| 英文摘要: |
| This paper presents the technology of detecting flammable gases with dual infrared wavelength lights and the design of the gas detection facility. The circuit is improved by analyzing the detecting principle. The results show that the environmental influence is reduced and alarms would not respond to non flammable gases. The reliability and sensitivity of the circuit system are improved as well. |
