| Abstract: | By adopting the technology of tunable frequency modulated laser absorption spectrum, we accomplished firstly to measure CH 4 absorption spectrum near 3325 nm in the mud gas (simple physical treated) using tunable diode lead salt laser in China,in which the measurement of highly resolving power has great significance in the practical use. |
