The main purpose of establishing the analytical model of olfactory sensory information is to utilize measuring gas concentration of the current moment and wind speed and direction information in recent time to in local area to give odor source's existence measurement (yes, no, or unknown). It is generally known that gas sensor is contact measuring device, which can only measure the gas concentration of its space position, and cannot perceive at a distance. Besides, the spread of the gas mainly
