Aiming at the great challenge of deepwater oil resource exploitation in 21st century china, this paper firstly explained contents of offshore engineering joining technology, then introduced a series of important technologies such as deepwater pipeline laying welding, local dry welding, underwater hyperbaric welding, and friction stir welding, lastly put forward countermeasures to develop offshore engineering joining technology in china
摘要在解釋海洋工程連接技術內涵的基礎之上，針對21世紀我國海洋石油開發深水資源的巨大挑戰，對深水海底管道鋪設焊接、局部乾式焊接、水下乾式高壓焊接以後摩擦疊焊等重要技術進行了介紹，最後提出了發展我國海洋工程連接技術的對策。 -
As the values of wave factors in period of reoccurrence were deduced for many significant propagating direction in the yangtse river estuary, the wave reflection - refraction modeling is employed in terms of the equations with the slowly varying topography, and the influence on the effects of the channel and shoaling is included in this model. at the same times, the effects of the bottom friction and wave breaking are also considered, but the local wind field and background flow are ignored
在推算長江口深水航道幾個主要波向的重現期波浪要素值時，採用了基於緩坡方程的波浪折射?繞射模式，該模式考慮了航槽和淺灘對波浪的影響，同時也考慮了底摩擦和波浪破碎對波浪的作用，但未能考慮局地風場和流場的作用。 -
Result of study indicates that the momentum input along with the branch flow toward the downstream and the additional friction induced by the mixing of main streams with branch flows should be considered for rational analysis of the local energy loss at junctions
研究結果表明，正確分析管道匯流口水流的局部能量損失機理，必須考慮匯入斷面上支流沿下游主流方向的動量輸入和主支流間相互摻混引起的附加摩擦阻力的影響。 -
We may all agree that the local physics of fracture or friction play a strong role, but how do these scale from the controlled conditions of the laboratory to the field case, how do we account for changes in the boundary conditions, and how do we take into account the strong interactions between faults during earthquakes
我們可能都同意破裂或摩擦的局部物理性發揮重要的作用，但是如何將基於實驗室控制狀況獲得的這種信息用來標度現場地震事例的情況，我們如何去計算考慮邊際狀況中的變化，我們又如何計算考慮地震期間斷層之間強烈的交互作用？ 」 -
The results predict the local friction reduction increases with the air injection ration hut decreases with the distance - away from the injection, which is in conformity with experiments
結果預示，隨著噴氣率增大，局部減阻率增加，但離噴氣口的距離越遠，局部減阻率減小。
