摘　　要：采用433 MHz声表面波谐振器串联电路对番荔枝储存时间进行检测。将番荔枝样品串联接入检测电路,采集声表面波谐振器的负载频率数据。试验结果表明,随着番荔枝样品储存时间的延长,声表面波负载频率呈现下降的趋势。根据检测频率线性回归结果,可以判定番荔枝样品的储存期时间。该方法具有响应快、重复性好、成本低等优势,有望于水果储存时间快速检测中得到应用。A 433MHz surface acoustic resonator （SAWR） serial circuit was used for Annona squamosa storage time analysis in this paper. Artnorta squamosa samples were serial with the detecting circuit, and output frequency data of SAWR was measured and recorded. Experimental results demonstrated that the SAWR frequency declined with the increase of Annona squamosa storage time. Sample storage time could be decided by linear regression results of SAWR frequency. The proposed method presents advantages including rapid response and low cost. It is promising in fruit storage time rapid detecting applications.
