In fact, laser beam quality is a main parameter that has key action on laser materials processing from the beginning to the end. in this dissertation, the parameter used to evaluate laser beam quality is proposed. the influence of beam quality on beam propagation and focus are studied in theory and measurements separately
本文以光束質量為主線，研究了光束質量對激光製造技術貫穿始終的重要作用，提出了以描述激光束聚焦特性為核心的光束質量評價參數;理論分析，並實驗驗證了光束質量對光束傳輸和聚焦性能的影響;最後，以激光焊接為實例，研究了光束質量對激光加工過程的影響。Moreover, little limitation from intellectual property right, compete - prohibited clause and occupational moral cost the participators little to expropriate. not only can the new enterprises cheaply use knowledge and other critical sources the old enterprises accumulated, but also can be more efficient in accumulating new complementary impersonal knowledge because of its clearer property right structure. all those provide irresistible lure for the participators who have higher ability in accumulating knowledge
再加上整個社會的制度環境對于產權保護的不力，沒有競業條款和職業道德對企業參與者的約束，使得參與者背叛的成本很低，而新成立的企業在產權上更為清晰，它不光可以廉價地從老企業轉移知識積累和其他核心資源，更可以高效率地繼續積累互補性客觀知識，這無疑是對那些具有較高知識積累能力的企業參與者非常重大的誘惑。Based on analyse of parameters which used to evaluate laser beam quality at present and according to the main properties which influence on laser manufacturing, beam focus characteristics parameter is put forward as the stander parameter to evaluate beam quality, because the foundmental advantage of laser beam applied in industral field is that laser beam can achieve high energy intensity through focusing
論文在總結目前存在的評價激光光束質量參數的基礎上，根據對影響激光製造的主要光束特性參數的分析，以光束空間特性為核心，提出用光束聚焦特徵參數值作為評價激光光束質量的參數。因為激光作為能源能夠在工業領域廣泛應用的根本優勢就在於它可以通過聚焦獲得極高的能量密度，而值恰恰表徵了實際光束的可聚焦能力。A solution for traffic engineering design based on gmpls is demonstrated in this study. the solution is based on the analysis of the technical theory, implementation mechanism and core technology of gmpls and featured in its constraint - based routing. by using the expansion and combination of the existing protocols, the solution composes of 4 parts : packet forwarding module, information distribution module, path selection module and signaling module
本文的研究工作是作者在大唐電信「基於wdm技術的多業務智能光網路系統」可行性研究小組在gmpls研究方面的一部分，在對gmpls的基本技術原理、實現機制以及核心技術進行研究分析的基礎上，針對gmpls的約束顯式路由技術特點，作者在本文設計了一種基於gmpls的流量工程解決方案，它充分利用了現有協議的簡單擴展和組合，該解決方案包括四個基本組成部分：包轉發單元、信息發布單元、路徑選擇單元和信令單元。As microwave communication ca n ' t meet for quickly increasing recently demand for bandwidth, it is necessary for developing optical intersatellite communications techniques. but the acquisition, tracking and pointing ( atp ) are critical and difficult issues in optical intersatellite communications
空間光束捕獲跟蹤對準atp （ acquisition ， trackingandpointing ）技術成為空間光通信鏈路和網路的核心支撐性技術，目前已成為研究、關注的重點。Based on research of the fringe method, the midline method, the depth restrict method, and so on, the paper puts forwards new method of contour extracting - - the gray barycenter based on edge ( gbbe ). contour extracting is kernel problem of slim
論文在分析了邊緣法、中線法、基於骨架的灰度重心法、深度約束法等輪廓提取方法的基礎上，對結構光圖像法的核心問題一一光帶輪廓提取，提出了一種新的光帶提取方法? ?基於邊緣的灰度重心法。分享友人
