The Application of HITRAN database in the exploitation of methane measuring instruments
2008
Coal mine gas accident has seriously hampered coal mine production safety. It has practical significance to development of a portable optical detection apparatus. Use HITRAN Database to study methane near infrared spectral. Choose 1331.5nm and 1653.7nm two wavelength as the main research subjects, Study their absorption characteristics and other factors on the absorption of interference. The results show that 1331.5nm more suited as a promotional device detection wavelength, other gases have little affect in this wavelength, but the impact of temperature should not be overlooked, in order to improve the accuracy of detection is needed to temperature compensation.
