where r is the relaxation time and ae the equilibrium value at p and T. Eqs. (25) and (26) are similar to the corresponding equations of Sedney's, except for the different meaning of f\. All the terms on the right-hand side of Eqs. (25) and (26) are known from the given boundary conditions behind the shock, which may be evaluated from the frozen conditions. Solving Eqs. (25) and (26) for dg/ds and dd/ds, one obtains
