摘要：

The H+O-2-->OH+O reaction was reexamined by monitoring OH radical concentrations using cw UV laser absorption spectroscopy in H-2-O-2-Ar test gas heated by 1850-3550 K shock waves. The rate coefficient expression (1.0+/-0.1)X10(14) X exp(-7690+/-250 K/T) cm(3) mol(-1) s(-1) was derived. Fitting the present data together with those of Shin and Michael [J. Chem. Phys. 95 (1991) 262] gave k(4),=(7.6+/-0.7)X10(13) exp(-7065+/-140 K/T) cm(3) mol(-1) s(-1) for the temperature range 1100-3550 K. The reverse reaction rate coefficient was found to be (9.3+/-0.8)X10(12) cm(3) mol(-1) s(-1) independent of temperature from 1850 to 3550 K.
