次级中子 meaning in English
secondary neutron
subsequent neutron
Examples
- 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。 - 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。 - 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( - 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。
