The periostea of both experimental and control side of the mandibular ramus were taken and prepared, 2 of each 5 rabbits in a group were prepared for HE stain detection and 3 for proliferating cell nuclear antigen immunohistochemical detection.Results:1, The newly formed bone was detected on the lateral aspect of mandibular ramus after periosteal distraction. The bone was shaped like a hill. It looked very low and was full of holes at postoperative day 28. With the time of consolidation period lengthened, the newly formed bone matured gradually. X-ray examination showed the new bone shaped like a hill. The average values of new bone height at postoperative days 28,35,42 and 56 were 1.86 + 0.15mm, 2.29 + 0.29mm,3.19 + 0.13mm and 4.70 + 0.45mm. Histological examination of both HE stain and picricacid-fuchsin stain showed the increase in the number of osteoblasts and the change in the orientation of collagen fibers and bone trabecula. There were no significant differences between newly formed bone and original bone on the lateral aspect of mandibular ramus at postoperative day 56 histologically.2 Compared with the control side, the distracted periostea proliferated obviously under the microscope, and the number of periostealcells increased with satiation of cellular nuclear per unit area. The images of PCNA immunohistochemical stain of periosteum showed that the experimental periosteum proliferated obviously after distraction compared with the control side.

结果：骨膜牵张成骨的实验研究南京医科大学硕{学位论文l、骨膜牵张后，可见下领升支外侧的骨皮质上有新骨形成，新骨呈山峰状凸起，术后第28天的新生骨较低平，多孔隙，随着固定时间的延长，新骨逐渐成熟；下领升支前后向切线位X线投照显示新骨呈山峰样隆起；经测量，术后第28、35、42和56天组平均新生骨厚度分别为x.86士0.15mm、2.29士0.29mm、3.19士0.13mm和4.70 土0.45mm；脱钙骨组织的HE染色和不脱钙骨组织的苦味酸一品红染色的组织学观察均显示了新生骨在成骨细胞数量上的增长，以及胶原纤维和骨小梁排列方向上的变化，术后第56天的新生骨在组织学上与原升支骨组织已无明显区别。2、HE染色显示，与对照组相比较，实验侧骨膜增生明显，细胞间排列紧密，单位面积内骨膜细胞数增多，细胞核饱满；骨膜PCNA 免疫组化染色显示，与对照侧相比较，实验侧骨膜在牵张后出现了明显的增生迹象，PCNA阳性细胞分布紧密，单位面积内阳性细胞数较对照组多，靠近骨表面的骨膜中的阳性细胞数更多而且分布更为紧密。

At the same time, the intensity ratio of the ICT fluorescence to the LE fluorescence, I〓/I〓, shows a "bell"-shaped variation with increasing CTAB concentration The intensity ratio was found to level off after the CMC of CTAB Together with the data from UV-Vis absorption spectroscopy, electric conductance measurements and the control experiments with tetramethylammonium bromide, it was concluded that the"bell"-shaped variation in the intensity ratio before CMC is due to the formation of premicelle aggregates consisting of ICT fluorophore and CTAB.

此时，ICT荧光强度与LE荧光强度之比，I〓/I〓随CTAB浓度增大而呈&钟形&变化。当CTAB浓度高于CMC时，I〓/I〓为一常数。根据紫外-可见吸收光谱，电导以及四甲基溴化铵对照实验的结果可知，当CTAB浓度低于其CMC时，I〓/I〓的&钟形&变化是由于长链对二烷基氨基苯甲酸与CTAB组成的胶束前簇集体形成所致。

It is widely employed in many industrial domains. The most attractive domain of ring rolling technology is to roll the rings with specially-shaped cross section directly. But the rolling deformation law of ring with specially-shaped cross section is more complicated compared with rectangle section ring and in the process there are lots of special phenomenon such as underfilling, shrinking-drawing, concave, saucer shape and etc.

环件轧制技术最有吸引力的领域和发展方向是直接轧制成形截面轮廓复杂的异形截面环件，然而，与矩形截面环件相比，异形截面环件轧制成形规律更复杂，轧制过程中常常出现截面轮廓充不满、拉缩、凹坑、碟形等各种特有现象，这些现象是异形截面环件轧制成形规律的客观反映。
