| 1 | Portable System for CWA Detection Using Micro Array Gas Sensor显示文摘Biochemistry weapon is raising new tools of war and terror.This research is an experiment about portable system for CWAs (chemical warfare agents) detection using micro array gas system.CWAs were divided into four types such as blood, nerve,vesicant,and choking agent.To detect various CWAs,semiconductor thick film sensor array based on tin oxide was fabricated and their gas responses were examined.Operating temperature was range of 250℃to 350℃and gas concentration was range of 0.1μg/g to 10μg/g.Sensor array was measured as operating temperatures,concentrations for four simulant agents of CWAs.Extracted parameters from results were carried out classification among CWAs through the principal component analysis (PCA).Also,classification of gases is studied using adaptive resonance theory (ART) that is one of neural network algorithm.Results displayed using PDA system. | J.H.Kwak Y.T.Lim G.H.Kim N.J.Choi H.D.Park G.H.Rue J.S.Huh J.C.Kim D.D.Lee | 2006 | 稀有金属材料与工程2006，35，A03： | 4 |
