It shows that the FE method of tireanalysis under driving state and the method dealing with large slip frictionalcontact problems are correct and reliable. The properties of tires under steady cornering state are studied with FEmethod and experiment. Based on the presented contact solution algorithm, a FEmethod is carried out to analyze the properties of tire under steady corneringstate via imposing slip-rolling-constraints on tire bead nodes which contact therim, and the modules are programmed. The mechanical properties anddeformation of tire under pure steady cornering state and steadycornering-driving state are analyzed, and the results show good agreement withthe experimental data.

ABSTRACT:OBJECTIVETo study the correlation between anatomic structure of the inferior alveolar nerve canal and dental implantation by measuring mandible innervation esemplarsMETHODSThe intramandibular course of mandibular canal and its dimendion were measured in 15 mandibles with teeth; the relationship between blood vessel and nerve was observed in 5 fresh samples in which the artery was filled; and then the data were analyzed by statisticsRESULTSThe mandibular canal was close to the lingual side and the inferior margin of the mandible, the mandibular canal and the 10mm underside of mandible were parallel in the region of the first and the second molars, it runned outboard to genal aperture when it was hereabout genal aperture, and the blood vessel lay above nerve in the mandibular canalCONCLUSIONIn implant operation performed according to normal anatomy, injury to inferior alveolar nerve may be avoided.

［目的］探讨下颌管的解剖结构与牙种植的关系［方法］选取15具牙列完整的成人离体下颌骨标本和5具经过动脉血管内灌注的新鲜标本，测量下颌骨在每个牙位截面上有关牙槽嵴及下颌管的相关数据，进行统计学分析［结果］牙槽嵴顶以及下方10mm宽度由前向后逐渐增宽；牙槽嵴由上向下逐渐增宽；下颌管位于下颌骨体内下方走行中偏舌侧，并近下颌骨下缘，在下颌第1，2磨牙区下颌管走行与下颌下缘成平行状，在近颏孔处转向外和向颊侧出颏孔；下颌管内血管位于下牙槽神经之上［结论］牙种植术中按正常解剖部位并且侧重颊侧骨板操作，可避免损伤下牙槽神经；如果术中下颌管内突然涌出大量新鲜血液，则提示若继续手术可能损伤下牙槽神经。

Methods There were 12 cases, 10 of them were corpse specimens, the other 2 were clinic cases. Firstly we dissociate the contralateral C7 root from the intervertebral foramen to its divisions, secondly we set up a tunnel between the cone and the anterior scalenus, thirdly we moved the C7 root to the gap between the thyroid and the opposite carotid theca through the mentioned tunnel, then we dissociate the injured brachial plexus extensively, lastly we anastomose the contralateral C7 and the injured inferior trunk.

尸解10例，临床应用2例，将健侧颈7神经近端游离至神经根孔，远端游离至前后股处，于前斜角肌后椎体前建立通道，将健侧颈7神经引导至患侧颈血管鞘和甲状腺间隙处，然后患侧行下干、内侧束、尺神经、及正中神经内侧头广泛游离，患侧屈肘屈肩关节后，将健侧颈7神经直接与患侧下干无张力下吻合。

Results: The endoscopic system was slid through the incision and into the subpectoral space after the initial blind dissection in endoscopic-assisted group, and there were problems in 29 breasts of 22 patients (active bleeding in 28 breasts, residual fiber-bands in 25 breasts, hematoma in 13 breasts ), and were dealt with(hemostasis via endoscope, cutting off fiber-bands, clearing hematoma); there was no problem to be dealt with via endoscope, and in other 14 breasts.

两组略做比较，详细描述镜下所见及操作方法。结果内镜组盲剥后导入内镜系统，发现有29侧（分属全部22例患者）存在问题（活动性出血28侧，残余条索25侧，凝血块堆积13侧），进行了相应处理（内镜下止血、切断条索、清除血肿）；其余14侧未发现任何需要内镜下处理的问题。

Fig 1 At the experimental side, two weeks after operation (HE ×100) Many pieces of cartilage cells and spindle-shaped mesenchymal cells were found, by light microscope Fig 2 At the experimental side, twelve weeks after operation (HE ×100) Medullary cavity had formed, which contained hemoblasts and adipocytes, but the trabculae was not typical, by light microscope Fig 3 At the experimental side, twenty-four weeks after operation (HE ×100) The typical cancellous bone had formed, by light microscope Fig 4 At the control side, twenty-four weeks after operation (HE ×100) A large part of CXB was degraded, resorbed and replaced by fibrous tissue, but there was'not any new formed bone, by light mocroscope

Basing on the setup of animal model of root avulsion of the brachial plexus, we divided the experimental animal into four groups by the operative method: Group A: one end of the maternal nerve graft was connected with the upper trunk of the healthy side by end-to-side neurorrhaphy, and the other end was sutured to the distal stump of musculocutaneous nerve infraclevicularly by end-to-end neurorrhaphy. Goup B: on the healthy side, the operation was the same, the other end was sutured to the distal end of C〓 by end-to-end neurorrhaphy on the affected side. Group C: the maternal nerve graft bridged the phrenic nerve and infraclevicular musculocutaneous nerve of the affected side by end-to-end neurorrhaphy. Group D: the phrenic nerve was sutured to the distal end of C〓 supraclevicularly by end-to-end neurorrhaphy.
