  1. The complicated life cycle of streptomyccs is one of the most important reason that attracts researchers on its genetics. a great deal of valuable information on the morphological, physiological differentiation of streptomyccs coclicolor will emerge after genome sequencing is completed. based on the s. coelicolor dna sequences that have been finished and focusing on three ftsk homologous, which may be closely related with cell division, this study tried to find out the functions of three ftsk homologues genes by gene replacement or disruption

    黴菌雜的生活史是研究其遺傳學的一個重要原因,天藍色黴菌全基因組測將會為其態及生理分化發育的研究提供大量用的信息,本研究基於天藍色黴菌已測出的98列,對一組可能與細胞分裂關的基因? ftdk同源基因? ?進行基因置換或中斷並對其功能進行初步研究。
  2. In this paper, i will present some algorithms of polyhedral visual hull reconstruction : ( 1 ) polyhedral v isual h ull generation a igorithm b ased one dge - pool - searching, which constrains the 3 - d intersections into the 2 - d planes intersection via the epipolar theory to reduce the complexity a nd c an r educe t he t imes f or c ones t o b e p rejected o nto t he i mage p lanes, i n which we induced the index list to every points on the surface of object, and connected the related points to get sub polygons on surface and in turn get the mesh model, we replace triangulation process of disordered points cloud by edge - pool searching. ; ( 2 ) reconstruction based on degenerated - polygon - intersection, which have the following improvements on traditional bull intersection : using degenerated polygon to orga nize intersected area on cone face, which may be discontinuous ; a fast intersection algorithm of polygons on the cone face based on degenerated polygons, which is consistent between the continuous polygons and the discontinuous ones. the intersection of degenerated polygons is similar to the convergence of two ordered lists, which is comparably simple to the bull operation ; ( 3 ) reconstruction algorithm based on ray - tracing, in which all the rays that run through the vertex on silhouette of object will intersect with all the cones correspondent to other silhouette, and we have to calculate the intersection of all such line segments, the endpoints of which are considered to lie on the surface of object and we will get the point cloud on the surface of object

    同時利用共極線原理把三維計算投影到二維平面以降低求交計算的雜度,該演算法可以減少光錐向圖像平面投影計算的次數,以邊池搜索取代散亂點集上進行的三角剖分; ( 2 )基於退化多邊求交的多面體可見殼模型重構,系統引入退化多邊的概念,把錐體平面的交集中不連通的部分用一個退化多邊來表示,並引入了新的基於退化多邊的求交演算法,與傳統多面體可見殼重構相比,該演算法以下幾點創新:在圖像平面以退化多邊組織投影錐體和物體輪廓的交集,把任意錐面與物體輪廓的交集歸一到一個退化多邊;基於退化多邊的二維平面上多邊快速相交演算法,該演算法在一定程度上就是兩個表的合併,大大簡化了先前的布爾求交計算; ( 3 )基於光線跟蹤的演算法,該演算法中所通過輪廓頂點的光線和對應其它圖像輪廓的光錐進行求交計算,最後得到每次求交計算得到線段的交集,該線段的頂點就認為是物體表面點,從而得到物體表面的點雲。
  3. When ba / sa = 3 / 1 - 9 / 1, longer domains ( ba ) are in majority, and some hydrophobic " holes " ( caused by the difference in height between ba and sa ) formed in the alkyl layer which can be used to fabricate special functional nanostructures

    衍射強度出現「 w 」狀變化,表明在中間比例所成的長短交錯的結構向兩邊變化時,都要經歷混合膜度降低的過程。這為制備合膜時比例的選取,提供了意義的數據。
