利用洛伦兹变换，画出了相对论下二体反应实验室系和动心系出射粒子动量的关系图，并利用关系图，对不同情况下的出射粒子能量分布作了讨论。

Using Lorentz transformation, a momentum vectors diagram of the emitted particle in laboratory frame and center-of-momentum frame is given in relativistic two-body reaction.

我们首先取出每个事例中测得的次级粒子出射极角的数据，并给出出射极角分布图(直方图)。

Firstly the data of polarized Angle of flying-out particles is extracted and its distribution (histogram) is given.

把传统的集合侧向流横向分析拓展到了纵向，建立了在末态粒子倾向性出射方向上对侧向流作定量分析的方法。

The traditional transverse analysis of the collective sideward flow is ex-tended to study the flow in longitudinal direction.

The second particle was deflected almost not at all. But what he could tell from the fact that there was a second particle at all, and the fact that it was in this direction, is that in addition to his negative particle, he also, of course, had a positive particle that was within this stream of rays that were coming out.

粒子的强烈信号,有着强烈的对比,第二个粒子几乎，不发生偏转，他能判断这是，第二个粒子的原因是它在这个方向,所以在出射射线中,除了有带负电的粒子外。
