Results (1) Osteitis and destruction of end-plate showed long T1 and long T2.(2) Anterior and lateral abscess had long T1 and long T2 presenting even and structure-less signal.(3) The intervertebral discs showed normal or only degeneration at the early stage, and destroyed at later stage.(4) With Gd-DTPA enhancement, fibrotic granulation around abscess and destroyed area was well demonstrated.(5) Abscess in the bone and/or paraspinal abscess, destruction of end-plate were the important evidence for early diagnosis.

结果 (1)椎体骨炎及终板破坏呈长T1长T2信号，(2)椎旁或椎前冷脓肿呈长T1长T2均匀无结构信号，且上下跨越范围较大，(3)早期椎间盘信号正常或只出现退变，晚期则被破坏，(4)Gd-DTPA增强扫描可清楚显示冷脓肿周围纤维肉芽组织及椎管内侵犯，(5)骨内小脓肿和/或椎旁脓肿、椎体终板破坏是MRI诊断早期脊柱结核的重要依据。

RESULTS: Sixteen weeks later, the CR tablets showed that in the normal group, joint space was normal, and the articular facet was complete and smooth with no osteophyte; in the model group, the medial space was obviously narrowing with obvious osteophyte.

结果：干预16周后，CR片显示正常对照组关节间隙正常，关节面平整光滑，无骨赘；模型对照组内侧间隙明显变窄，有明显骨赘。

pressure or sound sensitive vertigo seemed to occur when there were abnormal communication between the inner ear and surrounding structures or the shortend distance between the footplate and saccule.

上半规管裂时内耳和周围结构之间存在异常交通，膜迷路积水和镫骨足板活动过度则可能系球囊与镫骨足板之间的距离变近，可出现对声音或压力敏感性眩晕。vemp阈值的变化可以对这类眩晕进行客观评价。

Each implant was embedded in bone block: 23.4mm in height, 25.6mm in mesiodital length, 9mm in buccolingual width with cortical thickness of 1.3mm.

所有的植入体皆为长11mm、宽4mm，螺纹为0.5x0.5mm，以减少变因。每根植体假设种植在高23.4mm、远近心侧宽25.6mm、颊舌侧厚9mm的颚骨区块中，皮质骨厚度皆设为1.3mm。

Osteoarthritisis a non-specific inflammation which is mainly characterized by the changes in the cartilage; it could result in subchondral bone necrosis,cystis degeneration,bone mineral densityincrease and the osteophyte formation.

骨关节炎是以软骨改变为主要特征，进而造成软骨下骨坏死、囊性变、骨密度增加和伴发骨赘形成的一种非特异性炎症。

Results:Subperiosteal bone absorption,in addition to generalized osteoporosis was of characteristic,and fibrocystic ostitis and ground glass appearance of cranium were also of great importance for diagnosis of hyperparathyroidism.

结果：甲旁亢除引起全身骨质稀疏外，认为骨膜下骨质吸收为特征性征象，纤维囊样骨炎和颅盖骨磨砂玻璃样变对诊断有重要价值。

Undermining bone resorption and hyalinization of PDL also took place during tooth rotation.

在牙齿的扭转过程中，PDL的透明性变和牙槽骨的潜掘性骨吸收也表现出来。

Non-occluding teeth with a hypofunctional periodontium have a lower rate of bone remodeling, and are more susceptible to the injury in periodontal tissues caused by orthodontic force than normally occluding teeth, such as hyalinization or undermining bone resorption, even dentin resorption.

正畸治疗中，无咬合接触的牙周膜废用性萎缩牙较正常咬合接触牙对矫治力反应差，骨改建率低，易发生玻璃样变和潜掘性骨吸收，延缓牙移动，因此对无咬合接触牙的临床治疗中应采用轻力。

X-ray examination demonstrated that at 4 weeks after implantation, some or even lateral intertransverse bridging regions were unclear, and material density in the repairing group was lower than control group; at 8 weeks after implantation, interspace between up and down bridging was shrunk, and a great quantity of calluses were successively formed; at 12 weeks after implantation, complete confluence was observed, and the density in the repairing group was closed to that in the control group.

结果：采用脱蛋白处理后的松质骨可见大小不等、相互交通、开放孔隙的网架结构，孔径200~500 μm，孔隙率60%左右，其无机成分为羟基磷灰石，有机成分为胶原，力学性能保存良好，细胞相容性良好。X射线片结果显示：植入第4周，横突桥接处部分区域模糊，以内侧明显，此时修复组材料密度略低于对照组；第8周上下桥接部间隙变小，大量连续骨痂生成；12周后完全融合，两组材料密度接近。

Upper central incisors moved forward and downward together with maxillary, at the same time they upright in the sagittal plane and tip mesially. 3 The occlusion plane rotated clockwise for about 1.5°. 4 The width increasement effect of RME comes from approximately the equal amounts of skeletal and dental expansion. The mode of dental movement was a combination of body and tipping movements of posterior teeth.

结果：1后牙在宽度方向上为整体移动和倾斜移动相结合的移动方式，但第一磨牙和第一双尖牙稍有差别；牙齿和骨对宽度增加的贡献各占约1/2；2后牙在垂直方向有伸长的趋势；3第一磨牙和第一双尖牙均向前整体移动，轴倾度保持不变；4中切牙整体随上颌骨前部向前向下移动，其牙长轴发生直立，轴倾度增加；5上颌平面发生顺时针旋转。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
