利用数值模拟方法研究了加速场强、注入相位、束团大小、形状、电荷等因素对束流横向发射度产生的影响。

The effect of field strength, initial phase, bunch shape and charge on electron beam transverse emittance is also explored by numeric simulation method.

对于隔离的LDMOS器件，横向隔离壁(32)(结合至源极)与埋层(24)之间的电阻减少，从而减少了衬底注入电流。

For isolated LDMOS devices, the resistance between the lateral isolation wall (32) (tied to the source) and the buried layer (24) is reduced, thereby reducing substrate injection current.
