查询词典 of the period

The results indicate that, during the early storage period under short time treatment with heat air, the activities of amylase and polygalactouronase are effectively decreased; starch content reduction is inhibited; the degradation speed of pectin and the decrease speed of flesh hardness are slowed down, and the release rate of ethylene in fruit is decreased. During the later storage period, the decomposition rate of middle lamella and primary wall of the Li jujube fruit treated with heat air for a short time is delayed, exosmosis of cell contents is inhibited, and the cell structure is protected, so the storage time of Li jujube fruit is prolonged.

结果表明，梨枣采后贮前短时间热处理能有效地降低早期淀粉酶和多聚半乳糖醛酸酶活性，抑制淀粉水解，延缓果胶降解，降低乙烯释放量，延缓果肉硬度下降速度，后期能延缓果肉细胞中胶层和初生壁分解，阻止细胞内含物外渗，保护细胞的结构，从而延长了贮藏保鲜期。

The paper summarizes the ecological ethical thoughts of Pre-Qin Period in four aspects: the mode of production, the mode of consumption, the mode of development of technology and the mode of society, using the integration of"growing according to time"and"forbidding according to time"to sum up substantial development in Pre-Qin Period.
