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.
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。
The velocity of the center of mass has not changed as seen from your frame of reference, because the velocity of center of mass is always the same, remember, because momentum is conserved.
质量重心的速度，并没有发生改变，你在参照系中可以看出，因为质量重心的速度，总是保持不变，要记住，由于动量守恒。
