消失区

The modification occurred in crystal lattice and the restoration effect of annealing are discussed by analyzing the intensity, width and angle of the X-ray diffraction peaks. The H〓 concentration and related structural information are deduced by the evolution of OH〓 absorption spectra with annealing, which offers the experimental proof for further discussion on annealing. The disappearance of the OH〓 absorption peak at 3300cm〓 after annealing indicates that some H〓 of high concentration diffused further into the substrate and the crystal phase changes accordingly.

根据质子交换波导退火前后在OH〓吸收峰特征的变化，推断波导层H〓浓度及相关的结构信息，并对进一步分析退火机制提供了实验依据；由于3300cm〓〓处的吸收峰代表的是立方钙钛矿的HNbO〓结构成分，因此退火后该峰的消失确实说明高浓度区域的H〓继续向波导深度迁移的事实，同时波导区的晶相成分也发生变化。

Result:After removal of the bilateral lower molars, the remodeling and degenerative activities in different layers of the condyles increased, such as vesiculation of endoplasmic reticulum, distortion of mitochondria and increase of lysosome. Furthermore, the sequential arrangement of collagen fibrils was disturbed, the collagen network broke down and the proteoglycan granules decreased.

结果：细胞发生了不同程度的改建及退行性反应，如粗面内质网的扩张，线粒体肿胀，溶酶体增多等；基质中胶原原纤维的有序排列结构消失，胶原网受到破坏，同时蛋白多糖颗粒减少；基质中脂质小体及基质小囊等成分增多；负重区较非负重区的改变更显著。

N perifocal tissue intracerebral hemorrhage there were rarefaction neuron,cell spaces augmentation,cell diminution,distinct demarcation of cell membrane and surrounding,and we discovered a lot of degeneration and necrosis nerve cells,cell body collapsed,pycnosis anachromasis,nucleoli disappeared. In EPO group we discovered that center area of hemorrhage shinked,nerve cells of degeneration and necrosis decreased in perifocal tissue,majority cells morphous were normal and pathological changes were light.

CH对照组在术后皮层出血中心无神经元，仅见少量胶质细胞，细胞间质空泡样改变；出血边缘区神经元稀疏，细胞间隙增大，细胞缩小，胞膜与周围分界清楚，并可见大量变性及坏死的神经细胞，表现为胞体皱缩，核固缩深染，核仁消失。rhEPO治疗组出血中心区变小，边缘区神经细胞变性坏死减少，多数存活细胞形态相对正常，病变较轻。

Results:The characteristic features included loss of the normal architecture of the portal system and the presence of multiple,sinuous,periportal vascular structures which were enhanced during the portal phase.

结果：主要CT表现为门静脉走行区结构紊乱，正常结构消失；在门静脉走行区出现血管或迂曲、扩张窦隙样血管结构，其在门静脉期明显强化。

It is found that in both the polar cap and the auroral zone a F1 like peak of ionization appeared at 190km height during the main and recovery phases of the storm; while the normal F2 peak disappeared and great depletions of electron density occurred.

发现在磁暴主相和恢复相初期，极光椭圆和极盖区电离层都在大约 1 90km高度出现类似F1的峰，F2主峰完全消失，F区电子密度大幅度下降。

SEM examination showed that the experimental group has regular spongiest structure,complete bone lacuna structure,partial broken os-teone and visible bone canaliculus, while the sham control group has disorderly structure, broken osrteone, little bone lacuna and total invisibility of bone canaliculus.

结果 X线片示A组右侧股骨头骨密度增高，透光区较小，B组骨密度减低，有大小不等透光区；ECT扫描示A组静态放射性分布中等浓聚，而B组静态图像放射性分布呈炸面包圈样改变，欠均匀；组织学检查显示A组骨空陷窝率、血管数、骨髓腔内脂肪细胞直径较B组明显改善(P＜0.01)；扫描电镜检查显示A组松质骨结构较规则，骨陷窝结构完整，部分骨板断裂，骨小管可见。B组结构紊乱不清，骨板断裂，骨陷窝少，骨小管消失。

During the delay interval after the disappearance of Chinese characters and spatial stimulus, P260 and late positive component were generated in centro-frontal areas, N150 and late negative component were elicited in parieto-occipital areas.

在刺激消失后的延迟阶段，汉字任务和空间任务均在头皮前部额区产生P2 6 0和晚期正成分，在头皮后部顶枕区产生N15 0和晚期负成分。

Results All fractures got primary union. In the 4 cases with sciatic nerve injuries, 3 were lower extremities obstinate pain and hyperalgesia and got pain removal in 2 and relief in 1, and 1 was foot-drop and got no improvement. 1 case of saddle area paralysis and urinary and fecal incontinence got improvement after surgery.
