This characteristic could be qualitatively explained as interference between σ amplitude and π amplitude of electrons final wavefunction. It also depends on the impact parameters: the π amplitude contribution is dominant at small impact parameters, which leads to a symmetric velocity distribution around the internuclear axis. However, At large impact parameters the σ amplitude contribution increases relatively, resulting into a asymmetric electrons velocity distribution around the internuclear axis.

出射电子的上述分布特征可由出射电子波函数σ振幅和π振幅的干涉进行定性解释，σ振幅和π振幅对出射电子波函数的贡献与碰撞参数相关，在小碰撞参数下，π振幅的贡献更加明显；而在大碰撞参数下，σ振幅的贡献更加显著。

Several fierce flames are shot to Po. He dodged two then breaks a flowerpot. He makes accurate shot with pieces of broken flowerpot to the outlet of flames. Flaming mechnisms are operated with burning oil so they explodes one by one since the outlets have been obstructed. Later, Po seems to notice something and jumps upward all at once. As soon as he jumped, many steel spears shoot out vertically. A person with inferior martial art must be stabbed into a hedgehog shape. Po, though, shocks away all spears with a heavy both-handed slash which sends out intense collision energy and even makes a shallow pit on the ground. Po lands in the pit then runs to the wall.
