| 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 |
| 2 | Properties of Dispersion Casting of Y2O3 Particles in Hypo,Hyper and Eutectic Binary Al-Cu Alloys显示文摘在现在的工作,在铝铜合金 Y2O3 粒子扔的分散关于 20 的 Cu 内容(低亚硫酸钠)以微结构变化被调查, 33 (eutectic )并且 40 (亢奋)由扫描电子显微镜学( SEM )和精力的 wt %散光谱学(版本)。为 Al-Cu 的制造,合金驱散 Y2O3 陶器的粒子,搅动烧铸方法被采用。在 Al-20 wt % Cu 合金(低亚硫酸钠 eutectic ) 的情况下, SEM 图象表明主要艾尔在开始被长大。在那以后,有很好驱散的陶器的粒子的最容易溶解的阶段被形成。在最容易溶解的作文的情况下, Y2O3 粒子一致地在矩阵被驱散。当 Cu 被增加进艾尔直到 40 wt % 时(高级低共熔体) ,主要没有任何 Y2O3 陶器的粒子, 9 阶段在团结的早阶段被长大。此后,最容易溶解的阶段与很好驱散的陶器的粒子被形成。Y2O3 陶器的粒子主要在 Al-Cu 合金在最容易溶解的作文的情况下被驱散,这能被结束。 | J.J.Park G.H.Kim S.M.Hong S.H.Lee M.K.Lee C.K.Rhee | 2008 | Journal of Materials Science & Technology2008，24，1： | 0 |
