The application of transverse resonance theory is firstly extended further from plane homogeneous medium to the inhomogeneous spatial region by primarily combining the current martcatili method. then the simplex method is used to calculate the source point " s best position, frequency and the correspond wavenumber of the region
重點結合已有的marcatili法，首次將橫向諧振法從平面均勻分層介質中的應用進一步延伸到模擬地殼波導的三維非均勻空間區域中，再利用單純形法，確定源點在該區域的最佳位置、最佳頻率和對應的傳播常數。After collecting the material standard and documents, many defects to express steel bar ' s ductility using breaking elongation of steel bar are existed. with elongation ' s study of steel bars, in this paper the reasonable expression and measurement of elongation are discussed, that symmetrical elongation is scientific as actual ductility of steel bar is given, and the measurement with experiments is suggested
本文通過收集鋼筋材料標準和有關文獻，並對各種類鋼筋進行伸長率試驗研究，發現用鋼筋斷后伸長率（ _ 5 、 _ （ 10 ） 、 _ （ 100 ） ）表示鋼筋延性存在許多缺陷，提出用均勻伸長率_ （ gt ）作為鋼筋的延性指標，並通過試驗建議其量測方法。Secondly, the effect of transverse deforming on the property of the wedge pressing was studied. the results showed that : the wedge pressing stock with the transverse deforming amount of 10 % acquired the best performance. the highest density got the biggest rate of slope while with the amount of 30 % the curve was more some special structure and performance as following : the large porosities was crushed into small or linear ones with the high - direction deformation amount of 20 % ; as the increasing of the high - direction deforming, the particles got a further deforming, the porosities got a further crushing, the small porosities were mergered by the large ones and the former then disappeared ; when the amound reached 60 %, the quantity of the porosities would obviously decrease which made the materials compact, the microstructure more uniform and the density and hardness curves more horizontal, the relative desity could reach 99. 7 %, the tensile strength b of the as - compacted samples reached 408mpa with the yield strength s teached 289mpa and the elongation percentage reached 13. 6 %. in addition, the microstructure of the wedge pressing stock under the pressing temperectureof 450 was uniform, the porosities and the boundries of the grains basically disappeared and the conjunction between particles was great
採用雙向楔形壓制，大尺寸噴射沉積5a06鋁合金楔壓坯的組織和性能變化具有如下特點:當高向變形量為20 %時，大的孔洞變形破碎為小的孔洞，或呈線狀孔;隨著高向變形量的增加，顆粒進一步變形，孔洞進一步破碎，大孔「吞併」小孔，小孔塌陷並逐步消失;當高向變形量達到60 %時，孔洞量大為減少，材料基本緻密，組織趨于均勻，楔壓坯料的密度、硬度變化曲線接近水平線，坯料的相對密度達99 . 7 % ，抗拉強度_ b = 408mpa ，屈服強度_ （ 0 . 2 ） = 289mpa ，延伸率= 13 . 6 % ;對比其它的壓制溫度，在450楔形壓制的坯料組織均勻，孔洞及顆粒邊界基本消失，顆粒之間冶金結合良好。The results are follows : chemical composition, tensile strength, yield strength and elongation accord with standard, part corrosion of outside is dew point corrosion, equable corrosion of inside is brought by deoxidized water
結果表明：其化學成份、抗拉強度、屈服強度、延伸率均符合標準要求，管材外表面局部腐蝕是因露點腐蝕造成，管材內表面受除氧水的作用均勻腐蝕。There are several problems in scalable and reliable multicast, such as, feedback implosion and local recovery, etc. aim at to solve the problem of feedback implosion, we discuss carefully how to set the timer to avoid the nack implosion in receiver - initiated, integrate fec system. we propose two methods : divided time equally and based on exponential distribution to set timers, divided time unequally and based on exponential distribution to set timers. by analyzing for up to 10 receivers, both of them can avoid the nack implosion and feedback delay due to timers is low
在可伸縮可靠多描通信中存在反饋信息爆炸、局部恢復數據困難等問題，為了解決反饋信息爆炸的問題，本文針對基於接收者啟動、使用集成fec的系統，詳細討論了如何使用定時器避免nack爆炸，提出了設置定時器時間的兩種方法：基於指數分佈、均勻分段方法和基於指數分佈、非均勻分段方法，並且分析了它們抑制nack的能力和由定時器引起的nack延時長短，通過分析可知：對接收者數量達到10 ~ （ 10 ）數量級的多播通信，這兩種方法都能避免反饋信息爆炸，且由定時器引起的nack延時短，並且后一種方法優於前一種方法。Based on theory analysis and lots of experiment data, converting relation of symmetrical elongation and breaking elongation of testing steel bars have been tropical and the reference to consolidating ductility is provided. at last, in this paper consolidating steel bar ' s ductility by comparing to stress - strain curves of steel bars and is assessed
在理論分析基礎上結合大量試驗數據，回歸出各類試驗鋼筋均勻伸長率_ （ gt ）與斷后伸長率_ 5 （ _ （ 10 ） 、 _ （ 100 ） ）的折算關系，為統一延性評定指標提供參考，進一步比較鋼筋應力?應變曲線和_ （ gt ）值，最終統一評定我國混凝土結構用鋼筋（絲）的延性性能。分享友人
