输出束 meaning in Chinese

output beam
output bundle

Simulation on the a - magnet of 30mev linac is also done with the gpt code ; the movement picture of electron beam in a - magnet is presented ; the change of beams emittance , the compression effect of bunch length , change of energy dissipation and achromatic angle of true a - magnet are explored . this chapter mainly introduces some characteristics and properties of the main accelerate stage in 30mev linac system
利用gpt程序对30mevlinac中的-磁铁进行了动力学模拟，给出了电子束在-磁铁中的运动图像，研究了注入器输出束流经过-磁铁后束流发射度的变化、束团长度的压缩效应、能散度的变化以及-磁铁实际的消色散入射角。
Numeric simulation is done based on 30mev linac structure and the corresponding parts " parameters . the simulate result shows that the design of beam line is reasonable . the beam properties change very small when the drifting distance before the first acceleration stage is changed in the certain ranges
根据30mevlinac结构和元件参数进行了整体的数值模拟，模拟结果表明： 30mevlinac中各个加速段的结构与性能较好，输出束流的发射度和能散度都较小，束线的设计也较合理。
