摘要
讨论如何确定中子辐照量分布函数ρ(τ)=C_1(1-r)/△τr^(τ/△τ)=C_2/τ_0exp(-τ/τ_0)中的比例系数C_1和C_2的值。结果表明,C_1由归一化条件确定,通常取为1。但是C_2≠C_1,C_2/C_1的值完全由重叠因子r的值确定,即r=1时,C_2/C_1=1;0<r<1时,C_2/C_1=(r-1)/Inr。进一步的讨论还表明,0<r<1时,C_2/C_1小于1且随r增大而增大。
We discuss how to determine the coefficient C1 and C2 in the expression of neutron exposure distribution ρ(τ) = C1 (1- r)/△τrr/△r = C2/τoexp( -τ/τ0). The results show that C1 is determined by the normalization condition and generally taken as 1. And C2≠C1 ,C2/C1 is completely determined by the overlap factor r,i. e. ,C2/ C1 =1 when r=1 and C2/C1 =(r-1)/lnr when 0<r<1. The further discussion argues that when 0<r<1.C2/ C1 is less than 1 and increases with r.
