摘　　要：小麦的贮藏品质关系到粮食的数量安全和质量安全,对小麦品质的声学检测技术的应用研究进行了综述,首先对农产品的声学特性的概念进行了简述,然后从以下几个方面综述了声学检测技术的研究进展:通过采集并分析小麦粉调制面团过程中的声学特性测定不同小麦粉的品质;或采集并分析小麦籽粒在特定装置中的声音信号来达到测定小麦品质的目的;或通过声学方法测定粮食的密度或采集分析粮仓中害虫的声信号来监测粮仓中小麦的贮藏状态。Quality properties during wheat storage period is vital to food security and safety. In this paper a review of acoustic detection technology for the stored wheat is presented. The definition of acoustic characteristic of agricultural products is reviewed, and then the researches on the acoustic detection technology from several subsequent aspects are summarized： the quality of wheat flour was determined by acquiring and analysising the acoustic signal during dough processing; the quality of wheat was measured by acquiring and analysising the acoustic signal of ke nels in a special device; the storage properties of wheat in the granary was predicted by analysising the grain density, or by acquiring and analysising the acoustic signal of pests.
