The effect of the spatial inhomogeneity of TEM mode on the electron beam-TEMwave field interaction has been discussed with the dynamic thcory.
电磁波与电子注的互作用不仅与电子注的特性有关，也与波场的极化、空间特性紧密相关。

The perfect boundary consistency conditions of total-scattered fields and the method to set TEMwave excitation source are proposed in 3-D cylindrical coordinates.
给出了柱坐标系下完整的总场 -散射场区的连接边界条件以及平面波源的设置方法。

In the meanwhile, irregular broken line and wave modeand fishbone like interface morphologies were observed by TEM.
