| Abstract: | ' A gas sensor of a new type is put forth is this paper. This gas sensor in of N-P structural pattern and works with a high sensitivity. The results in vestigated from theortical viewpoint showed that under conditons , the sensitivity of the compound gas sensor is equal to the multiplication product of the respective sensitivity of two sensitive bodies N and P. The other advantages of this gas sensor over other gas sensors are that it probably has a higher selectivity and thermostability and a smaller zero drift. |
