  1. Measures for further developing concrete mix design were presented based on above work. for example, adopts pfca as an index in designing durability of concrete, uses mortar slump flow test to select cements and water - reducers and to measure saturation dosage of water - reducer in mortar and then determine optimum dosage of it in concrete, uses bar - slump test to determine stability and fluidity of fresh concrete, and consequently, the workability of high fluidity and high stability concrete such as pumped or self - compacting concrete can be designed by adopting proper cfvm determined in terms of rheological properties of designed mortar measured with cone - based rheometer

    如採用粗集料破碎率作為耐久性設計的一個指標;採用砂漿坍落擴展度試驗選擇水泥和減水劑,確定砂漿中減水劑的飽和摻量,並通過上述數學模計算混凝土中減水劑的飽和摻量,以此為參照確定最佳摻量;採用障礙坍落度試驗確混凝土的穩定性和流動性,結合由漏斗式砂漿流變儀測定的砂漿流變性能確定合理的砂漿填充系數,從而實現對高流動性高穩定性要求的混凝土(如泵送和免振自密實等)的工作性設計。
  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。
