The dispersion of particles are also related to the interactionbetween nanosilver and polymer. Nanosilver dispersed well in PS, while form larger branchedclusters in PMMA, and polymers could prevent nanoparticles from aggregation. The interaction between nanosilver and polymers depends on the properties of polymers and treatment. XPS results indicated that no obvious interaction between nanosilver and PS was foundbefore and after heat treatment; for AS matrix, there exists a interaction between nanosilver and AN,moreover AN on the nanosilver surface could cyclize and lose N after heat treatment at 150℃ for1h; for PMMA matrix, there exists a interaction between nanosilver and O atoms, heat treatment at150℃ for 1h could lead to the reaction between Ag, S and O in the interlayer of composite andchange the interface interaction.

纳米银粒子的加入改变了聚合物体系对激光能量的吸收和转换方式，导致其激光离解方式的变化，通常此种粒子会促进聚合物的炭化，且在界面可能有诱导石墨化的作用；而银粒子自身的离解及其对基体激光离解的作用都受两相的界面相互作用的影响，即与聚合物基体的性质、后处理等有关，热处理后两相界面的变化对PS和AS体系的炭化影响不大，但PS体系中银团簇的最大原子聚集数减小；而对PMMA体系则基本上消除了激光炭化。

Results: Remarkable pathological changes were found in h ippocampus: Nissl bodies decreased or disappeared, cyton swelled.

This system mainly contains the front-end pulse interception and back-end software analysis. In the first part, we used a non-invasive infrared measurement method based on the dual channel simultaneous measurement technique. We measured the photo-plethysmograph from the subject's fingers and toes simultaneously, then used an analog circuit and central control unit to process the signals. Finally, the digital volume pulse data is processed by a personal computer. Because the characteristic points of digital volume pulse always occur in sharp variations, this paper proposes two algorithms to solve this problem. First, we find the pacemaker and percussion wave peak from transient slope variation, and then locate the dicrotic notch and dicrotic wave peak by using the wavelet transformation algorithm. When we analyze the data, we use the Visual Basic graphical user interface, which together with the Matlab is the core of the system.

本系统主要包含前端脉波撷取及后端软体分析两部分，其中前端脉波撷取部份是以非侵入式的红外线量测方式，双通道同步量测受测者手指与脚趾的光容积变化描记图，同时将此讯号经类比处理电路及中央控制单元输出成为数位容积波，再传送至个人电脑中；而在后端软体分析部份，因数位容积波之特徵点皆出现於波形中急剧变化的部份，故本论文以瞬间斜率变化量来定位脉波讯号中的起搏点及主波峰顶点，并利用小波转换演算法（wavelet transformation algorithm）来分析重搏切迹与重搏波顶点；程式撰写主要以Matlab为核心，结合Visual Basic的图形化使用者操作介面，增加系统与使用者间的亲和力。

E. , ACTH antagonizes the analgesia mediated byμand δ opioid receptors, but notκreceptor;(2) The antagonizing effect of ACTH on opioid analgesia is proposed to be mediated by ACTH receptors, although the latter has not been characterized;(3) A contradictory interaction on intracellular cAMP content may constitute one of the postreceptor mechanisms underlying ACTH antagonism of opioid analgesia;(4) Another proposed mechanism of the anti-opioid effect of ACTH is that ACTH can modulate opioid-induced suppression of calcium influx;(5) ACTH has been shown to induce Fos protein expression in selected areas of the rat brain including the nuclei involved in pain regulation as well as the ependyma of the third ventricle and the aqueduct.

根据以上实验结果，本论文首次提出以下论点：（1）ACTH在脊髓水平对抗阿片镇痛具有受体选择性，即ACTH可对抗μ受体和δ受体介导的镇痛，不对抗κ受体所介导的镇痛；（2）由于ACTH与阿片μ受体的肽类配体的结合位点仅有很低的亲和力，与μ受体的非肽类配体的结合位点以及δ受体无亲和力，推测ACTH是通过中枢内的ACTH受体介导发挥抗阿片效应的；（3）ACTH抗阿片作用的受体后作用机制之一是在cAMP信使通路水平与阿片发生相互作用；（4）ACTH抗阿片作用的另一受体后机制是在〓水平影响阿片的效应；（5）通过Fos蛋白的诱导揭示：ACTH可以作用于脑内多个核团，其中包括许多与痛觉调制有关的核团，推测ACTH可能通过激活这些核团的神经元而发挥其中枢效应。

The Solidification temperature range was defined as 110-200℃ by DSC analysis. More accelerant used can increase the casing samples dynamic performance, but more than enough accelerant can induce a severe solidified reaction that result in a smaller polymeric meshwork and reducing the sample's performance. Normally the Accelerant dosage can be 2 portions; The Epoxy resin CFRP has a obvious better performances than the Vinyl-ester Resin CFRP, i.e. had a Bend Strength of 1516MPa, LSS of 85MPa, also Tg raised to 195~C~ When used the end-carboxyl polyether to reinforce the epoxy resin, the casing sample's SS, BS and Crack Elongation all increased geminately. The CFRP performance also increased a little, that is because the performance of the CFRP mainly contributed by the CF. The reinforced resin improved the interface between the CF and resin that contribute to the little increasing.

通过DSC分析确定了该环氧树脂的固化温度范围为110~200℃，促进剂增加会提高浇注体力学性能，但过多的促进剂会使固化反应剧烈，聚合网络减小，使浇注体性能下降，一般用量为2份左右；以环氧树脂为基体的复合材料性能明显比以乙烯基酯树脂的性能提高，弯曲强度达到1516MPa，层间剪切强度达到85MPa，同时Tg也上升到195℃；用端羧基聚醚增韧环氧树脂后，其浇注体的拉伸强度、弯曲强度及断裂伸长都成倍增加，复合材料的性能也有所提高，但提高幅度不大，因为复合材料的力学性能主要由碳纤维承担，树脂增韧后改善了复合材料的界面性能。

From 2004 to 2007, 34 cases were treated with extrapedicular screw fixation in Department of Orthopaedics, Third Affiliated Hospital of Sun Yat-sen University. The screw entry point, angle, depth and diameter were measured and defined on the thoracic vertebrae pedicle by CT thin-slice scan in standard prone for all cases before operation. The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement.

Defining bone organization threshold, withdrawing each outline, partitioning each edge of layer picture, edited selectively and repaired by hole processing. After a redundancy data was cleaned, the thoracolumbar 3-D finite element geometry model was acquired. Then area mesh could be kept as the document Ansys named .lis as the suffix and be introduced into Ansys software directly to mesh body, and then transferred the body mesh to mimics to assignment son the basis of CT values, once again import Ansys to establish 3-D finite element model.

After HRP application, HRP labelled cells were distributed in the nucleus of trapezoid body , lateroventral periolivary nucleus , retrotrapezoid nucleus , lateral paragigantocellular nucleus and lateral reticular nucleus . The findings demonstrated the existence of neural structural relations between the chemosensitve areas and the Tz, LVPO, NRT, LPGi and LRt, and revealed that these nuclei might participate in the mechanism of central chemical regulation on respiration.

观察到用浸有HRP的滤纸局部敷贴于延髓腹外侧表面化学感受区后，在延髓斜方体核、外周橄榄腹外侧核、斜方体后核、巨细胞旁外侧核和外侧网状核等核团找到HRP标记的细胞，表明上述延髓内部核团与腹外侧表面化学感受区之间存在神经结构联系，提示延髓腹外侧表面化学感受区对H〓等物质的化学感受机制可能与上述核团神经元伸向该区的突起有关。

By analyzing in detail the structural evolutionary history, from Mesozoic to Cenozoic, of different rift belts in western, northern, central and eastern Africa, the authors think that the Mellit area was on the northwestern shoulder of the South Sudan Rift. The rotation of the Mellit block toward northwest was the outward rotation of the northwestern shoulder of the South Sudan Rift during the rifting phase, and the rotation toward southeast was the inward rotation of the rift shoulder during the post-rift thermal sag episode.

经过详细分析非洲大陆西部、北部、中部和东部中新生代裂谷带的构造演化史后发现：Mellit地块实际上位于南苏丹裂谷带的西北裂谷肩上，该地块自晚白垩世初期至中新世初期，向NW方向倾斜是南苏丹裂谷带于裂谷化阶段造成的裂谷肩块体的向外旋转；该地块自中新世以来向SE方向倾斜是南苏丹裂谷带在后裂谷热沉降阶段造成的裂谷肩块体的向内旋转。
