@ABSTRACT = The delay and features of the ignition of a stoichiometric 
hydrogen-air mixture at temperatures of 830-1450 K and pressures 
of 2-21 atm downstream of the reflected shock wave have been investigated. 
The experimental data obtained were compared with the results of calculations 
done in accordance with the known kinetic schemes of hydrogen combustion. 
The influence of the interaction of the reflected shock wave with 
the dynamic boundary layer on the ignition and the time of induction 
in a shock tube has been examined.
