So it is a effective prescription of protecting and treating AD.In our experiments, the model ras were administered D-gal intraperitioneal injection and β-Amyloid protein fragment_(1-40) into hippocampus. Mean well we used the technique of optical lens、 electron microscope、 immunohistochemical method, biochemistry and molecular biology.We studied the mechanisms that DR pretect and treat AD from the aspects of apoptosis、 inflammation injury、 oxidative injury 、 cholinergic neuron injury and the behavior experiments at cellar and molecular level.

In this paper, the effects of factors like flotation、cooling velocity on distribution and microstructure of the material were studied under the condition of unidirectional and multidi〓tional solidification, an order of magnitude analysis was performad in order to understand the dynamics of an advancing solid/liquid interface behind a particle as well as the behavior of the particle in front of the interface, and a model of critical velocity for the pushing/engulfment transition of particles by the interface was built, the theoretic result gave a good explain to experimental one.

本文考察了在常规铸造和定向凝固条件下，浮力、冷却速度等因素对SiC颗粒分布以及材料组织的影响，分析了颗粒在凝固过程中的行为以及对界面的作用，建立了在胞状树枝晶凝固条件下枝晶对颗粒的推移/吞并临界速度模型，理论分析和实验结果基本一致。

We firstly discuss minimal sets characterizations of closed-set lattice , then systematically study the categorical properties of categories CL and PairCL by the means of the join-semilattices closed-set-latticefies, and the constructions of monomorphism, epimor-phism, extremal monomorphism, extremal epimorphism, section, retraction, subob-ject, quotient object, product, co-product, equalizer, coequalizer, inverse limits and direct limits in the categories CL and PairCL are given.

首先讨论了闭集格的极小集刻划，然后通过并半格的闭集格化这种方法，较为系统地研究了范畴CL及范畴PairCL的性质，给出了范畴CL和范畴PairCL的单态射、满态射、极端单态射、极端满态射、截节、收缩、子对象、商对象、极端子对象、极端商对象等特殊态射和特殊对象的具体刻划，并且研究了它们的等化子和余等化子、乘积和余积、逆极限和定向极限的具体构造。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
