摘　　要：This paper develops a modified Tait equation of state （EOS） for trans-decahydronaphthalene with four parameters A, B, V0 and P0 being treated as linear functions of temperature. The coefficients contained in these functions are determined through fitting the experimental compression data in the literature between 293 K and 446 K and at pressures from 10 to 200 MPa. Expressions for the thermal expansivity, isothermal compressibility and thermodynamic quantities are deduced and the numerical results are analytically derived. The numerical results show that the precision of the modified Tait EOS developed in this paper is superior to the EOS in the literature.This paper develops a modified Tait equation of state （EOS） for trans-decahydronaphthalene with four parameters A, B, V0 and P0 being treated as linear functions of temperature.
