Meanwhile, the effects of processing parameters of EB brazing on the temperature field at optimal scanningtrack are discussed.
同时，讨论了最佳扫描轨迹下电子束钎焊工艺参数对温度场的影响。

The EB scanningtrack, scanning frequency and energy density distribution at heating zone could be programmed off-line and adjusted on-line.
利用该系统可对电子束扫描轨迹、扫描频率以及加热区域电子束能量密度的分配进行离线编辑和在线调节。
