butt coupling

基本解释

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.
采用模场耦合理论，推导出多模光纤与单模光纤的直接耦合效率表达式，计算得到耦合效率与所选用的多模光纤和单模光纤的纤芯芯径之间的模拟关系。
The relation between coupling efficiency and mode field stimulated by SLD, fiber structures, shape of fiber butt and coupling operation parameters was analyzed.
分析了耦合效率与光源激发的光模场、光纤结构及光纤头部形状、耦合工作参数等因素的关系。
Simulation of DC flash butt welding by coupling with electricity, heat, and mechanics will be instrumental in designing and drawing out technical specification.
同时，对直流电阻对焊过程进行电、热、力耦合模拟也将会对焊接过程的认识、合理设计控制措施和制定合理的工艺规范有着重要意义。
