【正文】 k in dealing with the main problems of sensor array data: the quality of black tea, tea from different tea gardens picked by different climatic conditions, farm type, season and planting methods are quite different, and therefore, the entire database can not be readily be met difficult to train a neural work model. The study proposed to enhance the learning characteristics of RBF neural work pattern recognition algorithms to classify the smell of black tea, and get a better recognition effect. In addition, the Task Force also uses an electronic nose to predict the optimum fermentation time for black tea. Wang Jun, et al Zhejiang University to study electronic nose applications in various types of food, such as Longjing tea, wheat, eggs, etc., have achieved better results. Luo Dehan such as China Science and Technology University of Electronic Nose to the counterfeit cigarettes identification, Huazhong University of Science and Technology, Xie Changsheng electronic nose to identify 17 different brands of domestic vinegar. Medicine With the development of electronic nose technology and its application in the field of medicine is being increasingly popular. ERThaler in electronic nose applications early, in order to verify whether it applies to the field of medicine do exploratory test. The experiments showed that the electronic nose can better distinguish the cerebrospinal fluid and plasma, high accuracy, you need a small amount of sample. The experiment took the first step to explore the feasibility of electronic nose applications in the field of medicine. Clinically, the electronic nose for evaluation of halitosis。 given a meaningful analysis of the control by analyzing the gas exhaled by people with diabetes or excreted in the urine。 detect ear, nose and throat infections reach up to 88% accuracy。 also used to assessment of the unpleasant smell 無錫科技職業(yè)學(xué)院科技 論文 The application of electronic nose 12 on the pill, the patient39。s renal function, mental patients appreciate. The electronic nose in another medical application is the detection of cancer. The proposed electronic nose Italy and other noninvasive diagnosis of early cancer of the urinary tract。 39。Amico pointed out that the electronic nose can distinguish between benign skin lesions and birthmarks tumor or melanoma。 RFMachado etc., Cyranose320type electronic nose Success diagnosed with lung cancer. Cao Mingfu such as Zhejiang University conducted the electronic nose in the early diagnosis of lung cancer, put forward a new electronic nose based virtual gas sensor array and image recognition method for noninvasive detection and diagnosis of lung cancer. In the identification of traditional Chinese medicine, Shen National Day Atractylodes Zhejiang, Ann domestic use of the electronic nose, bran fried Atractylodes soil fried Atractylodes powder detection using principal ponent analysis to analyze the data. The results show that the sample to obtain a better distinction. Agriculture The electronic nose system has been successfully used for crop quality monitoring, detection and fish monitoring of fruit maturity, in addition to used to detect crop diseases caused by bacteria such as fungi, bacteria. The odor can be as important characteristics for detecting the state of health of the crop. Malaysia MAMarkoma and other proposed use of the builtin artificial intelligence electronic nose to detect plant diseases, especially basal rot. Commercial electronic nose Cyranose 320 as a frontend sensor ANN as a pattern recognition method, odor samples collected from the scene classification and recognition in puter. The results show that the system is able to distinguish between healthy and infected plant stems. Australia JHSohn and other electronic nose for continuous monitoring of the chicken farm odor. The results show that the algorithm is based on a specific model, the electronic nose can continuously monitor odor concentration. Environmental monitoring The major environmental issues facing the world today is the toxic chemicals in air, water, soil pollution. Urban air pollution with the growing respiratory disease is closely related, and which some substances (such as benzene) longterm exposure will 無錫科技職業(yè)學(xué)院科技 論文 The application of electronic nose 13 cause cancer. Italy Vito electronic nose system bined with neural work technology is used to predict atmospheric benzene concentration, to monitor urban environment pollution. British and other electronic nose technology for the detection of microbiological and chemical contamination of drinking water. The study is based on two types of sensor array of conductive polymer electronic nose system for the drinking water in the early detection and identification of bacteria, fungi. Using PCA, DFA and cluster analysis can identify through the propagation of bacteria and fungi for 24 hours at 25 ℃ . The Italy39。s latest two technologies solid phase micro extraction and Electronic Nose monitor phenanthrene degradation in contaminated soil. The Philippines is a hydrophobic anic contaminants, contains three fused benzene rings belonging to polycyclic aromatic hydrocarbons. The detection and analysis of the electronic nose results show that, by PCA treatment, contaminated and uncontaminated soil samples can be significant distinction. Public Safety In order to ensure the security of public places, check explosives in airports, railway stations, docks and other places is an important and difficult task. These places usually have more staff, speed of flow of people, plex background, more belongings. Therefore, the accuracy of these places explosives, quick detection has bee the focus of the work and difficult. Compared to traditional detection methods, the electronic nose has small size, low cost, and high reliability. . Yinun and
