摘要：

Cavity ring-down spectroscopy (CRDS) was used to measure absolute concentration profiles of the CH radical in low-pressure methane/air flames. The Q(1)(4) rotational line of the C(2)Sigma(+) <-- (XII)-I-2 band at 315 nm was used for concentration measurements. Very high sensitivity (2 X 10(10) cm(-3)) is demonstrated. The measured profiles are in good agreement with that calculated using the GRI-Mech mechanism. (C) 1999 Elsevier Science B.V. All rights reserved.
