Measurements for the following anatomical structures were obtained with the aid of a microscope, the distance between mastoid process and transverse process of the atlas, occipital condyle, and superior lateral loop ; the distances between the midline and the v3 at three levels : 1 ) the distal ( dural ) ring ; 2 ) the intersection with the anterior ramus of the c - 2 ; and 3 ) the upper level of the transverse foramen of the atlas ; the diameter of v3h at the origin of the muscular artery and at the sites of penetrating the dural ring ; the width of the v3 at the intersection with the anterior ramus of the c - 2 and at the sites of penetrating the transverse foramen of the atlas
V _ 3h和v _ 3v各有兩個分支： v _ 3h分出肌動脈支和腦膜后動脈支； v _ 3v分出肌動脈支和根肌動脈支，第一、二
脊神經發出的前後支分別與它們又毗鄰關系。通過手術顯微鏡測量下述解剖結構：乳突
尖與環椎橫突
尖、枕髁外側緣、 v _ 3上外側袢的距離；椎動脈v _ 3段在穿硬膜環、與第二頸神經前支交叉、環椎橫突孔上緣三處與中線的距離； v _ 3h在發出肌支處和穿硬膜天渾醫科大學碩士研究主學位論文環處的直徑； v3v在與第二頸神經前支交叉處和穿環椎橫突孔處的直徑。

兩個問題： 1 、劍
脊不直，劍
尖的形制不對； 2 、中正劍應該有血槽。
Only hit your opponent s head, limbs or torso with the sword tip or the edge, not the sides or the spine
只可用鋒口或劍
尖擊打對手的頭四肢及身軀。請勿用刀背或劍
脊部位作攻擊。
Leaders of 13 top mainland medical schools witnessed the launch and exchanged ideas for expediting the medical exchange between the mainland and hong kong in the medical school leaders forum. leading paediatric surgeons and orthopaedists from hong kong, the mainland and overseas also convened at the advances in paediatric surgery and paediatric orthopaedic surgery symposium held on the same day to discuss various important issues such as spina bifida, scoliosis, trauma care, limb realignment and paediatric minimally invasive surgery
十三間內地頂
尖級醫學院校的領導應邀出席成立典禮，並參加醫學院領導交流會，就拓展香港與內地醫學交流，集思廣益。同日舉行的還有小兒外科及小兒骨科新進展學術研討會，參加者包括海外、本港及內地的傑出小兒外科及小兒骨科專家，探討課題包括
脊柱裂、
脊柱側彎、創傷處理、肢體矯正、小兒微創外科等。
In short, the analysis of arc - tip fracture shows that : the initiation of void - mode fracture can be judged by vgc criterion, or by j ". according to sx criterion ; fracture direction of void - mode fracture can be determined by ctod and peak value line of stress triaxiality. the mesomechanics mechanism of shear - mode fracture need further study, and analysis found direction of plastic belt is consistent with the direction of shear - mode fracture
綜上所述，本文通過對圓弧
尖端裂紋的分析表明：對于韌窩型斷裂的起裂，可以依據-復合型斷裂的sx準則按照i ~ 1來預測起裂載荷，也可用v _ （ gc ）判據來預測起裂載荷，二者結果相近；對于韌窩型斷裂的斷裂角，用ctod矢量方向和三軸度
脊線方向判斷均和試驗結果基本。
In general, point and curve primitives are able to provide sharp corners and ridge features ; sphere primitives are able to achieve smoothing effects and provide semi - sharp features ; and cube primitives are able to handle sharp corners, sharp edges and flat faces with the corners, edges and faces of the cubes respectively
點和曲線編輯工具可以用來獲取

The thesis studied the change of stress triaxiality in the four - point curved beam made in 16mnr with arc - tip crack and its important effect. in the beam, the points of peak value of stress triaxiality distribute along a line, whose direction is well consistent with the fracture direction got by experiment when so > 3mm
在圓弧裂紋試件中，裂
尖附近的三軸度較高的點呈
脊線分佈，按照
脊線分佈擬合計算得到的三軸度
脊線夾角在偏心距so 3mm時與試驗測得的斷裂角符合較好，這種情況下試件發生的是韌窩型斷裂。
Vp2 from tsim sha tsui towards central is illustrated as an example. taking into account the committed planned developments redevelopments known at this stage, some parts of the ridgelines have already been breached by existing high - rise developments
上圖的例子顯示出從尖沙咀的瞭望點二遠眺中環的情況。從既定計劃中的發展重建項目在現階段已知的發展情況看來，一些高聳的發展已超逾部分山脊線的高度。
