  1. By taking advantage of parallel lines and orthogonal lines in architecture, the camera internal parameters, rotation and translation can be recovered from a set of un - calibrated images via computing absolute conic and vanishing points. the euclidean 3d model of architecture ( up to a scale factor ) can be recovered too

  2. But all designed software before in our country still have some weakness, for example, the conventional type of cam counld be projected by these software is very little, and used approximation by lines to curves of cam which have bigger error and more nodal points that result in chattering of principal axis. in furthermore, this software of designing cam in fact only has the function of cad. if you want to simulate and work over the designed cam in that software, you will find that you have to export it to other cad / cam system software ( e

    隨著數控加工在我國的深入開展,真實現我國的凸輪cad cam就顯得非必要,但以往的凸輪設計軟體還存在許多不足,如可設計的凸輪類型較少,大多集中於平面凸輪;且採用誤較大、節點數過密的直逼近法生成凸輪工作,造成計算間長,且加工中產生較大振動;同這些凸輪設計軟體基本上只具有cad功能,如果想將設計好的凸輪進行模擬和加工,就必須將圖形輸出到其它通用cad cam軟體(如mastercam等)中,因此這些軟體在實際應用中總不盡人意。
  3. Several influence factors to result plasma drift in hainan were analyzed. in this paper the characteristics of ionospheric parameters variation were analyzed systematically and some new results in storm - time such as seasonal behaviors were obtained ; it is the first time to investigate the ionospheric drift behavior in hainan and some new results was obtained, the relationships between each two plasma drift velocity components in storm time in hainan were found and the electric filed variation in hainan ionosphere also was obtained ; the results also show that there are big differences of the ionosphere parameters bo and bl obtained from the data with that obtained from the iri - 2001 applied for hainan ; a new phenomena was found during a strong magnetic storm, that a layer with very strong electron density and density grad was found during the recovery phase of the storm, its horizontal scale is beyond 100km and temporal scale is about 2 hours, this phenomena repeated 3 times continuously. a type of negative disturbance in high and low latitude but positive disturbance in east - asia also has been found

    本文較為系統地給出了海南地區電離層的參數變化特徵,特別是得到了一些暴與以往不同的季節特性;第一次給出了海南地區的電離層等離子體漂移特徵,發現等離子體漂移暴擾動在三個方向上有內在的聯系,得到了電場變化;研究結果還表明海南電離層的半厚指數和形狀參數等與國際參考電離層iri - 2001存在很大別;通過對強磁擾動事件期間的參數變化特性分析發現,在磁暴恢復相期間海南地區電離層底部存在一個電子密度非大的高密度區,高密度區底部電子密度梯度隨高度急劇增加,該區域的水平尺度可達100公里以上間尺度約為2小,連續出現過三次,這是一個在海南從來未發現的新現象;研究還發現了暴東亞地區電離層擾動會出現高低緯負相而中緯相的現象。
  4. Based on the simple understanding of normal seismic processing, this paper has carried out deep research on the problems of deep prospecting in seismic data processing, such as s / n ( signal to noise ratio ), velocity analysis and residual nmo of unsymmetrical hyperbola, stacking and imaging of complex rays and migration arc. until now tens of accomplishments have been achieved

    在簡單了解地震資料規處理的基礎上,本文針對當前深層資料的問題,緊緊圍繞著深層地震數據處理技術研究需要解決的重點問題,即信噪比問題、非對稱雙的速度分析與剩餘動校問題、復雜射的迭加及偏移成像問題和偏移畫弧問題等,進行了深入的研究工作,目前已完成十多個成果。
  5. This paper focuses on the research of fuzzy control, especially rule self - adjusting fuzzy control method. by theoretic analysis and simulations, the influences of parameters and system performance characteristic of some kinds of rule on - line self - regulating fuzzy control methods are discussed, and a novel real - time self - adjusting fuzzy control method ( vsrsafc ) is proposed from the diagrammatic point of view. in vsrsafc, the slope of the rectifying curve of rule scaling factor a is altered by the fine - tuning and coarse tuning combined mechanism to adjust the fuzzy control rules according to error e and error change ec, which more coincides with characteristic of system response than the conventional self - adjusting method that adjusts rule scaling factor only according to the error e, and has better static and dynamic performances than the latter

    其中變斜率規則自調整模糊控制的效果較為明顯,它是基於插值的非性規則自調整模糊控制的引申以及規全論域規則自調整模糊控制的改進,該方法採用粗、細調結合機制,通過改變規則調整因子的修斜率,使系統同根據誤e以及誤變化ec在調整模糊控制規則,比傳統的僅基於系統誤e的自調整方法更符合系統響應特性,可獲得更好的動靜態控制性能,特別是對于系統參數發生改變、控制參數選取不當等不良狀況,控制器仍能較快自調整,具有較強的在自適應能力。
