查询词典 oscillation

The code considers both transverse and longitudinal movements in the accelerators using a used 4 order variable step Runge Kutta method to calculate the beam envelope of the transverse movement, the phase oscillation curve of the longitudinal movement, the energy growth, the energy distribution at the exit, and the longitudinal electric and magnetic field distributions.

L INE- ACC/ PC程序同时考虑了加速器中的横向运动与纵向运动，运用了四阶变步长 Runge- Kutta法计算了行波电子直线加速器束流横向运动包络线、纵向运动相振荡曲线、能量增长、出口能量分布和纵向电场、磁场分布。由该程序对海关大型集装箱检测系统用加速器的 9Me V档进行调整计算，结果表明：该程序的设计结果与实际运行参数符合得很好。

We take sech form ansatz and solve the CNLS equations through variational approach. We obtain the analytical expression of nonlinear coupling term, which is in the lagrangian of CNLS. We apply a potential well model to analyze the interaction properties of self-trapping beams in detail, the results show that the interaction do not change the profile of the beams, two beams keep oscillating around their collective center periodically. The amplitude and period of this oscillation are both determined by initial separation of two beams.
