The dependence of the detonation velocity on the initial density is available for several condensed high explosives. It gives a collection of Rayleigh lines on a pressure‐volume plane starting from different initial volume points. It is shown that a collection of the Chapman‐Jouguet (C‐J) states on each Rayleigh line can be described by an envelope function of Rayleigh lines. Based on the analytical expression of the envelope function, formulae for other C‐J parameters are derived.
