Longitudinal "dispersion" functions are also calculated from the solved stationary distributions, which are very important for Landau damping and stability in bunched beam.

由定态分布的求解得出了对束团中的朗道阻尼和稳定性研究非常重要的纵向“色散”函数。

The nonlinear space charge effect of bunched beam in Hnac is one of the important reasons that induces the emittance growth because of the conversion of the field energy to kinetic energy.

直线加速器中电荷束团的非线性效应是导致束流发射度增长的一个重要原因。
