydrogen isotopes is proposed. This equation allows thermodynamic properties to be calculated both in the range of comparatively small densities, pressures, and energies available for experimental studies and in the range of superhigh densities, pressures, and energies where the states can only be estimated at the moment by calculations in accordance with theoretical models. The equation of state contains empirical functions, which allow the composition of the isotopes and the influence of the hydroxide admixture on the compound properties to be taken into account. The capabilities of the equation of state are demonstrated by an example of the description of experimental and numerical data characterizing thermodynamic and thermophysical properties of several compounds of lithium and hydrogen isotopes.
