摘要五个品种的苹果从5到25厘米下降到压电冲击力传感器。测定的影响参数与冷藏和CA储存250天期间的瘀伤体积有关。瘀伤体积的变化/吸收能量的单位变化首先略有下降，然后随着储存时间的推移显着下降。每单位接近能变化的损伤体积变化量随贮藏时间的延长而增加，但品种间和贮藏类型间存在差异。冲击接触时间增加，在存储时间与品种之间的差异。（峰值力/时间峰值力）比，F/T，是高度相关的方法能量和存储过程中下降。
ABSTRACT Five varieties of apples were dropped from 5 to 25 cm onto a piezoelectric impact force transducer. The measured impact parameters were related to bruise volume during 250 days of refrigerated and CA storage. The change in bruise volume/unit change in absorbed energy first declined slightly followed by a significant decrease with storage time. The change in bruise volume per unit change in approach energy increased with storage time with differences between varieties and type of storage. Impact contact time increased during storage time with differences between varieties. The (peak force / time to peak force) ratio, F/T, was highly correlated with approach energy and decreased during storage.
