英文摘要：

In this paper, the new developments and basic principles of surface plasmon resonance technique are introduced, and its applications in gas sensing are discussed in detail, including toxic, explosive and organic gases etc. The sensitivity, selectivity, reversibility, response time, desorption time and reproducibility of the measurements can be improved by changing materials of sensing films, designing new detecting apparatus, improving methods of fabricating thin films, modifying the thickness of the thin film and so on. Integrating surface plasmon resonance technique with other techniques not only improves sensitivity significantly, but also enable to perform remote monitoring, particularly combine with optic fiber technique. The influence of environmental factors such as humidity and temperature on the measurements is discussed in detail.
