氫核束-
The refractive index and the changing behaviour of the a - sic : h films were calculated by using uv - vis - nir spectroscopy interference wave and it was found that the hydrogen content and ir transmittance were decreased with y rays irradiation dose. lt is very interesting that the sp ' c - h bonds were observed by the raman spectra for the first time and expand the application scopes of raman spectroscopy in structure analyse fields
根據uv ? vis ? nir光譜中的干涉條紋，計算出了y射線輻照下a - sic ： h薄膜的折射率及其變化趨勢，並由此得出y射線輻照導致其氫含量變小及紅外透過率變小的結論。有趣的是：還首次用raman光譜觀察到了dlc薄膜中sp ~ 3c - h鍵隨輻照劑量改變的變化規律，擴大了其在結構分析領域中的應用。 -
So, y rays, compared with the other particles, have some particularity in acting with materials. the uv photons, exceeding our expectation, can break the sp ' c - h bonds easily
因此，文中y射線與薄膜作用時，與其它粒子相比確實出現了一些特殊性。紫外光子對sp ~ 3c - h鍵的破壞能力如此強，確實出乎我們的意料。 -
The y rays, neutrons, n ions and uv photons have different irradiation behaviour on the films by the study of this dissertatioathe y rays was much weaker than other particles if considering the breaking ability to the sp ' c - h bonds only
通過本文的研究發現， y射線、中子、 n ~ +及紫外光子對薄膜的作用效果明顯不同。從對sp ~ 3c - h鍵破壞能力方面考慮，中子、 n ~ +及紫外光子最強，而y射線最弱。 -
Dlc and a - sic : h films were prepared by the rf glow discharge and the reactive sputtering method respectively. there were two reasons that we chose y rays, ultraviolet ( uv ) photons, and neutrons as radiation sources. one is that y rays, uv photons and neutrons irradiation are serious at outer space and / or nucleus irradiation enviromentthe other is that the study on y rays irradiation on the films is a new and an important directioaotherwisejirnited reports have been made of the investigation on the uv photonsjieutrons irradiation influences on these films
本文分別採用射頻（ 13 . 56mhz ）等離子體cvd及射頻反應濺射方法制得了dlc及a - sic ： h薄膜。文中主要選擇y射線、紫外光及中子作為輻照源有兩方面的原因：一方面，在外層空間， y射線及紫外光輻射十分嚴重，而在核輻射環境下y射線及中子輻射也不可忽視；另一方面， y射線輻照這兩種薄膜完全是一項開創性的工作，同時國內外對紫外光子、中子與這兩種薄膜作用的研究也很少。 -
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。
