Brownian movement and the hydraulic condition required is only that the coagulant can be dispersed in the water rapidly;As the floc is growing further,the condition of making the floc diameters controlled in a certain limit is to be provided as well as the condition favorable for the collision of the floc.

得到细小粒子的凝集动力由布朗运动决定，此阶段只需要有将混凝剂迅速分散于水中的水力条件；在絮体进一步成长过程中除造成有利于絮体碰撞的水力条件外，还要造成絮体粒径控制在某一限度之内的水力条件，这样可以得到密度高、沉淀效果好的絮体。

Six cadavers were prepared for necroscopy, operative procedure of ILIF were simulated on L3-S1, and all related important anatomic structure and their relationship were observed and record. ILIF with transpedicle screw fixation were also performed with cage insertion.3. Twelve fresh frozen bovine lumbar functional spinal units were prepared for biomechanical testing. According to the different treatment order, the specimens were devided into 7 groups, which included: 1intact specimens, 2specimens were treated by left unilateral facetectomy and had homolateral anatomical threaded cages inserted, 3 TLIF with homolateral pedicle screw fixation, 4 TLIF with bilateral pedicle screw fixation, 5 specimens had anatomical threaded cages inserted on the left by intertransverse process approach, 6 ILIF with homolateral pedicle screw fixation, 7 ILIF with bilateral pedicle screw fixation.

方法1、对20名正常志愿者L3-S1节段进行CT增强+三维重建检查，在三维重建图形上测量横突长度、上下横突间距、椎间孔外椎间隙高度及斜径，观查横突间区域血管走形特点并测量血管内径，然后进行统计分析及评价。2、采用福尔马林固定尸体标本六具，模拟ILIF手术对L3-S1节段进行操作，观察横突间区域重要结构的位置和毗邻关系，并模拟同侧椎弓根钉和单枚椎间融合器的置入过程，探讨该术式存在的问题并改进。3、采用小牛脊柱运动节段标本12具，依序进行不同处理后分为以下7组：⑴正常对照组CG⑵左侧小关节切除+椎间融合器植入组(TLIF⑶TLIF附加同侧椎弓根钉固定组；⑷TLIF附加双侧椎弓根钉固定组；⑸左侧横突间入路椎间融合器植入组ILIF⑹ILIF附加同侧椎弓根钉固定组；⑺ILIF附加双侧椎弓根钉固定组。

The results suggest that cochlear outer hair cells are normal in function with dysfunction of the cochlear nuclei. The main lesion of the disease are neuropath related to stepedius reflex and medial olivo-cochlear efferent nervous system.

此类原因不明的低频听力减退患者听力学表现提示：耳蜗外毛细胞功能正常，与声反射、听传出抑制、ABR波III相关的脑干听觉神经径路为功能障碍的主要部位，可伴有耳蜗或传入神经功能障碍。

Firstly, the soil samples are gathered from the same section such as surface layer soil samples gathered from 0cm to 15cm depth and representation on studied object. Secondly, the precondition of tested samples must be the same. This study indicates that the tested samples must be 1mm diameter, over-dried at 40℃ for 24h and airtight cooling for 24h before measured for air-dry samples, and softly planish the surface at measuring. Lastly, the illuminating condition of light must be the same. This study indicates that the testing geometric condition are light source angle 15°, light source distance 30cm and sensor distance 15cm for soil hyperspectra indoor. The surface of white reference must be the same plane of that of sample.

第一个环节的"相同"是指田间土壤样品采集时的剖面位置一致，如表层土都采集0～15cm深度范围内的土壤，且所采集的样品应能尽量具备研究对象的代表性；第二个环节的"相同"是指土壤制备过程中的一些前处理条件应一致，建议土壤光谱测试样品的粒径1mm，风干土壤样品测试前在40℃恒温条件下烘24小时，然后密闭冷却24小时，测试时土壤表面进行稍稍压平处理；第三个环节的"相同"是保证测试光照条件的一致性，建议在50W卤素灯、8°探头角条件下，采用15°的光源照角度、30cm的光源距离和15cm作为室内士壤高光谱测试几何条件，测试时除遵循光谱测试指南的要求外，还须保证参考板表面与测试土壤样品的表面在同一平面上。

Power of the lathe, and rigid, and a wide range of spindle speed for a strong or high-speed cutting can be turned face, cylindrical, inner hole, as well as the metric system, English, modulus, diametral pitch a variety of threads, and bear the drilling, sets of materials, technology, etc. Boring.

All lesions were 7-12 mm in greatest diameter. Seven cases showed a round radiolucency or a thin clear sclerotic rim in middle or up-outer of femoral neck on X-ray film.

结果：8例股骨颈疝窝均为单侧单发病灶，X线平片仅显示7例，CT均表现为股骨颈前方皮质下类圆形骨质缺损，内为较均匀液体密度，边缘清楚伴有硬化缘，最大径线为7-12 mm.7例在X线平片上表现为股骨颈中轴线或其外上方的类圆形透亮区或硬化环。

The significant linear correlation existed between the dissolution in virtro and the absorption in vivo (P＜0.01). CONCLUSION: The size distribution of FP-GMS was focalizing,and FP-GMS had obviously sustained effect in vitro and in vivo.

本法制备的氟比洛芬明胶微球粒径分布集中，粒径大小符合设计要求，体内外释药结果表明氟比洛芬明胶微球具有明显的缓释作用。

To the gradations with the same maximum nominal grain size,grey correlation was used to analyze the results. The conclusion showed that,except the 9.5 mm-maimum-nominal-grain-size gradation,Jf was influenced mostly by the subtotal triage of coarse aggregates in the third large sieve pore.

对于颗粒最大标称粒径相同的级配，使用灰色关联分析，得出结论：除颗粒最大标称粒径为9.5 mm级配外，Jf受级配中第3大筛孔分计筛余百分率影响最大。
