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。

Angular distribution for scatterings of 3He、4He、6He and 7He with hydrogen bromide molecules are calculated by using close-coupling approach from the anisotropic intermolecular potential of the He-HBr system established by the author. The calculations are performed separately at the collision energies of 60 and 100 meV. The influences of He isotope atoms on angular distribution is discussed in detail.
基于作者构造的He-HBr体系的各向异性势,采用密耦方法计算了碰撞能量分别为60和100 meV时3He、4He、6He和7He被HBr分子散射的角分布,详细讨论了氦同位素对散射角分布的影响。

We can draw a conclusion from the comparison between natural number and meaning that both exactness and fuzziness are meaningful only lying in a cognitive field and the former is relative, which can only exist at a static and close system; while the latter is universal, which is the result of being the cognitive reference point. Both exactness and fuzziness come from the interaction of the cognitive subject and object, and they are dialectical and unitive, based on the historicity and infinity of human cognition, which determines what we can do, is just to hold the continuum by discreteness and infiniteness by definiteness.
从自然数与意义对比得出的结论是:精确性只存在于一个静态的封闭系统中,是相对的,模糊性是语言充当人类认知参照点的结果,是绝对的,这两个概念都只有放在某个人类认知场才有意义;精确性和模糊性都来源于认知主体和客体的相互作用,它们是辩证统一的,其辩证统一的基础在于人类认识的历史性、无限性决定了人类只能够用离散来把握连续、用有限去追求无限。

That close-shaven turf, those pebbly paths, that chalk, those pools, those harsh monotonies of waste and fallow lands, the plants of early market-garden suddenly springing into sight in a bottom, that mixture of the savage and the citizen, those vast desert nooks where the garrison drums practise noisily, and produce a sort of lisping of battle, those hermits by day and cut-throats by night, that clumsy mill which turns in the wind, the hoisting-wheels of the quarries, the tea-gardens at the corners of the cemeteries; the mysterious charm of great, sombre walls squarely intersecting immense, vague stretches of land inundated with sunshine and full of butterflies,--all this attracted him.

The integral organism carries out complete self-movement and self-organization, while none of the parts can carry out such separate self-movement only by acting in close interconnection with other organisms and subject to the determination of high-level organism. For example, the autorotation and revolution of the Earth and other planets can be realized only under the deterministic role of the center of solar system. The movements of solar system and various stellar systems can carry out only under the greater deterministic role of the Galaxy, and the movements of the Galaxy and numerous galaxy clusters can only be realized under the context of deterministic role of the metagalaxy. By such analogy, the organic feature and constitution of the universe can be found out, no longer limited to the superficial dispersive interconnections between local individuals and those in small range of the metagalaxy.
比如,地球和众多行星的自转公转一定要受太阳系中心的决定作用才能成立,太阳系和众多恒星系的运动一定是在银河系中心这个更大的决定作用之中才能成立,银河系和众多星系集的运动一定是在总星系的决定背景中才能成立,以此类推就可以发现宇宙整体的有机性和构成关系,而不再局限于表面上分散的局部个体和小范围联系。
