- Example Sentences:
| 1. | The large nuclear temperature evaluation would violate conservation of energy , and may lead a negative neutron kerma factor
这就可能使评价核温度太高而导致平均次级中子能量( ? )过大，破坏了能量守恒，而导致了负kerma因子。 | | 2. | 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。 | | 3. | 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。 | | 4. | It was found that the simple triangular shape distribution would cause " two - peaked " energy distribution near the threshold energy , which must affect the group transfer matrix
阈能处三角形能谱分布的近似描述，导致产生了群散射矩阵的“双峰”现象，而阈能处矩形能谱分布使平均次级中子能量( | | 5. | The rectangular shape would make the e ' _ ( n ) too large , which can violate conservation of energy and may lead a negative neutron kerma ( kinetic energy release in materials ) factor
)过大，从而产生负kerma ( kineticenergyreleaseinmaterials )因子。文档5中的次级中子数据以蒸发谱来描述时，一些核素也出现了负kerma因子现象。 | | 6. | In this paper , we will discuss the reason of these abnormal behaviors , and give some recommendation to modify the related data in the endf - vi ( or other nuclear data library , e . g . cendl - 2 etc . ) , to improve the energy balance to eliminate the problem
针对这两种不同的次级中子能谱描述方式，本文尝试用多种较简便方法来针对endf -库的相关数据做一定的修正，以改善某些能点的次级中子能谱的能量守恒问题。 | | 7. | The ddx of neutron emission is one of the most important nuclear data in nuclear design . more precise nuclear data , not only nuclear reaction data but also energy and angular distributions , are required by the development of nuclear engineering
次级中子双微分截面是核工程设计中重要的核数据之一，随着对核工程设计要求的日益提高，对核数据的要求也越来越高，不仅要求有精确的核反应截面数据，还要有精确的能谱和角分布数据。 | | 8. | 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。 | | 9. | Moreover , precise experimental data are the base of theoretical models and calculations . up to now , at about 14 mev , there are some ddx measurement data because the t ( d , n ) 4he reaction is a good mono - energetic neutron source . below 8 mev , there are also some measurements because mono - energetic neutron source is available in this region
到目前为止，在14mev附近，由于有很好的t ( d , n ) ~ 4he单能中子源，所以次级中子双微分截面的测量数据较多，在8mev以下，也可以得到很好的单能中子源，所以也有一些测量数据。 | | 10. | 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。 |
