针对注水肉问题与缺少民用注水肉检测装置的情况,研制了基于超声波能量分析的便携式注水肉无损检测装置,并通过试验对频率分级特征、特征半波、δ0幅值等特征量值进行分析,以确认注水肉检测的特征阚值.研究结果表明:注水肉检测特征半波δ0的幅值4.010 V为阈值;验证实验结果证明该装置对宰后注水肉的分级精度达到98.8％.%Targeting the water-injected meat issue and lack of the household inspective devices,developed a portable non-destructive ultrasonic inspective device on water-injected meat.Basing on the ultrasonic energy analysis,the final characteristic threshold is confirmed by analyzing characteristic values,like the characteristics of frequency,characteristic half-wave,and δ0 amplitude,through related experiments.As the results imply,4.010 V,the obtained δ0 amplitude of characteristic half-wave,is the final threshold.The nondestructive ultrasonic inspective device on water-injected meat reaches a high grading accuracy of 98.8％.
