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.

只见几道猛烈的火焰向童博射去，童博闪过两道，然后打碎一个花盆，把花盆碎片向火焰射口准确的打过去，火焰机关是靠射出点燃的油，出口一但被堵，就一个个自己炸毁了，之后童博不知察觉什麼突然向上跃起，地面立刻向上垂直射出许多钢矛，要是武功稍差之人，一定被插成刺猬一样，可是童博双手持剑向下用力一劈，猛烈的剑气不但震开所有钢矛，还把地面打出个浅坑，童博落在浅坑中，一转身向墙边跑了过去
