中文拼音 [kēdòngcháng]
科洞常
英文
kohn anomaly-
Black holes are some of the most mysterious objects of the universe. a mere mention of the name invokes a sense of enormous cosmic power at work
黑洞是宇宙中最神秘的物體之一，只要提及黑洞這個名稱，便會使人聯想到宇宙中強大的力量，難怪它成為科幻電影常常描寫的對象。As to the current problems existing in the identification for these flutter derivatives, the dissertation tries to trace the development in the identification for the past unsteady aerodynamic forces of long - span bridges. it also investigates the method for flutter and buffeting analysis and the flutter derivatives. based on the present methods used in obtaining the unsteady aerodynamic forces and flutter derivatives, and co - funded by a natural scientific fund from the nation and a key project fund from the railway ministry, the current research has attempted to develop a device which can be employed in the wind tunnel to test flutter derivative through a forced vibration method
鑒于目前橋梁斷面顫振導數識別的水平和存在的問題，本文通過對大跨度橋梁非定常氣動力、顫振分析方法及顫振導數識別方法的回顧和評述，基於現有的非定常氣動力和顫振導數的測試方法，在國家自然科學基金與鐵道部重點學科基金的聯合資助下，研究開發了一套在風洞中採用強迫振動法測試顫振導數的裝置。By taking advantages of epipolar line features and depth discontinuities in reference 中國科學院 軟件 研究所 博士 學位 論文 基于 圖 象 的 快速 繪制 技術 的 研究 images ， an efficient inverse wmping algorithm is pfoposed in chapter 3 for gcnerating nagcs of novel views by combining multiple eference images 帆 enhm different vie 呷 oints because continuous segnents determi 。 d by pairs ofedge pixels at co 。 spending epipolar lines are order kept ， only pairs of edge pixels in the reference 渝 明 e e necess 叨 口 cowute to obtain generalized disparity of all points in the desired image as a result ， sighficant acceleraion could be made in the endering pfo 比 鴕 two accelerating techiq 此 s e presented in this algori 山 mb accelerate the hole illing process his algorithm extends the reference images rom projection of single col ： ii ’ ected surface in previously developed nvnverse w 出 下 er to ima 驢 s captured rom complex scene in chapter 4 ， an 《 dent ibr method is prese 庇 仙 y takn ull 訕 antage of 呷 bies c 咖 the method can simulate the 3d details on sllri ： ace of object successfully he 。 叩 proach ， called rered ature mopmp consists of two pans at fst ， an origi 。 ltexture with orthogonal displacements per pixel is deco 啊 osed into a series of new t6 刀 mfcs with each 他 lug a given displacement per pixel ， called ae ， ea atures ， or lt hen hese lt e used to render the novel view by conventional texture mapping d avoid gaps n the endered hlla 驢 ， some phels are to be interpolated nd extended in the 廠 kaccoding to the depth differe eee between two neighbor pixels in the original texture as these ltlt fc … e much storage nd therefore much time is equired to install ltlt into the text ’ ufc buffec an 舊 thod is pfoposed to co 呷 fcss the ltlt ， nd the cottcspondingfclldering method is given experimental esults show that the new method is efficient ， especially n rendering those objects with a smaller depth rnge compared withtheir size ， such as relief surfaces of building
與己有的三維變換方法相比較，該方法不但成功地填補了由於投影區域擴張而產生的第一類空洞，而且成功地填補了由於空間深度非連續物體相互遮擋而產生的第二類空洞，從而方便地實現了虛擬環境中的漫遊；基於物體表面深度的連續性，本文提出了一個位移預測方法? ?此方法可以從單幅參考圖象獲得逆映射過程中所需要的目標圖象的位移信息，從而大大提高了演算法的效率：與通常的正向映射演算法相比，此演算法克服了多幅參考圖象所帶來的計算量成倍增長等問題，而且誤差較小。 2 ）基於極線幾何的快速逆映射演算法。利用參考圖象的邊界信息與隱含的遮擋關系，以及極線幾何的性質，本文第三章提出了一個基於極線幾何的快速3 『一中國科學院軟體研究所博士學位論文基於圖象的快速繪制技術的研究逆映射演算法，從多幅參考圖象精確合成當前視點目標圖象。In the first part, the actual studies in the pre - primary education do n ' t pay enough attention to attaining forceful supports by adopting the newest discoveries in the neuroscience. therefore, it is inevitable that many paradoxes emerge in the theories of pre - primary education and many mistakes have been made in the practice
第一部分：由於沒有及時吸納現代腦科學研究的最新成果，缺乏該領域新理論的有力支持，現行的學前教育不可避免地常常出現理論上陷入難以自圓其說的困難境地，實踐中出現種種弊端、漏洞。The construction processes of large - scale underground structure group are very complicated. in order to quicken the construction processes, reduce price and assure success, it is necessary that adopting scientific system simulation method to simulate the whole construction processes, to make all tunnels, all activities and all machine equipment harmonious and make construction sequence schedule reasonable
大型地下洞室群施工過程是極其復雜的，採用科學的系統模擬方法對地下洞室群施工全過程進行模擬，使各洞室、工序及施工機械設備相互協調配合，使洞室群施工順序和施工進度計劃更加合理，對于加快洞室群施工進度，降低工程造價，保證工程順利進行非常必要。In science fiction, we often read that a worm hole will connect two places in the universe
：在科幻小說里，我們經常可以看到作者利用蟲洞作為連接宇宙兩處地方的捷徑。分享友人
