Some pores appeared mainly near in the bond line, but porosity can be suppressed to a great extent by increasing welding speed or electronbeamscanning.
结果表明，在保证试件完全焊透的情况下，降低电子束的线能量，可在一定程度上提高接头的强度；

This paper carries on the three-dimensional static electromagnetic field analysis on the electronbeamscanning deflection coil with multi pole shoe structure.
根据不锈钢毛细管板结构的钎焊特点，建立了扫描电子束钎焊温度场三维有限元分析模型。
