The results show that the flow stress decreases with increasing deforming temperature and increases with increasing strain rate. The flow stress of the alloy during hot compression deformation can be described by constitutive equation in hyperbolic sine function with a hot deformation activation energy of 196.27 kJ/mol. Partial recystallization takes place in the alloys deformed at a high temperature or at a low strain rate, and large number of dislocations and subgrains are observed in the alloy. The elongated grains observed in the samples coarsen with increasing temperature and decreasing strain rate. Correspondingly, the subgrain size increases and the dislocation density decreases. The main soften mechanism of the alloy transforms from dynamic recovery to dynamic recrystallization.

结果表明：Al-Cu-Mg-Ag耐热铝合金在热压缩变形中的流变应力随着温度的升高而减小，随着应变速率的增大而增大；该合金的热压缩变形流变应力行为可用双曲正弦形式的本构方程来描述，其变形激活能为196.27kJ/mol；在变形温度较高或应变速率较低的合金中发生部分再结晶，并且在合金组织中存在大量的位错和亚晶；随着温度的升高和应变速率的降低，合金中拉长的晶粒发生粗化，亚晶尺寸增大，位错密度减小，合金的主要软化机制逐步由动态回复转变为动态再结晶。

According to calculations for the partial derivative of compound function, derivatives of perimeter are deduced.

The affected chicks acquired the morphine conditioned place preference more quickly, and maintained it much longer. Experiment 3 showed that during E5-8, injecting delta receptor antagonist naltrindole reversed the learning and memory impairment caused by morphine while delta receptor agonist DPDPE impaired learning and partial memory function. On the other hand, mu opioid receptors had little effect. As for E17-20, given naloxonazine can reverse the increases of susceptibility to morphine, and the mu receptor agonist DAGO cause the increases of susceptibility to morphine. Delta receptors have no effect.

研究结果发现：经过对鸡胚发育不同时间段的吗啡给药，胚胎期发育E5-8阶段给予吗啡的小鸡学习记忆受损最为严重，表现为学习和记忆功能的严重下降；而E17-20时段吗啡给药的小鸡更容易获得吗啡CPP且保持时间更长。E5-8阶段给予delta受体拮抗剂natrindole能够翻转吗啡对学习和记忆的损害作用，并且给予delta受体激动剂DPDPE也损害学习和部分记忆功能，mu受体作用不大。E17-20阶段拮抗mu受体能够抑制成瘾易感性的增加，激动mu受体可以增加小鸡的成瘾易感性，delta受体没有明显作用。
