  1. 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
  2. Choose two nodes on the edge of the structural to compare the results calculating by the finite element program midas, then we can draw a conclusion that these kinds of space truss systems is sensitive to the libration of the dynamic wind loads. to consider this factor is very necessary in the process of design, we will use the pulsant augmentation coefficient to realize it

    比較靜力風荷載和動力風荷載作用下的有限元軟體的計算結果，選取結構邊緣部分的兩個節點，對比它們在兩種方法計算下的最大位移的計算結果。經過比較可以看出重量輕、頻率低、阻尼小的柔性建築物對風荷載的橫向振動是很敏感的，在進行工程設計時應該考慮這種因素，並可採用乘以風振系數等相應方法來加以體現。
  3. The more streamlined an object is, the less drag it encounters.

    一個物體越呈流線型，它遇到的阻力就越小。
  4. Abstract : in light of thicker grain and smaller viscosity of debris flow, a segmented simulation of the debris flow with flume is presented. for the first time. more difficult resistance similarity is brought about by geometric rate without excessive coarsing and discontinuous similarity of sand grain composition in model is eliminated with different grain scale. on this basis the density similarity and sand conveying similarity are achived. the method presented is verified through a model test case

    文摘:針對水石流顆粒粗，粘性小的特點，提出了利用水槽進行分段模擬水石流的設想，首次通過幾何變率解決難度較大的阻力相似問題，改變了以往過度加糙的方式;通過變粒徑比尺的方法消除了模型沙級配不連續相似的問題，較好地實現了固體物質級配相似，達到了泥石流的密度相似和輸沙相似.通過水槽概化模型試驗實例，對本方法進行了驗證
  5. According to the marketing survey report made by the joint effort of mercer managing & consulting company and china logistics & purchase association, china ' s third party logistics ( hereinafter referred to as tpl ) market is in its primary stage with great potential and rapid development. by virtue of their failure to provide diversified services especially in value - added services to the customers, most of chinese logistics suppliers get few satisfactions from their clients. furthermore, the further development of tpl is blocked by the small scale of chinese tpl enterprises, serious backwardness of logistics equipments and information technology, outdated conceptions and systems and scarcity of qualified logistics persons

    根據美智（ mercer ）管理顧問公司與中國物流與采購聯合會合作的中國第三方物流市場調查報告，我國第三方物流市場正處于發展的初期，雖然潛力大、增長迅速，但物流供應商功能單一，增值服務薄弱，客戶滿意程度不高，而且我國第三方物流企業規模偏小，物流設備和信息技術落後，舊觀念、舊體制和物流人才的缺乏都阻礙了第三方物流的發展。
