在原子核熔合反应或裂变反应的动力学过程中,颈部变量都起着非常重要的作用。通常情况下,模型中变量的定义根据各种描述宏观形变的参数的不同而不同。为了进一步研究颈部增长在核熔合反应中的作用,通过引入弹核和靶核的形变参量来拓展哑铃模型。在此框架下,计算了从两个接触核到生成一个复合核过程的核熔合反应系统在不同形变下的势能曲面,同时又对核熔合反应体系的惯性张量和粘滞张量进行了计算,这些物理量的计算都为以后的朗之万动力学研究打下了基础。计算结果表明,在改进后的五参数哑铃模型之中,颈部变量是不稳定度并在核反应中起重要作用。
In the nuclear fusion reaction or fission reaction kinetics, the neck variable plays a very important role. In general, the definition of variables in the model will vary depending on the various parameters that describe the macroscopic deformation. In order to further study the role of neck growth in the nuclear fusion reaction, the dumbbell model was expanded by introducing the deformation parameters of the bomb core and target nucleus. Under this framework, the potential energy surfaces under different deformations of the nuclear fusion reaction system from two contact nuclei to one composite nuclear process are calculated, and the inertial tensor and viscous tensor of the nuclear fusion reaction system are calculated , The calculation of these physical quantities laid the foundation for the study of Longwan million dynamics. The results show that in the improved five-parameter dumbbell model, the neck variable is unstable and plays an important role in the nuclear reaction.
