These results show that there are reciprocal CGRP-positive fiber connections among the MrD of the striatum, amygdaloid nucleus, bed nucleus of the stria terminals and substantia nigra and its dorsolateral area. It is suggested that there is an affinity relationship between the MrD and limbic system.

There was an obvious increase of insulin receptor gene and protein in the cerebral ischemia reperfusion tissues in rats. The positive cells such as neuron, neuroglia cells, vascular endothelium cells possibly participated in regulating the processes of energy metabolism of cells and neovascularization. It implied that the high expressions of insulin receptors in vascular endothelium cells in ischemic zones possibly participated in regulating the pathophysiological changes of the blood vessels in ischemic zones; The higher expressions of insulin receptors in different cells were possibly one of the self-protective machanisms in which the ischemic tissues confront the anoxemia injury.

脑缺血再灌注大鼠脑组织胰岛素受体基因和蛋白水平表达增加；半暗带区神经元、部分神经胶质细胞及血管内皮细胞等阳染细胞可能参与脑缺血后组织细胞的能量代谢、促新生细胞形成等病理生理调节过程；胰岛素受体在缺血区血管内皮细胞高表达提示其可能在缺血区血管的病理生理变化中起某种调节作用；胰岛素受体在不同细胞中表达增高可能是缺血脑组织对抗缺血缺氧损伤的自身保护机制之一。

At same heights but on different latitude areas, the density of the lower thermosphere is more intense at low latitude than that at high latitude. So does the satellite drag. Therefore, the perigee is lower at low latitude and it is lower by day than at night.

在高度相同情况下，中低纬区热层底部的大气密度比高纬区大，卫星受阻也就更大，从而卫星近地点的高度在中低纬区比高纬区要低、白天比夜间低。

To further verify the rationality and science of the evaluation system and find out its limitation, the thesis takes the northwestern mountainous and hilly towns in Hangzhou for example, chooses evaluation indices, defines weight distribution, assigns values to the indices, constructs the evaluation system, evaluates the land constructability and defines four subareas for the northwestern mountainous and hilly towns in Hangzhou depending on the constructability, which refer to prohibition area, regulation area, constructable area and build-up area.

为了进一步从实践上验证该评价体系的合理性和科学性，以及校验其存在的不足之处，本文以杭州市西北山地丘陵城镇为实例，选择评价指标，进行权重分配和指标赋值，构建评价体系；进行土地适建性评价；界定杭州市西北部山地丘陵城镇的建设适宜度分区——禁建区、限建区、适建区和已建区。

The temperature gradient is larger in case ofussual half-zone model which has a uniform temperature distribution on the hot rod,andmodified half-zone model which has a non-uniform temperature distribution in the hotrod and negative radial temperature gradient near the axis of the hot rod.

模拟半浮区模型提出选择热传导系数与试验液体相当的材料作为热端棒材，使得热端内侧的轴向温度梯度接近于零。模拟半浮区模型的温度分布更接近于全浮区温度分布的一半。对于改型半浮区模型，选择热传导系数高于试验液体值一个数量级的材料作为热端棒材，使得热端温度分布不均匀，并且热端内侧温度高于外侧温度。

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.

结果表明：塑性区和动态静止层的晶粒在热和力作用下发生动态再结晶形成细小的等轴晶，热影响区的晶粒在摩擦热作用下长大变粗；搅拌头旋转速度为2 500 r/min，焊接时间为12 s时，可以获得力学性能较好的焊点，焊点的剪切强度达到9.24 kN；焊点的剪切强度随搅拌头旋转速度的增大而增大，随焊接时间的延长先增大后减小；塑性区的显微硬度较高，但略小于母材，接头显微硬度的最小值分布在热影响区；焊点热输入量较多时，接头为Ⅰ型断裂，焊点的剪切强度较高；焊点热输入量较少时，接头为Ⅱ型断裂，焊点的强度较低。
