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 threshold energy formula of nuclear reaction in which energy is absorbed is obtained using laboratory frame. It is consistent with the result obtained in mass center frame.

在实验室坐标系下，给出吸能核反应所要求的阈能，其结果与质心系下得到的结果完全一致。

Data measured in the laboratory frame were converted to that in the center-of-mass frame to obtain product kinetic energy distributions and angular distributions in the center-of-mass frame.

通过把实验数据从实验室坐标系转化到质心坐标系，得到反应产物在不同质心角度下的平动能分布和角度分布。

Mr Vlahos's breakthrough was to create a complicated laboratory process which involved separating the blue, green and red parts of each frame before combining them back together in a certain order.
