Seening that the safety detection device can’t detect poisonous and combustible liquid dangerous goods which have volatile characters

a new way is presented that the odor identification function of electronic nose is used

then integrating odor identification technology of the electronic nose with X-ray detection technology

the flow characters of floating gas in container are analyzed

and the position and number of electronic nose are given.Results of experiment show that the probability of dectecting the dangerous goods is reached 85 %.The application of electronic nose can overcome exparte shortcoming of identification of X-ray safety detection device

the full-scale detection for dangerous goods is realized and the performance of the safety detection device is improved.
