By using Morris Maze task,The results indicated the learning and memory impairment was continuously maintained by MA-induced neurotoxity,PF_(11) significantly antagonized the learning and memory impairment by MA-induced neurotoxicity, Motor incoordination was studied by using the rotating rod method in mice,PF_(11) markedly alleviated the injury induced by MA.using HPLC-ECD,there were markedly decrease the contents of DA,DOPAC,HVA and 5-HIAA,PF_(11) markedly antagonised decrease of DA in MA-induced neurotoxicity.

在Morris水迷宫空间辨别性学习记忆实验中，甲基苯丙胺中毒小鼠找到平台的潜伏期明显延长，PF_(11)沈阳药科大学硕士学位论文中文摘要能显著缩短延长的潜伏期。转棒实验表明，甲基苯丙胺中毒小鼠运动协调性显著降低，而PF；；能桔抗小鼠运动协调性的降低。甲基苯丙胺中毒小鼠大脑内多巴胺及其代谢产物DOPAC、HVA含量明显降低，另外，5一羟色胺的代谢产物5－HIAA明显降低，而PF；；与甲基苯丙胺联合给药小鼠大脑内DA、HVA的含量显著升高。这些结果提示PF；通过影响多巴胺神经系统而桔抗甲基苯丙胺神经毒性的作用。

In the device fabrication, first by the low implantation on the top of the device the isolation between elements in arrays is achieved, and then the deep implantation on the upper layer down to the active layer can provide the transverse current confinements in individual elements in arrays. At the same time the thermal interaction between elements in arrays has also been studied.

在四次质子注中国科学院博十学位论文摘要入制备VCSEL列阵器件的设计中，一方面通过对外延片上DBR反射镜的较浅的质子注入形成高电阻区域实现对列阵器件中的单元器件之间的隔离，另一方面通过再次的较深度的可以达到有源区上表面的质子注入形成高电阻区域实现对单元器件中注入电流的限制作用c在对VCSEL列阵器件的设计中，对单元器件之间的热相互作用也进行了分析。

By taking advantage of SQL, we obtain an effective algorithm for extracting fuzzy association rules in fuzzy database in Chapter 4. Moreover, we establish generalized concept lattice in generalized rough approximate space by using lattice theory, and obtain a fast algorithm of extracting useful rules for making decision.

在本学位论文的第四章，作者通过在模糊数据库中引入SQL数据库查询语言，得到了一个模糊关联规则的高效挖掘算法；并且在广义粗近似空间中，通过与格论知识的结合，我们重新构建广义概念格，从而快速高效的发现采掘其中蕴涵的有用规则，为人们决策提供帮助。
