Thereby, this dissertation attempts to make a holistic study of attitudinal meanings, trying to figure out how linguistic resources can be employed for the meaning potential of appraisal within the framework of SFG, and how appraisal may be perceived dissimilarly across languages and between interlocutors.

有鉴及此，本文希望对评价话语作一个综合的研究，从而归纳出系统功能语法中的各种语言资源是如何可以运用于实现评价这一意义潜势的，同时探讨对评价的理解是如何因为使用语言的不同和交际双方的不同而存有差异的。

This system has all-sided functions and is compact and practical. It can get screen images, windows or course lists of the target computer, and can record and distill the distance keyboard events, open or close any directory of the target computer, realize the resource share and upload/download files, and capture the audio or videl signals, and so on. The system has a very good generalization and application value.

There was the apoptosis of neurocyte companied the chicken encephalomalacia. The number of apoptosis was affected not only by the content of free radical but also by the function of anti-oxidant system.

在雏鸡发生脑软化的过程中伴有神经细胞凋亡的现象，神经细胞凋亡的数量不仅受体内自由基含量的影响，同时也受到机体抗氧化系统功能的影响。

Meanwhile the function of antioxidant defense system increased to enhance the ability for clearing free radical and antagonized the damage to organism from free radical. So the activity of GSH-Px and T-AOC enhanced. But the compensative ability was limited and the activity of GSH-Px decreased abruptly and the T-AOC was not increased further in cerebellum of chicken with encephalomalacia. This showed that it existed the exhaustion of GSH-Px in cerebellum of chicken with encephalomalacia.

在体内自由基蓄积的同时，机体抗氧化系统功能出现代偿性增强，提高自由基的清除能力，以对抗自由基对机体的损伤，表现为GSH-Px活性和T-AOC的增强，但机体的代偿能力是有限的，发病雏鸡小脑中GSH-Px活性的突然降低和T-AOC的不再增高，表明GSH-Px在发病雏鸡小脑中存在耗竭现象。
