零部件表面电弧喷涂研究 - Methods ： fifty paired embalmed cadaveric humeri ( twenty - five pairs : fourteen from male donors and eleven from female donors ) were scanned in medial - lateral ( ml ) and anterior - posterior ( ap ) position according to the humeral retroversion by ct . images of the humeri in the transverse planes at the lowest border of neck ( lbn ) , 20mm and 40mm distal of lbn ( lbn - 20 、 lbn - 40 ) , isthmus , head - neck anterior - posterior ( hn - ap ) were obtained . sixty - one extracortical and intracortical parameters were measured exactly by image analytic computer software that included offset , head position , head - shaft angle , head to tuberosity height ( ht ) , head thickness , curvature radius , articular surface arc ( sa ) , neck diameter , isthmus position , proximal and distal border of isthmus , maximum coronal and sagittal diameter of medullary canal and thickness of cortical bone in four planes , including lbn , lbn - 20 , lbn - 40 and isthmus
方法： 50根成对防腐肱骨(男14对，女11对)按肱骨头扭转角置于冠状位和矢状位，行肱骨全长，头颈矢状面，解剖颈下缘及其下20mm 、 40mm ，髓腔狭窄部四平面ct扫描，由ct软件测量冠、矢状位髓腔内外参数共61项，包括头心?干轴距，头位置，头干角，头?结节高度差，头厚度，头半径，关节面张角，解剖颈直径，髓腔狭窄部位置，解剖颈下缘及其下20mm 、 40mm和狭窄部四个平面髓腔的最大冠、矢状径，皮质骨厚度等。 - The function of stone artistic splice complete through to established basic design or source material warehouse with the help of others graph process software . besides author come up with a new program or machine method in accordance with stagger in the thicknes and vertical length at the stone sticking execution , i . e ensure the accuracy in measurement to approach subsection by space spiral line , the data used directly by numerical control machine . finally machined the stone become a spiral line columned surface arc slab
此外，针对旋转楼梯扶手石材贴片施工时所出现的厚度和垂直方向易产生较大错边的问题，提出了一种新的建模方案和加工措施，即在保证测量精度的基础上，分段以空间螺旋线逼近，经过计算机处理后的参数直接可供数控加工使用，最后把石材贴片加工成螺旋线型的柱面弧形扳。
