In section one, by using fice scheme and time - gcm, a model of trace gases and oh airglow affected by gravity wave is set up, then the propagation of nonlinear gravity wave and the effect on trace gases and oh airglow are analyzed. the result shows gravity wave excited by tropospause forcing can propagate stably to the mesosphere through the stratosphere so that energy and momentum can be transferred from one region to another. in this process, gravity wave undergoes growth, overturning, convection and breaking

縱觀有限元分析技術的發展,目前大多集中在建立良好的用戶界面上的研究仍存在許多應用上的局限性,其中對任意剖面上可視化的研究仍處于方興未艾的階段。要實現任意剖面上可視化處理,必須先將得到的有限元計算結果進行再處理,因此在演算法上分為兩部分:求任意剖面上物理量值的演算法及二維等值線演算法。前一部分以彈性力學中「任意斜截面的應力」為理論基礎,利用線性插值方法得到截面與單元棱邊的交點坐標及交點物理量值;在此基礎上;根據已得到的單元及節點序號表、應力應變物理量表,總結出一種基於有限元剖分網格的快速生成二維等值線的演算法。The discovery of otoacoustic emissions ( oae ) is one of the most important progress in hearing physiology and audiology

摘要綜述了氣象學的三大領域大氣動力學、數值天氣預報和氣候學在20世紀的研究進展。Establishing an human spine dynamic model is an significan event to study spine injured biomechanics of pilot " s ejective injury, parachute opening, landing and study the endurance to impact loading on human spine. in this paper, the huston " s method of kane " s equations is developed so that it can be applied to the multibodysystem including translation between the bodyies. the dynamic model of human spine is provided basing on these theories, while the big movement of spine is considered. the deformation of vetebra is far smaller comparing with the intervetebra disc, so the spine is considered into multibodysystem including rigid bodies ( vetebra ) and the flexible bodies ( intervetebra disc ). the computer solution correspond with the results of the large scale human impact test. the rigid coefficient factors and the damping factor of intervetebra joints are obtained
人體脊柱動力學模型的建立對研究飛行員彈射救生、傘兵跳傘開傘、著陸等脊柱損傷的生物力學以及研究人體脊柱耐受沖擊載荷的極限問題都具有重要意義.首先發展了凱恩方程的休斯頓方法,使其可應用於變形體連接的多體系統,並以此理論為依據建立人體整椎脊柱沖擊動力學模型,此時考慮脊柱的大位移運動,每個椎骨的變形相對椎間盤的變形小得多,把脊柱看成由剛體(椎骨)和變形體(椎間盤)組成的多體系統.並以大型真人坐姿沖擊實驗結果進行了擬合,最後得到腰椎間關節剛度系數因子和阻尼系數因子Review on biological mechanic research development of ankle plantar flexion and dorsiflexion
