butt coupling

基本解釋

Based on mode field coupling theory, a model to calculate the butt-joint coupling efficiency between a multi-mode fiber and a single-mode fiber is presented.
采用模場耦合理論，推導出多模光纖與單模光纖的直接耦合效率表達式，計算得到耦合效率與所選用的多模光纖和單模光纖的纖芯芯徑之間的模擬關系。
The relation between coupling efficiency and mode field stimulated by SLD, fiber structures, shape of fiber butt and coupling operation parameters was analyzed.
分析了耦合效率與光源激發(fā)的光模場、光纖結構及光纖頭部形狀、耦合工作參數等因素的關系。
Simulation of DC flash butt welding by coupling with electricity, heat, and mechanics will be instrumental in designing and drawing out technical specification.
同時，對直流電阻對焊過程進行電、熱、力耦合模擬也將會對焊接過程的認識、合理設計控制措施和制定合理的工藝規(guī)范有著重要意義。
