  1. The urea - formaldehyde ( uf ) polymer / sio2 composite microspheres were prepared by polymerization - induced colloid aggregation ( pica ) method. the formation mechanism of composite microspheres is attributed to the fact that that urea and formaldehyde firstly undergo acid - catalyzed polymerization to form oligomers, and then the sol particles are adsorbed on the chain of oligomers by wan der walls force and hydrogen bonding. when the oligomers reach the critical chain length, they separate from solution due to phase separation

    對復合微球形成機理的研究表明，尿素和甲醛在酸性條件下自身聚合可以形成高分子微球，在sio _ 2酸性溶膠中發生聚和反應時，隨著反應的進行，齊聚物不斷生成， sio _ 2膠體顆粒逐漸吸附在齊聚物分子鏈上，當聚合物鏈達到沉澱臨界鏈長時，由於相分離作用，從前驅物溶液中析出，同時sio _ 2膠體顆粒均勻的分佈在脲醛聚合物網路中，隨之沉澱出來，形成脲醛sio _ 2復合微球。
  2. This paper introduces fint the mechanism and trend of industry chains integration in relation to the theory on value chains and modularity, and analyzes several forms of industry chains integration based on three factors : ( 1 ) the complexity of transactions, ( 2 ) the ability to codify transactions, and ( 3 ) the capabilities in the supply - base and then highlights the integrated mechanism of value chains and value modularity

    本文從價值鏈與模塊化的相關理論出發，闡述了產業鏈整合的機制與動向，並在交易的復雜性、信息可編碼識別的程度和供應商能力三要素的基礎上，分析了產業鏈整合的諸形態，重點對價值鏈與價值模塊的整合機製作了較深入的探討。
  3. 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復雜度，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 ）基於退化多邊形求交的多面體可見殼模型重構，系統引入退化多邊形的概念，把錐體平面的交集中不連通的部分用一個退化多邊形來表示，並引入了新的基於退化多邊形的求交演算法，與傳統多面體可見殼重構相比，該演算法有以下幾點創新：在圖像平面以退化多邊形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形；基於退化多邊形的二維平面上多邊形快速相交演算法，該演算法在一定程度上就是兩個有序鏈表的合併，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，該演算法中所有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。
  4. First the thesis analyses the foundation of strategic alliance by using some theories of value chain, transaction costs, organizational study, etc. based on the previous research, view of strategic alliance and different classifications is brought forth. actually the establishment of strategic alliance is complex systematic work, an alliance ' s stability depends on selecting proper companions, building relevant framework, keeping mutual trust and creating cooperative environment

    本文首先從價值鏈、交易費用、組織學習等不同角度分析了戰略聯盟形成的理論基礎。在總結前人的基礎上，提出自己對戰略聯盟的看法，並介紹了戰略聯盟的不同分類。組建戰略聯盟是一項復雜的系統工程，聯盟的穩定發展有賴于選擇合適的聯盟夥伴，建立相應的組織結構，保持穩定的信任關系以及創造合作的文化氛圍等。
