横向发射 meaning in Chinese

broadside launching

The effect of field strength , initial phase , bunch shape and charge on electron beam transverse emittance is also explored by numeric simulation method
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 electromagnetism field of the accelerator cavity is analyzed , and the movement of electron in the cavity also analyzed . the vibration rule of transverse emittance is acquired when the electron beams move in the accelerator cavity , and the result complies with the numeric simulation
分析了rf - gun加速腔中的电磁场结构和电子运动规律，得到电子束在加速腔中运动时束流横向发射度是振荡变化的，与数值模拟结果吻合。
