secondary neutron meaning in Chinese
次级中子
Examples
- As well known , in the file 5 of endf - vi , the energy distribution of secondary neutron are represented by various analytical formulations
众所周知，在评价核数据库endf -版的文档5中，次级中子能量分布数据以不同的表达方式来描述。 - When the energy distribution of secondary neutron are represented by evaporation spectrum ( lf = 9 ) , care must be taken in describing the nuclear temperature near the threshold
通过分析发现，评价次级中子能谱数据所采用的蒸发谱模型大都忽略了能级密度参数与激发能之间的关联。 - The double differential cross section ( ddx ) of neutron emission from 51v at 10 . 26 mev neutrons was measured using normal and abnormal fast neutron tof spectrometers on hi - 13 tandem accelerator in china institute of atomic energy ( ciae ) . the problem of influence from breakup neutrons of the d ( d , n ) neutron source on secondary neutron spectra was successfully solved
用中国原子能科学研究院hi - 13串列加速器上的常规和非常规快中子飞行时间谱仪，测量了10 . 26mev中子引起~ ( 51 ) v的次级中子双微分截面，成功解决了d ( d ， n )中子源中破裂中子对次级谱的影响。 - The measurement data is scarce in 8 - 13 mev region due to the lack of mono - energetic neutron sources ( in this region , there are breakup neutrons besides the mono - energetic neutrons in the often used neutron sources such as t ( p , n ) 3 he and d ( d , n ) 3he sources . the secondary neutrons induced by breakup source neutrons will seriously contaminate the secondary neutron spectra induced by mono - energetic source neutrons ) . therefore , precise measurement for some key nuclides is necessary to check the evaluations in this region
但在8 ? 13mev这一能区，由于没有合适的单能中子源(因为在这一能区，对于常规中子源如t ( p , n ) ~ 3he和d ( d , n ) ~ 3he中子源，除了单能中子以外，还有破裂中子成份，这部分源破裂中子在样品上引起的次级中子，将严重影响测量结果) ，所以至今在8 ? 13mev能区这方面的测量数据极少。
