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。

Remove the internal circuit boards, mechanical parts struck the mouse circuit board and connected to the Agency's long-tongued, take down the mechanical parts.

取下内部电路板，拨动鼠标机械部分与电路板联接处的长舌，取下机械部分。

Tiger tongue is red can watch Xie Youneng to admire already if really, the overgrow of leaf two sides of amaranth downy, below sunshine, it is dazzling more below lamplight in the late evening particularly.

虎舌红既能观叶又能赏果，紫红色的叶子两面长满了绒毛，在阳光下，非凡在晚上灯光下更是刺眼。

Carton packaging machinery can be divided into origami, the next paper, board push drugs, open the carton, carton transmission, folding tongue, the tongue inserted, to fight mild pressure batch functions.

纸盒包装机械可分为折纸、下纸、药板推送、纸盒打开、纸盒传输、折舌、插舌、压平和打批号等功能。

Affected anatomic sites included: submaxillary and submentum (7), maxilla(7), palate(6), salivary gland(5),root of tongue(5), neck(4), cheek(2), gingival(1). All of the cases are NHL, B cell lymphoma 27 (72.97%), T/NK cell lymphoma9 (24.32%), one cases cell origin was uncerten.

发病部位依次为颌下、颏下7例、上颌部7例，腭部6例，腮腺5例，舌根部5例，颈上部4例，颊部2例，牙龈1例。37例全部是NHL，B细胞淋巴瘤27例(72.97％)，T／NK细胞淋巴瘤9例(24.32％)，1例未确定细胞来源。

The pressure fluctuations were measured at different positions along the axial direction on the tonge. The coherence analysis was utilized for illustrating the blade passing frequency cancellation mechanism. A 3-D flow visualization method, which overcame the blind slight from LDV and PTV, was used to present the differences of internal flow patterns.

实验中分别进行0度、5度与10度三种叶轮扭转角之设计，在横流扇出风口以声学人偶进行噪音量测，评估不同叶轮扭转角在操作转速下之风扇噪音、并分析其声音品质；另外在舌端上不同的轴向位置撷取其压力扰动频谱进行相干性分析，探讨舌端上因不同叶轮扭转角对周期性压力扰动之破坏之探讨。

The new design has a bifid tip and S-shaped spatula to exertmore effective pressure in the vallecula area, elevate the epiglottisand change directions of the forces on the tongue to preventposteroinferior displacement of the compressed tongue in thesubmandibular space during laryngoscopy.

新型设计有一双尖端和 S 形压舌片以便在沟回部位更有效施加压力，提升会厌和改变施于舌的力的方向，以防在下颌下部位喉镜压迫舌头导致舌头后下位脱臼。

Result:The genioglossus muscle originates from the superior mental spine,and the geniohyoid muscle originates from the inferior mental spine.

结果 ：颏舌肌和颏舌骨肌分别起于上、下颏棘。

Figure 6 The structure of normal working hours when the water pump, water pressure to automatically open the tongue plate, when a sudden stop, the tongue plate back in the self and the role of water close.

其结构见图6当水泵正常工作时，水压力使舌板自动开启，当突然停车时，舌板在自重与水倒流的作用下关闭。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.
