the shock wave and mergy available for further propagation. There result 
a pair of ordinary differential equations for peak pressure and shock—wave 
energy as functions of distance fram the charge that are easily integrated 
with simple numerical procedures. 
In the present report, these two theories are developed in detail 
forthe shock wave of spherical symmetry. The shock wave of cylindrical 
symmetry from an infinite cylinder of explosive is treated by the methods 
of Kirkwood and Brinkley. Calculations of the shock-wave parameters for 
several explosives by the two theories are compared with each other and 
with the results of experiment.
