【摘要】 讨论了构形不随时间变化的系统中中子引发持续裂变链概率所满足非线性方程的求解途径。对微扰近似处理的相关物理进行了讨论,特别是讨论了在中子引发持续裂变链意义上中子源的有效性系数和在中子增殖意义上中子源的有效性系数的差异和关系。另外还讨论了不降低中子引发持续裂变链概率所满足的非线性方程次数的微扰近似处理的求解途径和不做微扰近似的求解途径。更多还原

【Abstract】 The methods are discussed in detail for the solution of the non-linear equation satisfied by the probability, as a function of neutron position, energy and moving direction, of a source neutron sponsoring a persistent fission chain in a system whose configuration does not change with time. The differences between the effectiveness coefficient of a neutron source in the sense of its sponsoring persistent fission chains and the effectiveness coefficient of the neutron source in the sense of neutron multiplication are also discussed.更多还原
