Huang-hua' pear fruit was a typical climacteric fruit after harvest, and the fruit senescence-related factors, such as LOX activity, 02" content, AOS activity, ACC synthase activity, ACC content, ACC oxidase activity and ethylene production, changed with peaks at 20 "C. The activities of LOX, AOS, ACC synthase, ACC oxidase and the accumulation of O2 ", ACC content and ethylene synthesis were inhibited when stored at 1癈. And the severity of flesh floss and fruit decay was lightened. Low temperature combined with polyethylene film bag packing (PEF1 and PEF2) could further decrease the rate of weight loss, flesh floss, and fruit decay and keep preferable freshness. When PEF1 and PEF2 packing fruits were transferred to shelf life at 20 "C after storage at 1癈. The activities of LOX, AOS, ACC synthase, ACC oxidase could be suppressed and the accumulation of 02 , ACC content and ethylene production were slowed down to a certain extent, especially during the shelf life after 60 d storage. PEF1 and PEF2 packing fruit could maintain higher firmness as well, and the effects became more distinct along with the storage period, there existed no significant difference between PEF1 and PEF2 treatments.

The results showed that, NO-3-N contents and nitrate reductase activity had obvious diversity in different spinach varieties and different organs of the same plant. The NO-3-N contents in stem were the highest, followed by petioles, then mesophylls, and were the lowest in roots. When the ratio of root to shoot was higher, the NO-3-N contents in plants were lower. NR activity was higher in root especially in lateral root. The NO-3-N contents in mesophyll and petiole were negative correlated with the in vitro -NR activity and in vivo -NR activity in roots.

As the necessary choice of modern cultural creation, self-conscious symbol design always emerges as a specific cultural creation activity by human dealing with the relation to the outside objective symbolic world under specific historical conditions, which is a functional transcendent activity, a programmed cultural creation activity seeking for concreteness against abstractness, and it is also a cultural creation activity with self-discipline, compatibility, and pre-examination value with the ability of self-reflection, self-criticism, self-transcendence and self-creation, therefore, it is a choice of cultural practice which is helpful for us to guide contemporary human cultural creation according to complex situations and it is also one to further control the future and development trend of our culture.

摘 要：作为现代文化创造之必然选择，自觉符号设计在具体历史条件下总是表现为人处理同外界客观符号世界关系的特定文化创造活动，它既是一种功能性超越活动，又是一种不断寻求具体、反对抽象的程式化文化创造活动，还是一种兼顾自律性、兼容性与预验性价值的文化创造活动。它具备自我反省、自我批判、自我超越、自我创造能力，有助于我们按照复杂情况来引导当代人类文化创造，更好地把握自身文化未来与发展趋势。
