【摘要】 通过采用法国生产的AlphaMOSFox3000电子鼻和自行设计的实验系统,分别对含有活的储粮害虫气体样本、含有死虫的气体样本和标准空气样本进行了检测与比较,并应用主元素分析法进行了模式识别。结果表明,无论虫量多少、虫子死活,它们的气体样本与标准气体样本都有明显的差异,从而能快速检测出粮食是否受到害虫的侵蚀。更多还原

【Abstract】 We use Alpha MOS Fox 3000 electronic nose made in France and the testing system made by ourselves to detect and compare the sample of stored wheat containing dead pests or live with standard air of different smells, and carry out pattern classification with main element analyse method.The results show that without regarding the number of pests, dead pest or live , the smell of the sample is different from standard air evidently. So we can detect whether the wheat is eaten by the pest immediately.更多还原
