The accurate high-pressure and high-temperature effective pair potentials are adopted to describe the intermolecular interactions, which are made to consider molecular dissociation. This paper focuses on a mixture of nitrogen atoms and molecules and is devoted to the study of the phenomenon of pressure dissociation at finite temperature. The equation of state and dissociation degree are calculated from the free-energy functions in the range of temperature of 2000\u201315000K and density of 0.2\u20133.0g\u2215cm3, which can be compared with other approaches and experiments.<\/jats:p>","DOI":"10.1063\/1.2165191","type":"journal-article","created":{"date-parts":[[2006,2,15]],"date-time":"2006-02-15T23:22:27Z","timestamp":1140045747000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":13,"title":["Self-consistent fluid variational theory for the dissociation of dense nitrogen"],"prefix":"10.1063","volume":"124","author":[{"given":"Qi-Feng","family":"Chen","sequence":"first","affiliation":[{"name":"Southwest Institute of Fluid Physics Laboratory for Shock Wave and Detonation Physics Research, , P.O.
