(1) The jump compression of shock waves reaches almost all the exchanges of
detonation and energy releasing.
(2) The endothermic reactions rapidly drop down the pressure inside detonation
wave area from N to P.
(3) After endothermic reactions, the
fl
flat transition interval of P-W
′
forward to
under-pressure detonation W.
(4) The transportation rate is the constant self-preserving/simulating expansion
area W-D
′
, which is in direct proportion to D
′
−
(CW + uW).
(5) The area below D
′
is the sparse area of sputtered explosion productions.
All exchanges in detonation are shown in Fig.

The pressure
flat-forms deserve the attention, which are the key features of the
constant self-preserving/simulating expansion area in the structures of under-pres-
sure detonation. There is no pressure
fl
flat-form if detonation structures are different.
Above, the special detonation of liquid explosives is discussed. In the detonation
wave range of under-pressure detonation, there is constant
fl
flat-form
of pressure. After the feature is proved, there will be potential applications in
explosion industry.

2.2.2.2 Eigenvalue Detonation of Liquid Explosives
The classic detonation theory has proved that the stable/steady detonation waves of
explosives propagate with CJ rate and there are sonic
flows in the boundaries of
detonation reactions. If the detonation waves propagate faster than CJ rate, there are
subsonic
fl
flows in the boundaries of reactions. The classic detonation theory pre-
dicted that there were sustaining stable/steady detonation waves and possible
special unsustaining detonation waves. The spread rates of ultrasonic waves in the
boundaries of reactions are eigenvalue detonation rates.
