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。
The solution to the nonlinear equation satisfied by the probability of neutron-initiated persistent fission chain is discussed in the system whose configuration does not change with time. The related physics of perturbation approximation process is discussed. In particular, the relationship between the effective coefficient of neutron source and the effective coefficient of neutron source in the sense of neutron multiplication is discussed . In addition, the method of solving the perturbation approximation and the solution of not perturbing the perturbation approximation are also discussed, which do not reduce the number of nonlinear equations satisfied by the probability of sustained fission chain induced by neutron.
