腔形成

Art of figuration of the protruding after classics skin centrum (Percutaneous Kyphoplas-ty, PKP) is to be in art of figuration of classics skin centrum (Percutaneous Ver-tebroplasty, the technology of small innovation of surgery of a rachis that the development on the foundation of PVP) rises, its fundamental is the buy inside preexistence centrum enters but expansile ball bursa , the dilate that carries ball bag forms a cavity inside centrum, again infuse stuff stuff, correct deformation thereby, achieve constrictive to a few osteoporosis or tumour centrum that bring about fracture (Vertebral Compressionfractures, the remedial purpose of VCFs).

梗概： 经皮椎体后凸成形术(percutaneous kyphoplas-ty，PKP)是在经皮椎体成形术(percutaneous ver-tebroplasty，PVP)的基础上发展起来的一项脊柱外科微创新技术，其基本原理是先在椎体内置入一个可膨胀性球囊(inflatable bone tamp，IBT)，通过球囊的扩张在椎体内形成一个空腔，再注入填充材料，从而纠正畸形，达到对一些骨质疏松或肿瘤等导致的椎体压缩性骨折(vertebral compressionfractures，VCFs)的治疗目的。

The embryonic vessels failed to invade into the labyrinthine layer of placenta, which impaired the embryonic-maternal vascular connection. These defects could not be rescued by wild-type tetraploid blastocysts, excluding the possibility that they were due to the extraembryonic tissues.

组织免疫组化分析结果显示：毛细血管腔异常扩张，排列紊乱，不能形成大血管及细致有序的血管网络；胚外中胚层来源的卵黄囊脏层扁平上皮细胞形态变圆，与内皮细胞连接受损；胚胎血管不能侵入胎盘迷路层，胚体与母体血管连接受损。

Results: Current of 1 mA, 210 s could cause necrosis and cavitation in the dorsal funiculus, resulting in bilateral corticospinal tract injury; rats with electrolytic lesions exhibited declined motor function with decreased Tarlov score, increased Ashworth score and reduced inclined plane angle, the HRP labeled neuron counts in motor cortex were also significantly lower in the lesioned group than sham-operation group.

结果：1 mA， 210 s的损伤电流，可在脊髓后索造成神经组织坏死，形成空腔，使双侧皮质脊髓束纤维受损；术后1周、2周、3周观察，电损毁组大鼠运动功能显著低于假手术组，表现为后肢运动评分下降，Ashworth 肌张力评分增大，斜板实验角度下降；电损毁组运动皮质标记神经元计数也显著低于假手术组。

Under transmission electron microscope, cellular swelling in brain tissue, nuclear membrane of neuron has incisures, some chromatic agglutination, group A mainly appears endoplasmic reticulum distention and glial cell endocytosis, while group B mainly appears histolysis; cardiac fibrous structure is chaotic, Z line concentrates, mitochondria swelling, nucleus deform; the ecphyma of podocyte becomes thinner and longer like villus, some mix together, plasma membrane infolding of renal cells decreases, mitochondria malformation, cells in lumens.

透射电镜观察显示，试验组动物脑组织细胞肿胀，神经元核膜出现切迹，部分染色质凝集，A组动物出现内质网扩张及胶质细胞吞噬现象，B组动物以组织溶解为主；心肌纤维结构紊乱，Z线聚集，收缩带形成，线粒体肿胀，核变形；肾小球足突细长，绒毛化，并可见足突融合，肾小管上皮细胞质膜内褶减少，线粒体畸形，管腔可见脱落细胞，上述改变均以B组为著。

Interior surface of laser tube, reducing the effect of heat abatement

变质的水会形成水垢附着在激光管腔内，影响激光器的散热效

Result The HRCT appearances of EAA inciuded micronodules or nodules were seen in 8 cases,space consolidation in ten cases,ground-glass opacity in eight case, limited pulmonary emphysema in one case,four cases had air trapping and mosaic perfusion ,thick interlobular speta and honey combing in eight cases.

结果 外源性过敏性肺泡炎HRCT主要表现为微结节或结节8例，气腔实变10例，磨玻璃样变8例，局限性的空气残留并形成"马赛克"样灌注4例，局限性肺气肿1例，小叶间隔增厚及蜂窝状改变4例。

The rise of Hcy in plasma is a risk factor for cerebral thrombosis and lacunar infarction.

血浆Hcy水平升高是脑血栓形成及腔隙性脑梗死的危险因素。

Because it means there is about 5 cm length catheter left in the epidural space and it increases the loop and knot formation.

因为这表示有五公分长度的导管留置於硬膜外腔，而这会增加导管绕圈和打结的形成。

The structural design and mechanical analysis method of sealing system of high pressure liquid spring are discussed in this paper.

通过对高压密封腔内轴-密封环形成的密封间隙内液体泄漏量和压力分布进行计算与理论分析，探讨高压液体弹簧密封系统的结构设计和力学分析方法。

At this point the impeller wheel and the water loop to form a crescent-shaped space between, and this space has been divided into the impeller and leaves an equal number of a number of small cavities.

此时叶轮轮毂与水环之间形成一个月牙形空间，而这一空间又被叶轮分成和叶片数目相等的若干个小腔。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
