| 摘 要： | 选择参考系是描述物体运动规律时的首要问题,同一物体的运动在不同参考系间物理量存在一定的变换关系.本文系统地论述了在相对论条件下两惯性参考系间物理量的变换公式,并将其运用到新的三裂变反应微观机制的研究中,将质心系中碎块的角分布转化成实验室系下的分布,结果表明实验和理论数值一致,得出该裂变模式主要发生在反应面附近,是经历了两次两体裂变的非平衡过程.

| Abstract: | The Selection of a reference system is the cardinal problem in describing the characteristics of a motion,and there exists some transformation relationship between the physical quantities when the same object is moving in different reference systems.This paper gives a systematic discussion about the transformation formula between two inertial reference systems under relativistic conditions,and applies it to research the micro-mechanism of a new ternary fission reaction,and the angular distribution of fragments in center-of-mass frame is thus transformed into one in laboratory frame.Our findings show a nice consistency with the theoretic values and it is concluded that the new fission mode takes place mostly reaction near the reaction plane and is a nonequilibrium process that undergoes two binary fissions. |
