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根成對防腐肱骨（男14對，女11對）按肱骨頭扭轉角置於冠狀位和矢狀位，行肱骨全長，頭頸矢狀面，解剖頸下緣及其下20mm 、 40mm ，髓腔狹窄部四平面ct掃描，由ct軟體測量冠、矢狀位髓腔內外參數共61項，包括頭心?干軸距，頭位置，頭干角，頭?結節高度差，頭厚度，頭半徑，關節面張角，解剖頸直徑，髓腔狹窄部位置，解剖頸下緣及其下20mm 、 40mm和狹窄部四個平面髓腔的最大冠、矢狀徑，皮質骨厚度等。For correcting of facial esthetics and severe skeletal discrepancies, the patient was treated orthodontically with edgewise appliances and surgically with mandibular bilateral sagittal split and inferior border osteotomies
為了達成改善顏面外觀與嚴重顎骨異常的問題，此患者接受角線裝置與下顎骨雙側矢狀劈開截骨術與下顎下緣截骨術。In this paper, the concepts, the historical background, the importance and current application of scientific computing and visualization of scientific computing are introduced and the visualization of computational detonation mechanics is specially expounded. based on the sumarization of the visualization software visc2d and visc3d directing at the mmic ( multi _ material in cell ), the key point of the improvement and the research contents are listed. based on the basic visualization reference model and the data file format of mmic, the file format of vector data is defined. the 2 - d data field visualization technology is described in detail. include the visualization of scalar field and vector field. the weak points of the visc2d software is overcome, and we propose the full - frame coloring mapping method and the visualization of the vector data using the clic ( coloring _ noise line integral convolution ). in addition, the method to draw and display shock wave by edge probing operator is introduced. in the design of the program, in order to overcome the shortcoming of visc2d with sdi ( single document interface ), the software vsv ( visualization of scalar and vector ) with mdi ( multi document interface ) is designed. compared with visc2d, the advantage of vsv includes : ( l ) vsv is a mdi applied software which can be used to view various kind of data, ( 2 ) vsv resolves the flash during displaying moving images which are produed by full - frame coloring method used to the visualization of scalar fields, and ( 3 ) vsv can be used to visualize vector field such as velocity. at last, the visualization of the output data from mmic in explosion and shock is realized by vsv
首先簡要介紹了科學計算與科學計算可視化的概念、歷史背景、意義及應用現狀，重點說明了計算爆炸力學中的可視化問題，在總結多流體網格程序mmic的可視化軟體visc2d和visc3d的基礎上提出了改進要點和本文的研究內容。在介紹可視化基本參考模型和mmic程序的數據文件結構的基礎上，給出了矢量數據文件的結構，詳細闡述了二維數據場的可視化技術，包括標量場和矢量場的可視化，針對原visc2d軟體的不足，給出了改進方法，提出了全幀著色映射方法和用於矢量數據可視化的基於噪聲著色的線積分卷積方法，以及提出了利用邊緣檢測運算元提取和顯示沖擊波的方法。在程序設計上，針對原visc2d軟體只適用於單文檔窗口的缺點，本文利用多文檔mdi窗口，研製了標量場與矢量場的可視化軟體vsv （ visualizationofscalarandvector ） 。
