【摘要】 电子鼻是一种模拟生物嗅觉工作原理的新型仿生检测系统,通常由交叉敏感的气体传感器阵列、数据处理方法以及适当的模式识别算法组成,可用于自动检测、分析和辨别单一或复杂气味。电子鼻在食品加工、环境监测、公共安全和医学诊断等诸多领域得到广泛的应用。随着经济持续快速发展和城市化水平的不断提高,恶臭污染事件日益增多,因此自动连续监测的需求越来越迫切,电子鼻也显示了其在环境监测中的应用潜力。文章首先介绍了电子鼻技术的概念、原理、发展历史等信息,研究了电子鼻技术在国内外环境监测中的应用与进展,发掘出电子鼻可应用在突发污染应急快速筛查和污染源排放预警监测等面,最后展望以电子鼻为核心技术的恶臭实时自动连续监测技术的广阔发展前景。更多还原

【Abstract】 The electronic nose is a new Bionic detection system which simulates a kind of modeling of biological smell. It is usually constituted by cross sensitive gas sensor array, data processing methods and pattern recognition algorithms. It can be used to automatically detect, analyze and identify a single or complex odor. The electronic nose has been widely used in food processing, environmental monitoring, public safety and medical diagnosis and other areas. As the economy continues to improve and the rapid development of urbanization, the stench of pollution incidents increasing, so the demand of automatic and continuous monitoring is increasingly urgent, the electronic nose also shows its potential applications in environmental monitoring. The article first introduces the concepts, principles, and history of the development of electronic nose technology, studying the environmental monitoring application of electronic nose technology in domestic and international, exploring that the electronic nose can be applied to rapid screening for sudden pollution emergency and pollutant emissions early warning and monitoring, etc. Finally, we preview the prospects of the stench of real-time automatic and continuous monitoring technology which core technology is the electronic nose.更多还原
