當焊劑變成液態並且在管道和閥門上呈現半透明狀態時，開始將火焰沿著連接部件的軸線進行進退烘烤，以保持連接部件、特別是閥門套筒底座部位的熱度。In this paper, three unique models were designed to research atom diffusion at interface, contacting line and joining point under bpec heating and compare with it under radiation heating in order to find out if bpec speed atom diffusion. the first model was aimed to research atom diffusion at interface under bpec heating. experiment condition of bpec diffusion welding sheet cu and ni : direct diffusion welding, at a pressure of l0mpa, welded at 750 ~ 900, with heat rate of 200 ~ 400 / min for 10mm, on / off of 6 / l ~ 48 / 8, with die or not, vacuum of 6pa
本文設計出三種樣品預構件，研究脈沖大電流加熱條件下片狀材料、線狀材料和球形顆粒之間的原子擴散過程，弄清脈沖大電流加熱條件下原子擴散與一般燒結和焊接過程中原子擴散的區別，以證實特殊的電場和磁場是否對原子的擴散有推動作用，揭示脈沖大電流加熱條件下原子的擴散過程，探索脈沖大電流熱加工技術快速高效的原因。Then an thorough computer modeling using finite element program with material, geometry and state triple - nonlinear taken into account is carried out on a series of influencing factors, such as comparison with npn - beam splice connection, comparison of varies designed theories, and the varying of fraction coefficient, diameter, grade, pretension and arrangement of bolts, thickness of web and flanges of beam and column, splicing location, axial loading on column, etc. lots of useful conclusions are drawn form computer modelling. finally, design and construction suggestions are given out. this study fills the black in the field of steel beam - to - column connection with cantilever beam high - strength bolted - splicing at both home and abroad
然後，本文在考慮材料、幾何和狀態三重非線性的基礎上，對該連接形式進行了全面的計算機模擬，主要考慮了帶懸臂梁段全螺栓拼接的樑柱連接節點與無拼接的樑柱連接及翼緣對接焊接腹板拼接的連接節點的對比，各種設計方法之間的對比，以及翼緣拼接和腹板拼接的螺栓間距、直徑和數量，拼接點與梁端之間的距離，梁和柱的翼緣、腹板厚度，柱的軸力，接觸面的摩擦系數，翼緣和腹板拼接板的厚度等因素的影響。Components required to be mounted off the board are provided with lead forms at the board surface or other mechanical support to prevent lifting of solder land
需要離開線路板安裝的組件在線路板表面利用引腳形狀或其它機械支撐來防止焊盤的翹起。The distortion resulting from antenna ' s deadweight results that the fact surface departures the theoretical surface regularly. at the same time, because of moulding and weld fault, the measurement data departures the theoretical surface randomly. the process of the data processing is composed of three steps
雷達天線處于架設狀態下，由於自重變形導致實際面形偏離理論面，造成變形系統誤差；而蒙皮表面加工及焊點接觸不良則造成天線面的隨機誤差。These rules consist of the total fit, the mathematics and fatigue physics, and the safety in tail predictions. an analysis of the test s - n data of 16mn steel weld joints reveals that the four models are reasonable if only considering the total fit as the conventional method did. but if by the present three rules, the appropriate models should be the normal or the extreme maximum value
根據先前提出的有限數據下良好假設分佈的確定方法，包括三個原則，即假設分佈形狀與誤差數據真實分佈形狀的一致性、預測的總體擬合效果、與疲勞失效機制的一致性和尾部預測的安全性，通過對線性均值s - n曲線擬合16mn鋼焊接頭s - n數據誤差的統計分析，說明應用一般推斷方法， 4種分佈都可合理地作為數據的統計模型，綜合考慮三原則后，極大值和正態分佈是可能的良好假設分佈。It is found that, the modes of coaxial optical emission of dissimilar gaps, clustering at distinct numerical range, can distinguish 1st, 2nd and 3rd class welds of different welding quality effectively
結果表明，同軸光信號幅值的眾數在不同間隙的焊縫段，聚集在線性可分的不同的區間，可以有效分開焊接質量不同的類、類、類焊縫；信號的分段功率譜分析能夠較為直觀地反映焊接狀態的變化。分享友人
