In the part 3 of the thesis, we develep the animal model using the method of part 2 of the thesis. 6weeks later, Clearance of focal lesion in necrosis femoral head is performed. Cancellous bone adding rhBMP〓 is implanted in the space after sequestrum cleaning. Imagical、morphology and biomechanics study show its result is superior to traditional cancellous bone grafting.

因此，在论文的第三部分，我们首先按照本论文的第二部分的方法，制作股骨头坏死的动物模型，6周后，行坏死股骨头病灶清除术，分别采用将松质骨、〓+松质骨屑植入死骨清除后空腔内，通过影像学、形态学及生物力学研究显示，〓+松质骨组的成骨速度及质量优于传统的松质骨移植。

Accumulation of serous fluid in one or both pleural cavities.

积脓体内积有脓液，尤指在胸膜腔内

It was filled with pale yellow serous fluid in only a single cavity.

卵巢黏液性囊腺瘤腔内充满了黏液性物质且通常可见多个囊肿。

Dynamic imaging of these fractures has demonstrated significant mobility at the fracture site and emphasized their abundance in the thoracolumbar junction, which is subjected to high stresses.3,4,19,22 Analysis of the serous fluid in the cavity showed a consistency similar to synovial fluid.20,21 Other researchers also reported a serous/serosanguineous fluid consistency similar to plasma.16,30 Biopsies of the cavity lining demonstrated fibrocartilage within a fibrous stroma, representing a pseudosynovium of a nonunion.20,21 Stallenberg et al,32 prompted by the reports of gas in vertebral pseudarthrosis, reported the presence of air in pseudarthroses of various bones in the appendicular skeleton in a rate of 70%, detected with computed tomography-scanning through the site of nonunion.32

这些骨折患者的动态影像显示在在骨折部位有明显的活动度，胸腰段承受高应力尤为明显[3，4，19，22]。对腔内的浆液分析显示类似滑膜液[20，21]，其他研究人员还报告说浆液/血清样的液体与血浆类似[16，30]。椎体内气体现象中假关节的出现促使Stallenberg等[32]对不愈合四肢骨进行CT扫描，发现有70％的有气体存在。

If the liquid in the diaphragm cavity to promote too little to promote liquid, the magnet will move to the ZSL trigger, the trigger output of a pulse signal to the PLC control box.

如果在 隔膜泵推进液腔内推进液太少，磁体将移动到触发器ZSL 处，触发器输出一个脉冲信号到PLC 控制箱。

The interactions between the two streams of flow undoubtedly have an influence on the morphology of the solid state.

在这一过程中熔体的流动，尤其是在型腔内的流动影响着高分子材料的凝聚态结构。

Objective To explore the clinical features of the disease of isolated sphenoid sinus and improve the abil-ity of diagnosis and treatment.

孤立性蝶窦病变是指原发于蝶窦并且局限于蝶窦腔内的疾病，没有侵犯周围的比邻结构。

Experimental TEA CO2 laser with printed circuit board preionization is used. The laser has gain length of 90 cm. The resonator is composed of a total-reflective concave spherical mirror of curvature radius 20 m and a total-reflective plane mirror of mirror radius 4.5 mm, separated by 5 m distance.

实验中TEA CO2激光器采用印刷电路板预电离结构，增益长度90 cm，腔长5 m，球面全反射镜曲率半径20 m，输出端平面镜半径4.5 mm，得到了内环半径为4.5 mm、外环半径为5.5 mm的基模环形光斑输出。

It is made clear through the theoretic analysis that this phenomenon is caused by stimulated emission and interband carrier absorption that depend on the longitudinal mode competition, thermal effects, and so on.

理论分析表明这是由于激活区内载流子消耗、带间载流子吸收综合作用的结果，而这些效应与腔内的模式选择、注入电流产生的热效应等过程有关。

Methods 182 cases of ureteral stricture treated by endourological technique from 1992 to 1997 were reviewed.

对182例采用腔内泌尿外科技术治疗的输尿管狭窄病人资料进行回顾性分析。

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。
