| Abstract: | In recent years, with development of modem industry,increasing complexity of environmental change, and people ＇ s awareness of environmental health is improving. In this case, conventional gas detecting system can not meet requirements, pending the development of a high sensitivity, high resolution new type realtime gas detecting system. From gas molecules IR spectrum theory, and on the basis of comparison of current variety of gas detection method,study on a gas detecting system based on photoaeoustic spectrum（PAS） technology. Experiment verifies that this system can effectively carry out CO2 gas detection. |
