In the derivation, a theoretical form of Martin-Hou equation was obtained. It had a similar form and the same capability to predict P-V-T properties as the Martin-Hou equation and no additional data were required for evaluating the constants. The characteristic constants of the theoretical expression have certain relationships with the molecular parameters.展开更多

It has the form similar to the Martin-Hou equation of state. The numerical values of the characteristic constants in the equation can be calculatrd by the method of Martin and Hou. The equation can he used to predictP-V-T properties accurately for fluids when the critical parameters (Tc,Pc, and Vc) and one point on the vapor pressure cure are given. By using the functional relationships between the characteristic constants and the microscopic parameters, the molecular microscopic parameters of the substance can be obtained.展开更多
